PROXY STATEMENT

QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING AND VOTING

Why did I receive these proxy materials?

We are providing these proxy materials in connection with the solicitation by the Board of Directors of Owens Corning (“Owens Corning,” the “Company,” “we,” “us” or “our”), a Delaware corporation, on behalf of the Company of proxies to be voted at our 2015 Annual Meeting of Stockholders (the “Annual Meeting”) and at any adjournment or postponement thereof. On or about March 12, 2015, we began distributing these proxy materials to stockholders.

How can I attend the Annual Meeting?

You are invited to attend the Annual Meeting on April 16, 2015, beginning at 10:00 a.m., Eastern Daylight Time. The Annual Meeting will be held at the offices of Sidley Austin LLP, 787 Seventh Avenue, New York, New York 10019. Only stockholders who are eligible to vote at the Annual Meeting or their authorized representatives will be admitted. Stockholders must present one form of photo identification to be admitted to the Annual Meeting. If you are a beneficial owner of shares, you also must present a brokerage statement or other proof of ownership to be admitted. No cameras, recording equipment, electronic devices, large bags, briefcases or packages will be permitted in the Annual Meeting. Seating will be limited.

Who is entitled to vote at the Annual Meeting?

Holders of Owens Corning common stock at the close of business on February 25, 2015, the record date for the Annual Meeting, are entitled to receive this Proxy Statement and to vote their shares at the Annual Meeting. As of that date, there were 118,247,213 shares of common stock outstanding and entitled to vote. Each share of common stock is entitled to one vote on each matter properly brought before the Annual Meeting. All stockholders of record may vote in person at the Annual Meeting. Stockholders of record may also be represented by another person by executing a proper proxy designating that person. If you are a beneficial owner of shares, you must obtain a legal proxy from your broker, bank or other holder of record and present it to the inspectors of election with your ballot in order to vote at the Annual Meeting.

The names of stockholders of record entitled to vote at the Annual Meeting will be available for any purpose germane to the meeting at the Annual Meeting and for ten days prior to the Annual Meeting between the hours of 8:45 a.m. and 4:30 p.m., at our principal executive offices at One Owens Corning Parkway, Toledo, Ohio, 43659 by contacting the Secretary of the Company.

How do I vote?

You may vote using one of the following methods:

• vote through the Internet at www.proxyvote.com using the instructions included on the proxy card or voting instruction card;

• vote by telephone using the instructions on the proxy card or voting instruction card;

• complete and return a written proxy or voting instruction card; or

• attend and vote at the Annual Meeting. (See “Who is entitled to vote at the Annual Meeting?”)

Your vote is important. Please vote promptly.

Will my shares be voted if I do not provide instructions to my broker?

If you are the beneficial owner of shares held in “street name” by a broker, the broker (as the record holder of the shares) is required to vote those shares in accordance with your instructions. If you do not provide

1

instructions, your broker will not be able to vote your shares on “non-discretionary” proposals. The only item at the Annual Meeting that is “discretionary” is the ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm. Accordingly, if you are a beneficial owner, your broker or other holder of record is permitted to vote your shares on the ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm, even if the stockholder of record does not receive voting instructions from you.

What can I do if I change my mind after I vote my shares?

If you are a stockholder of record, you can revoke your proxy before it is exercised by:

• written notice to the Secretary of the Company;

• timely delivery of a valid, later-dated proxy or a later-dated vote by telephone or on the Internet; or

• voting by ballot at the Annual Meeting.

If you are a beneficial owner of shares, you may submit new voting instructions by contacting your broker or other holder of record.

All shares that have been properly voted and not revoked will be voted at the Annual Meeting.

What are the voting requirements to elect the directors and to approve the proposals discussed in this Proxy Statement?

The presence of the holders of a majority of the shares of common stock entitled to vote at the Annual Meeting, present in person or represented by proxy, is necessary to constitute a quorum.

• Election of Directors

A plurality of the votes cast is required for the election of directors. This means that the director nominee with the most votes for a particular slot is elected for that slot. You may vote “for” or “withhold” with respect to the election of directors. Only votes “for” are counted in determining whether a plurality has been cast in favor of a director. Abstentions are not counted for purposes of the election of directors.

• Ratification of the Selection of PricewaterhouseCoopers LLP

Although ratification is not required by our Bylaws or otherwise, we are asking our stockholders to ratify the Audit Committee’s selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2015. The affirmative vote of a majority of the votes which could be cast by the holders of all stock entitled to vote which are present in person or by proxy at the Annual Meeting is required to approve the ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2015. Abstentions will count as present and entitled to vote for purposes of this proposal and will have the effect of a vote against the proposal.

• Say on Pay

The affirmative vote of a majority of the votes which could be cast by the holders of all stock entitled to vote which are present in person or by proxy at the Annual Meeting is required to approve, on an advisory basis, the compensation of our named executive officers. Abstentions will count as present and entitled to vote for purposes of this proposal and will have the effect of a vote against the proposal.

2

Could other matters be decided at the Annual Meeting?

At the time this Proxy Statement went to press, we did not know of any matters to be raised at the Annual Meeting other than those referred to in this Proxy Statement. However, if other matters should be properly presented at the meeting, the proxy holders will have the discretion to vote your shares in accordance with their best judgment.

Who will tabulate the votes?

Representatives of Broadridge Financial Solutions, Inc. will tabulate the votes and act as inspector of election. John W. Christy and Raj B. Dave have been appointed to serve as alternate inspectors of election in the event Broadridge is unable to serve.

Who will pay the cost of this proxy solicitation?

The Company will pay the cost of soliciting proxies. Proxies may be solicited on our behalf by directors, officers or employees in person or by telephone, electronic transmission or facsimile transmission, and such persons will not receive additional compensation for their solicitation efforts. We have hired Alliance Advisors, L.L.C. to assist in the distribution and solicitation of proxies for a fee of $20,000, plus reasonable expenses, for these services.

What is “householding” and how does it affect me?

We have adopted a procedure approved by the U.S. Securities and Exchange Commission (“SEC”) called “householding.” This procedure is designed to reduce the volume of duplicate information received at your household and helps us reduce our printing and mailing costs. Under this procedure, stockholders of record who have the same address and last name and do not participate in electronic delivery of proxy materials will receive only one copy of our Notice of Annual Meeting and Proxy Statement and accompanying documents, unless one or more of these stockholders notifies us otherwise.

Stockholders who participate in householding will continue to receive separate proxy cards.

If you are eligible for householding, but you and other stockholders of record with whom you share an address currently receive multiple copies of the Notice of Annual Meeting and Proxy Statement and accompanying documents, or if you hold stock in more than one account, and in either case you wish to receive only a single copy of each of these documents for your household, contact Broadridge Financial Solutions, Inc. at 1-800-542-1061 or in writing at Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York 11717.

If you participate in householding and wish to receive a separate copy of this Notice of Annual Meeting and Proxy Statement and the accompanying documents, or if you do not wish to participate in householding and prefer to receive separate copies of these documents in the future, please contact Broadridge as indicated above.

Beneficial owners can request information about householding from their brokers or other holders of record.

PROPOSAL 1

ELECTION OF DIRECTORS

Information Concerning Directors

Currently, our Board of Directors consists of 13 directors in three classes, with four directors in Class III, four directors in Class I and five directors in Class II. One Class III director, Mr. Blake, will retire at the Annual Meeting.

• The directors currently serving in Class III hold office for a term expiring at the Annual Meeting.

• The directors currently serving in Class I hold office for a term expiring at the Annual Meeting of Stockholders in 2016.

• The directors currently serving in Class II hold office for a term expiring at the Annual Meeting of Stockholders in 2017.

The directors in Class III whose terms expire at the Annual Meeting are: James J. McMonagle, W. Howard Morris and Suzanne P. Nimocks. Pursuant to the Corporate Governance Guidelines, adopted by our Board of Directors, the retirement age for directors is 73. A director who has attained age 73 may continue to serve as a director until the next succeeding annual meeting of stockholders. Norman P. Blake has attained retirement age and will retire at the Annual Meeting. Upon his retirement, the then current size of the Board of Directors will be reduced by one.

Pursuant to the Corporate Governance Guidelines, nominees for director are selected on the basis of, among other things, experience, knowledge, skills, expertise, mature judgment, acumen, character, integrity, diversity, ability to make independent analytical inquiries, understanding of Owens Corning’s business environment, and willingness to devote adequate time and efforts to Board responsibilities. The Board of Directors believes that each of the current directors and nominees for director exhibit each of these characteristics. Set forth below with each director’s biographical information is a description of the principal experience, qualifications, attributes or skills that led the Board to the conclusion that each individual should serve as an Owens Corning director.

Your proxy will vote for each of the three nominees unless you specifically withhold authority to vote for any or all of the nominees. If any nominee is unable to serve, your proxy may vote for another nominee proposed by the Board of Directors. We do not know of any nominee of the Board of Directors who would be unable to serve as a director if elected.

Directors will be elected by a plurality of the votes cast at the Annual Meeting. Each person elected at the Annual Meeting will serve until the Annual Meeting of Stockholders in 2016 and until his/her successor is duly elected and qualified.

Phased-In Declassification of the Board

At our Annual Meeting of Stockholders in 2014, the stockholders voted to declassify the Board of Directors in a transitional manner beginning with annual elections for directors in Class III in 2015. Accordingly, the Board of Directors has nominated each of Ms. Nimocks and Messrs. McMonagle and Morris for re-election as directors at the Annual Meeting for a new term expiring at the Annual Meeting of Stockholders in 2016.

The Board of Directors recommends that you vote FOR each director nominee named in Proposal 1.

2016 Management Proposal on Majority Voting

The Board plans to submit a proposal at the 2016 Annual Meeting of Stockholders for stockholder approval of majority voting in uncontested director elections to become effective concurrent with the full de-classification of the Board in 2017.

Corporate Governance Guidelines

Our Board of Directors has adopted Corporate Governance Guidelines which, in conjunction with our Certificate of Incorporation, Bylaws and Board committee charters, form the framework for our corporate governance. The Governance and Nominating Committee reviews the Corporate Governance Guidelines periodically and makes revisions, as necessary. The Corporate Governance Guidelines are published on our website at http://www.owenscorning.com and will be made available in print upon request by any stockholder to the Secretary of the Company.

Board Leadership Structure

Pursuant to the Corporate Governance Guidelines, the Board has the authority to select its Chairperson based on its collective best judgment as to the candidate best suited to meet the Company’s needs at a given time. Currently, Michael H. Thaman serves as Owens Corning’s Chairman of the Board, President and Chief Executive Officer (“Chairman and CEO”) and Ralph F. Hake, a non-management director with extensive public company experience serves as lead independent director (“Lead Independent Director”) of the Board. The Board of Directors believes that this leadership structure is appropriate for Owens Corning in light of the Company’s governance structure, current needs and business environment as well as the unique talents, experiences and attributes of the individuals in those roles.

11

Mr. Thaman was Chairman of the Board of the Company from April 2002 to December 2007, prior to his election as the Company’s Chief Executive Officer. Upon his election as Chief Executive Officer in December 2007, the Chairman and CEO positions were combined in order to ensure a single, strong senior management voice, with clear and consistent leadership on critical strategic objectives. The Board’s prior experience working with Mr. Thaman in the Chairman position strongly supported its conclusion that the Company and its stockholders would be best served with Mr. Thaman leading Owens Corning as its Chairman and CEO.

The Board of Directors further determined that it was appropriate to have a structure that provided strong leadership among the independent directors of the Board. Our Lead Independent Director, Mr. Hake, has served as director of the Company since 2006, including as the chairman of various Board committees and has also had significant experience serving as a non-management director of public companies other than Owens Corning. Additionally, the Board, which consists entirely of independent directors other than Mr. Thaman, exercises an independent oversight function. Each of the Board committees (other than the Executive Committee) is comprised entirely of independent directors. The independent directors meet in executive session regularly and each year, they complete an evaluation of the Chairman and CEO in several key areas.

The Board of Directors has complete access to the Company’s management and believes that its ongoing ability to review the leadership structure of the Board and to make changes as it deems necessary and appropriate gives it the flexibility to meet varying business, personnel and organizational needs over time.

Lead Independent Director

The independent directors on our Board of Directors have elected a Lead Independent Director to serve in a lead capacity to coordinate the activities of the other non-management directors and to perform such other duties and responsibilities as the Board of Directors may determine. Ralph F. Hake was elected to serve as Lead Independent Director effective April 2011 and re-elected for another two-year term effective as of April 2013.

The responsibilities of the Lead Independent Director, as provided in the Charter of Lead Independent Director for Owens Corning, include:

• presiding at meetings of the Board in the absence of, or upon the request of, the Chairman;

• serving as a designated member of the Executive Committee;

• presiding over all executive meetings of non-management directors and independent directors and reporting to the Board, as appropriate, concerning such meetings;

• reviewing Board meeting agendas in collaboration with the Chairman and recommending matters for the Board to consider and information to be provided to the Board;

• serving as a liaison and supplemental channel of communication between the non-management/independent directors and the Chairman without inhibiting direct communication between the Chairman and other directors;

• serving as the principal liaison for consultation and communication between the non-management/independent directors and stockholders; and

• advising the Chairman concerning the retention of advisors and consultants who report directly to the Board.

The Charter of Lead Independent Director for Owens Corning is available on our website at http://www.owenscorning.com. The Board of Directors evaluates its structure and composition annually and believes that having a strong Lead Independent Director with significant leadership responsibilities, as described above, coupled with a strong and effective Chairman and CEO is currently the appropriate board leadership structure for Owens Corning.

12

Board, Committee and Chairman/CEO Evaluation Process

Each year, the Governance and Nominating Committee facilitates a process to evaluate the effectiveness of the Board, its committees and the Chairman and CEO.

The Board and its committees complete self-assessment questionnaires that evaluate effectiveness in several areas including composition, structure and processes. The Governance and Nominating Committee utilizes the results of the questionnaires to recommend changes to Board processes, to determine critical skills required of prospective director candidates and to make recommendations for committee assignments.

The Governance and Nominating Committee also prepares and circulates evaluations to the non-management directors regarding the performance of the Chairman and CEO in several key performance areas. The results of the evaluations are discussed in an executive session of the non-management directors and are also factored into the Compensation Committee’s performance evaluation of the Chairman and CEO.

Director Retirement Age

Pursuant to the Corporate Governance Guidelines, the retirement age for directors is 73. A director who has attained age 73 may continue to serve as a director until the next succeeding Annual Meeting of Stockholders.

Risk Oversight

The Audit Committee of the Board of Directors has primary responsibility for assisting the Board’s oversight of risk. Pursuant to its charter, the Audit Committee’s responsibilities include discussing guidelines and policies governing the process by which senior management and the relevant departments of the Company access and manage the Company’s exposure to risk. The Compensation and Finance Committees of the Board of Directors also review and evaluate risks associated with their respective areas. Each of the Board Committees provides reports concerning its respective risk management activities to the Board of Directors and the Board considers and discusses such reports.

Owens Corning also has a management Risk Committee which is responsible for overseeing and monitoring the Company’s risk assessment and mitigation related actions. The Risk Committee’s membership has broad based functional representation, including members from the corporate audit, finance, legal, security, treasury and business functions. The Risk Committee provides periodic updates concerning risk to the Audit Committee of the Board of Directors.

Communications with Directors

Stockholders and other interested parties may communicate with the Lead Independent Director or any other non-management director by sending an email to non-managementdirectors@owenscorning.com. All such communications are promptly reviewed by the Vice President, Internal Audit and the Senior Vice President and General Counsel for evaluation and appropriate follow-up. The Board of Directors has determined that communications determined to be advertisements, or other types of “Spam” or “Junk” messages, unrelated to the duties or responsibilities of the Board, should be discarded without further action. A summary of all other communications is reported semi-annually to the non-management directors. Communications alleging fraud or serious misconduct by directors or executive officers are immediately reported to the Lead Independent Director. Complaints regarding business conduct policies, corporate governance matters, accounting controls or auditing are managed and reported in accordance with Owens Corning’s existing Audit Committee complaint policy or business conduct complaint procedure, as appropriate.

13

Director Qualification Standards

Pursuant to New York Stock Exchange listing standards, our Board of Directors has adopted Director Qualification Standards with respect to the determination of director independence that incorporate the independence requirements of the New York Stock Exchange corporate governance listing standards. The standards specify the criteria by which the independence of our directors will be determined, including strict guidelines for directors and their immediate families with respect to past employment or affiliation with the Company or its independent registered public accounting firm. The full text of our Director Qualification Standards is available on our website at http://www.owenscorning.com. Using these standards, the Board determines whether a director has a material relationship with the Company other than as a director.

Director Independence

With the assistance of legal counsel, the Governance and Nominating Committee reviewed the applicable legal standards for director and Board Committee independence, our Director Qualification Standards, and the criteria applied to determine “audit committee financial expert” status. The Committee also reviewed reports of the answers to annual questionnaires completed by each of the independent directors and of transactions with director affiliated entities. On the basis of this review, the Governance and Nominating Committee delivered reports and recommendations to the Board of Directors and the Board made its independence and “audit committee financial expert” determinations based upon the Committee’s reports and recommendations.

The Board of Directors has determined that current directors Norman P. Blake, Cesar Conde, Jr., J. Brian Ferguson, Ralph F. Hake, F. Philip Handy, Ann Iverson, Edward F. Lonergan, James J. McMonagle, W. Howard Morris, Suzanne P. Nimocks, Maryann T. Seaman and John D. Williams are independent under the standards set forth in our Director Qualification Standards and applicable New York Stock Exchange listing standards. Prior to his retirement from the Board on April 17, 2014, the Board had determined that Joseph F. Neely was independent under such standards. The Board of Directors also has determined that all of the directors serving on the Audit, Compensation, and Governance and Nominating Committees are independent and satisfy relevant requirements of the SEC, the New York Stock Exchange, Owens Corning and the respective charters for the members of such committees.

Executive Sessions of Directors

Our Corporate Governance Guidelines specify that executive sessions or meetings of non-management directors without management present must be held regularly (at least three times a year) and at least one meeting must include only independent directors. Currently, all of our non-management directors are independent. In 2014, the independent directors met in executive session six times. Our Lead Independent Director presides over all executive sessions of non-management directors and independent directors.

Owens Corning Policies on Business Ethics and Conduct

Code of Business Conduct Policy

All of our employees, including our Chief Executive Officer, Chief Financial Officer and Controller, are required to abide by Owens Corning’s Code of Business Conduct Policy to ensure that our business is conducted in a consistently legal and ethical manner. This policy forms the foundation of a comprehensive process that includes compliance with all corporate policies and procedures, an open relationship among colleagues that contributes to good business conduct, and the high integrity level of our employees. Our policies and procedures cover all areas of professional conduct, including employment policies, conflicts of interest, intellectual property and the protection of confidential information, as well as strict adherence to all laws and regulations applicable to the conduct of our business.

14

Ethics Policy for Chief Executive and Senior Financial Officers

The Company also has adopted an Ethics Policy for Chief Executive and Senior Financial Officers that applies to our Chief Executive Officer, Chief Financial Officer and Controller (“Senior Financial Officers”), that provides, among other things, that Senior Financial Officers must comply with all laws, rules and regulations that govern the conduct of the Company’s business and that no Senior Financial Officer may participate in a transaction or otherwise act in a manner that creates or appears to create a conflict of interest unless the facts and circumstances are disclosed to and approved by the Governance and Nominating Committee.

Employees are required to report any conduct that they believe to be an actual or apparent violation of Owens Corning’s Policies on Business Ethics and Conduct.

The Sarbanes-Oxley Act of 2002 requires audit committees to have procedures to receive, retain and treat complaints received regarding accounting, internal accounting controls or auditing matters and to allow for the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters. We have adopted and comply with such procedures.

Directors’ Code of Conduct

The members of our Board of Directors are required to comply with a Directors’ Code of Conduct (the “Code”). The Code is intended to focus the Board and the individual directors on areas of ethical risk, help directors recognize and deal with ethical issues, provide mechanisms to report unethical conduct, and foster a culture of honesty and accountability. The Code covers all areas of professional conduct relating to service on the Owens Corning Board, including conflicts of interest, unfair or unethical use of corporate opportunities, strict protection of confidential information, compliance with all applicable laws and regulations, sustainability and oversight of ethics and compliance by employees of the Company.

The full texts of our Code of Business Conduct Policy, Ethics Policy for Chief Executive and Senior Financial Officers and Directors’ Code of Conduct are published on our website at http://www.owenscorning.com and will be made available in print upon request by any stockholder to the Secretary of the Company. To the extent required by applicable SEC rules or New York Stock Exchange listing standards, we intend to post any amendments to or waivers from the Ethics Policy for Chief Executive and Senior Financial Officers to our website under the tab entitled “Corporate Governance”.

BOARD AND COMMITTEE MEMBERSHIP

Our business, property and affairs are managed under the direction of our Board of Directors. Members of our Board are kept informed of our business through discussions with our Chief Executive Officer, Chief Financial Officer and other officers, by reviewing materials provided to them, by visiting our offices and plants, and by participating in meetings of the Board and its Committees. Board members are expected to regularly attend Board and Committee meetings as well as our Annual Meetings of Stockholders, unless an emergency prevents them from doing so. Each of our directors, who was a director at the time, was present at the 2014 Annual Meeting of Stockholders.

During 2014, the Board of Directors met six times. Each of our directors attended at least 75 percent of the meetings of the Board and Board Committees on which he or she served in 2014.

Each of the standing Committees of our Board of Directors acts pursuant to a charter that has been approved by our Board. These charters are evaluated and updated periodically and can be found on the Company’s website at http://www.owenscorning.com and will be made available in print upon request by any stockholder to the Secretary of the Company.

Director Service on Other Public Company Boards

Our Corporate Governance Guidelines state that directors who are employed full time as executives shall not serve on more than three publicly traded company boards (including service on the Company’s Board) and other directors shall not serve on more than five boards of publicly-traded companies (including service on the Company’s Board). This is to ensure that our directors devote adequate time for preparation and attendance at Board and Committee meetings as well as the Annual Meeting of Stockholders.

The Company’s Audit Committee Charter states that no director may serve as a member of the Audit Committee if such director serves on the audit committees of more than two other publicly traded companies, unless the Board determines that such simultaneous service would not impair the ability of such director effectively to serve on our Audit Committee.

The Audit Committee

Responsibilities

The Audit Committee is responsible for preparing the Audit Committee report required by SEC rules and assisting the Board in fulfilling its legal and fiduciary obligations with respect to oversight matters involving the accounting, auditing, financial reporting, internal control and legal compliance functions of the Company, including assisting the Board’s oversight of:

• the integrity of the Company’s financial statements,

• the Company’s compliance with legal and regulatory requirements,

• the Company’s independent registered public accounting firm’s qualifications and independence, and

• the performance of the independent registered public accounting firm and the Company’s internal audit function.

16

The Board of Directors has determined that each member of the Audit Committee is an “audit committee financial expert” for purposes of the SEC’s rules.

Audit Committee Report

The Audit Committee has reviewed and discussed the audited financial statements of the Company contained in the Annual Report on Form 10-K with management. The Committee has discussed with PricewaterhouseCoopers LLP the matters required to be discussed by Auditing Standard No. 16, “Communications with Audit Committees,” as amended, as adopted by the Public Company Accounting Oversight Board (“PCAOB”). The Committee has also received the written disclosures and the letter from PricewaterhouseCoopers LLP per the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, and has discussed with PricewaterhouseCoopers LLP its independence.

Based on the review and discussions referred to in the preceding paragraph, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company’s annual report on Form 10-K for the year ended December 31, 2014, for filing with the SEC.

17

The Compensation Committee

Responsibilities

The Compensation Committee is responsible for oversight of the Company’s executive compensation, including authority to determine the compensation of the executive officers, and for producing an annual report on executive compensation in accordance with applicable rules and regulations. The Compensation Committee may delegate power and authority to subcommittees of the Compensation Committee as it deems appropriate. However, the Compensation Committee may not delegate to a subcommittee any power or authority required by any law, regulation or listing standard required to be exercised by the Compensation Committee as a whole. The Compensation Committee has the sole authority to retain or terminate a compensation consultant to assist the Compensation Committee in carrying out its responsibilities, including sole authority to approve the consultant’s fees and other retention terms. The consultant’s fees will be paid by the Company.

In overseeing the Company’s policies concerning executive compensation for officers, the Compensation Committee:

• reviews at least annually the goals and objectives of the Company’s plans, and amends or recommends that the Board amend, these goal and objectives if the Compensation Committee deems it appropriate;

• reviews at least annually the Company’s executive officer compensation plans in light of the Company’s goals and objectives, and, if the Compensation Committee deems it appropriate, adopts or recommends to the Board the adoption of new, or the amendment of existing, executive compensation plans;

• evaluates annually the performance of the Chief Executive Officer in light of the goals and objectives of the Company’s executive compensation plans and, either alone as a committee or together with the other independent directors, sets the Chief Executive Officer’s compensation level based on this evaluation;

• approves the pay structure, salaries and incentive payments of all other executive officers of the Company, as well as the performance requirements for the Company’s annual and long-term incentive plans; and

• reviews and approves any severance or termination arrangements to be made with any executive officer of the Company.

The Compensation Committee also reviews the Company’s executive compensation programs on a continuing basis to determine that they are properly integrated and that payments and benefits are reasonably related to executive and Company performance and operate in a manner consistent with that contemplated when the programs were established.

Compensation Consultant

The Executive Compensation group in the Company’s Corporate Human Resources Department supports the Compensation Committee in its work. In addition, the Compensation Committee has authority to engage the services of outside advisors, experts and others to assist the Compensation Committee.

The Compensation Committee has engaged the services of Pearl Meyer & Partners (“Consultant” or “Pearl Meyer”) as independent outside compensation consultants to advise the Compensation Committee on all matters related to Chief Executive Officer and other executive, as well as director, compensation. Specifically, Pearl Meyer provided relevant market data and trend information, advice, alternatives and recommendations to the Compensation Committee.

18

The Governance and Nominating Committee

Responsibilities

The Governance and Nominating Committee is responsible for:

• identifying and recommending to the Board individuals qualified to serve as directors and as committee members;

• advising the Board with respect to Board composition, procedures and committees;

• advising the Board with respect to the corporate governance principles applicable to the Company; and

• overseeing the annual evaluation of the Board.

Director Nomination Process

The Governance and Nominating Committee evaluates potential candidates for Board membership on an ongoing basis. The Committee is authorized to use any methods it deems appropriate for identifying candidates for Board membership, including recommendations from current Board members, outside search firms and stockholders. Where outside search firms are utilized, they assist the Committee in both identifying and evaluating potential nominees. Based on an external search performed by an outside firm under the direction of our Governance and Nominating Committee, Ms. Seaman and Mr. Conde were identified as director candidates and elected to the Board effective August 4, 2014.

Director Qualifications

Pursuant to the Company’s Corporate Governance Guidelines, nominees for director are selected on the basis of, among other things, experience, knowledge, skills, expertise, mature judgment, acumen, character, integrity, diversity, ability to make independent analytical inquiries, understanding of the Company’s business environment, and willingness to devote adequate time and effort to Board responsibilities.

Consideration of Diversity

Pursuant to its charter, the Governance and Nominating Committee is responsible for identifying and recommending director nominees consistent with the director qualification criteria described above, including diversity, so as to enhance the Board’s ability to manage and direct the affairs and business of the Company. In identifying director nominees, the Committee considers diversity as provided in its charter and the Corporate Governance Guidelines but it does not have an additional policy with respect to the consideration of diversity. The Committee considers diversity expansively against the charter standard of enhancing the Board’s ability to manage and direct the affairs and business of the Company. The effectiveness of this process is assessed annually by the full Board as part of the Board self-evaluation process. The Committee believes that its consideration of diversity effectively implements the requirements of the charter and the Corporate Governance Guidelines.

Consideration of Director Candidates Recommended by Stockholders

Under its charter, the Governance and Nominating Committee is responsible for reviewing stockholder nominations for director. The Committee does not have a formal policy with respect to the consideration of director candidates recommended by stockholders. However, its practice is to consider those candidates on the same basis and in the same manner as it considers recommendations from other sources. Such recommendations should be submitted to the non-management directors and should include information about the background and qualifications of the candidate.

The Executive Committee

The Executive Committee has the authority to act for the Board between meetings of the Board of Directors subject to applicable law and New York Stock Exchange listing standards.

19

The Finance Committee

The Finance Committee is responsible for exercising oversight responsibility with respect to the Company’s material and strategic financial matters, including those related to investment policies and strategies, merger and acquisition transactions, financings, capital structure, and for advising Company management and the Board with respect to such matters.

REVIEW OF TRANSACTIONS WITH RELATED PERSONS

There are no transactions with related persons, as defined in Item 404 of Regulation S-K, to report for the fiscal year ended December 31, 2014.

The Company has various written policies in place pertaining to related party transactions and actual or potential conflicts of interest by directors, officers, employees, and members of their immediate families.

The Company has a Directors’ Code of Conduct that provides, among other things, that a director who has an actual or potential conflict of interest:

• must disclose the existence and nature of such actual or potential conflict to the Chairman of the Board and the Chairman of the Governance and Nominating Committee; and

• may proceed with the transaction only after receiving approval from the Governance and Nominating Committee.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934 and SEC regulations require Owens Corning’s directors and executive officers and greater than ten percent stockholders to file reports of ownership on Form 3 and changes in ownership on Forms 4 or 5 with the SEC. Owens Corning undertakes to file such forms on behalf of our current reporting directors and executive officers pursuant to a power of attorney given to certain attorneys-in-fact. Reporting directors, executive officers and ten percent stockholders are also required by SEC rules to furnish Owens Corning with copies of all Section 16(a) reports they file.

Based solely on our review of copies of such reports received and/or written representations from such directors and executive officers and ten percent stockholders, Owens Corning believes that all Section 16(a) filing requirements applicable to its directors, executive officers and ten percent stockholders were complied with during fiscal year 2014.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis^*

In this section, we discuss our compensation philosophy and describe the compensation program for our Chief Executive Officer (“CEO”), Chief Financial Officer (“CFO”) and our next three most highly paid executive officers (collectively “named executive officers” or “NEOs”). We also provide information regarding

Charles Dana, who was a NEO during the fiscal year. We explain how our Board’s Compensation Committee (the “Committee”) determines compensation for our senior executives and its rationale for specific 2014 decisions. We also discuss several changes the Committee has made to our program over the past year to advance its fundamental objective of aligning our executive compensation with the long-term interests of Owens Corning’s stockholders.

Response to Say-on-Pay Vote and Stockholder Outreach in 2014

In 2014, we provided our stockholders with the opportunity to approve, or vote against, the 2013 compensation of our NEOs (“say-on-pay”). Approximately 67% of the votes cast approved the executive compensation program. We are committed to ensuring that our investors fully understand our executive compensation program, including how it aligns the interests of our executives with our stockholders and how it rewards the achievement of our strategic objectives. We also want to understand what our stockholders think about executive compensation, beyond the say on pay vote. To this end, we determined that a stockholder outreach effort was necessary and important in order to obtain a deeper understanding of our investors’ beliefs with regards to our compensation program.

We engaged in an extensive stockholder outreach effort during 2014, contacting our top 50 investors, representing the holders of over 80% of our outstanding shares. Of the investors we contacted, 18 expressed interest in meeting with us. We then met by phone with these investors, representing the holders of approximately 45% of our outstanding shares. These meetings were led by our Vice President Investor Relations, Securities Counsel and our Vice President Total Rewards. Our Compensation Committee Chairman, General Counsel and Chief Financial Officer participated in several of the meetings as well.

During these meetings, stockholders provided feedback on a variety of topics. In general, stockholders noted that while they were disappointed with the short term performance of the Company’s stock price, they were supportive of the leadership of our Chief Executive Officer and other NEOs. Perspectives on our executive compensation program varied across the discussions; however, the most common theme was interest in the link between pay and long-term performance, specifically with regard to our equity-based awards. Additionally, stockholders expressed interest in our adoption of certain corporate governance policies to enhance the overall executive compensation program. Stockholders appreciated the opportunity to engage in these discussions and the Company’s willingness to consider their input in designing the Company’s executive compensation program in the future. Based on this experience, we have initiated an ongoing stockholder outreach program.

The following are highlights of what we heard from our stockholders:

• Regarding Annual Equity Awards

• Consider a higher percentage of equity compensation linked to performance metrics versus time-based vesting

• Utilize a long term return on capital measure to link pay better with long term performance

• Regarding Corporate Governance Policies

• Consider the elimination of a tax gross up for the CEO in the event of a change in control

• Enhance disclosure regarding the annual goal setting process

• Provide additional detail regarding the CEO’s annual qualitative performance objectives

Changes to the Executive Compensation Program

The following outlines how we are responding to what we heard:

Equity-based award grants: Our 2014 equity grants were made in February 2014, before we gathered feedback from our stockholders. During the remainder of 2014, the Compensation Committee spent a

24

significant amount of time reviewing the advice of its independent compensation consultant and other advisors in order to carefully structure our compensation program to create an even stronger, more direct link between executive pay and performance. In 2015:

• We will discontinue annual grants of stock options for our NEOs

• We will introduce performance share units which will be earned based upon meeting long term return on capital metrics. The performance measurement period will be three years, similar to our existing performance shares which vest based upon relative total shareholder return performance.

• Our mix of long term incentive vehicles will be:

• 40% time based restricted stock;

• 25% performance shares based upon relative total shareholder return versus the S&P Building & Construction Select Industry Index over a three year period; and

• 35% performance shares based upon absolute return on capital performance over a three year period.

Change in Control Tax Gross-Up Provision: The CEO was the only executive with a gross up provision in his employment agreement, which was implemented in 2007. Based upon input from stockholders and our review of best practices, the CEO has volunteered to have this feature removed from his agreement.

We have enhanced our disclosure regarding the annual goal setting process and have provided detail regarding the CEO’s 2014 goals, as well as the Board’s assessment of the CEO’s performance in 2014.

2014 Company Performance

While challenged by an unexpectedly volatile roofing market in 2014 which impacted the Company’s overall earnings, Owens Corning maintained positive momentum in its Insulation and Composites businesses and the Company is well positioned to perform very strongly as roofing pricing and margin recover. Key accomplishments in 2014 include:

• Owens Corning continued to perform at a very high level of safety performance, with a Recordable Incident Rate of 0.56. This is slightly higher than the rate in 2013. The severity of our injuries continues to decrease. Our goal is to achieve and maintain injury-free workplaces across our Company.

• Insulation delivered its 14^th consecutive quarter of earnings before interest and taxes (“EBIT”)* improvement, earning $108 million for the year. This represents a $68 million increase over 2013, driven by improved pricing, higher volumes and strong manufacturing performance.

• Composites delivered $149 million in EBIT, a $51 million improvement over 2013 performance, driven by positive pricing trends and volume growth. Strong manufacturing performance also contributed to earnings momentum. We completed our goal in the business to achieve 75% low-delivered cost assets, by reducing high cost capacity in Japan and Canada, and avoiding capital expenditure associated with rebuilds in other areas.

^*  Please see Footnote 2—Segment Information, in our 2014 Annual Report on Form 10-K for further information on EBIT as a measure of business performance.

Executive Compensation Practices

We continually monitor the evolution of compensation best practices. Some of the most important practices incorporated into our program include the following:

• Review of Pay versus Performance. The Committee continually reviews the relationship between compensation and Company performance.

• Median Compensation Targets. All compensation elements for our executives are targeted at the median of our competitive marketplace for talent.

• Rigorous Performance Metrics. The Committee annually reviews performance goals for our annual and long-term incentive plans to assure the use of challenging, but fair targets.

• Clawback of Compensation. We have an appropriate clawback policy to allow us to recoup monies paid due to executive misstatements/misconduct.

• Meaningful Share Ownership Guidelines. Our share ownership requirements are rigorous: six times base salary for the CEO, two or three times base salary for other NEOs.

• No Hedging. Owens Corning does not allow directors and NEOs to enter into short sales of common stock or similar transactions where potential gains are linked to a decline in the price of our shares. Recipients of equity awards also may not enter into any agreement that has the effect of transferring or exchanging any economic interest in an award for any other consideration.

• No Repricing. Stock option exercise prices are set to equal the grant date market price and may not be reduced or replaced with stock options with a lower exercise price.

• Market-Competitive Retirement Programs. We eliminated defined benefit pensions for salaried employees hired after January 1, 2010 and froze existing salaried pension benefits to future accruals at the same time. Our NEOs participate in the Company’s 401(k) plan and are eligible for a Company match on amounts in excess of statutory limits.

• No Perquisites. Our NEOs participate in the same benefit plans as our salaried employees, with no special executive perquisites.

• Restrictive Covenants. Our NEOs must adhere to restrictive covenants upon separation from Owens Corning, including non-compete, non-solicitation and non-disclosure obligations.

• No Tax Gross-Ups. Parachute excise tax reimbursements and gross-ups will not be provided in the event of a change-in-control.

• Review of Compensation Peer Group. Our compensation peer group is reviewed regularly by the Committee and adjusted, when necessary, to ensure that its composition remains a relevant and appropriate comparison for our executive compensation program.

• Review of Committee Charter. The Committee reviews its charter annually to consider the incorporation of best-in-class governance practices.

How We Make Compensation Decisions

Our Executive Compensation Philosophy

The Committee believes that executive compensation opportunities must align with and enhance long-term stockholder value. This core philosophy is embedded in all aspects of our executive compensation program and is reflected in an important set of guiding principles. We believe that the application of these principles enables us

26

to create a meaningful link between compensation outcomes and long-term, sustainable growth for our stockholders.

Guiding Principles

Pay for performance	Stockholder alignment	Long-term focus
A substantial majority of pay is variable, contingent and directly linked to Company and individual performance.	The financial interests of executives are aligned with the long-term interests of our stockholders through stock-based compensation and performance metrics that correlate with long-term shareowner value.	For our most senior executives, long-term stock-based compensation opportunities will significantly outweigh short-term cash-based opportunities. Annual objectives should complement sustainable long-term performance.

Competitiveness	Balance	Governance/Communication
Total compensation will be sufficiently competitive to attract, retain and motivate a leadership team capable of maximizing Owens Corning’s performance. Each element should be benchmarked relative to peers and the broader marketplace for executive talent.	Our compensation program is designed to be challenging, but fair. Executives should have the opportunity to earn market competitive pay for delivering expected results. As results exceed expectations (both internal and external), pay levels may increase above market median levels. If performance falls below expected levels, actual pay will fall below market median.	Feedback from stockholders is periodically solicited and factored into the design of our compensation program. Ease of communication for all constituents is a key goal for all elements of our compensation program.

Role of the Compensation Committee

The Committee, which consists of six independent directors, is responsible for overseeing the development and administration of our executive compensation program.

In this role, the Committee approves all compensation actions concerning our CEO and the NEOs.

The Committee’s other responsibilities include:

• Designing executive compensation plans and programs

• Assessing input from Owens Corning’s stockholders regarding executive compensation decisions and policies

• Reviewing and approving incentive plan targets and objectives

• Assessing each NEO’s performance relative to these targets and objectives

• Evaluating the competitiveness of total compensation for the CEO and NEOs

• Approving changes to a NEO’s compensation, including base salary and annual and long-term incentive opportunities and awards

27

The Senior Vice President, Organization & Administration, along with Owens Corning’s Human Resources staff and an independent compensation consultant, assist the Committee with these tasks.

The Committee’s charter, which sets out the Committee’s responsibilities, can be found on our website at: http://investor.owenscorning.com/Corporate-Governance/Board-of-Directors/

Role of the Compensation Consultant

The Committee retained Pearl Meyer & Partners (“Pearl Meyer” or the “Consultant”) to serve as its executive compensation consultant for 2014. While Pearl Meyer may make recommendations on the form and amount of compensation, the Committee continues to make all decisions regarding the compensation of our NEOs, subject to the review of the other independent directors.

During 2014, Pearl Meyer advised the Committee on a variety of subjects such as compensation plan design and trends, pay for performance analytics, benchmarking norms and other such matters. Pearl Meyer reports directly to the Committee, participates in meetings as requested and communicates with the Committee Chair between meetings as necessary. In 2014, Pearl Meyer attended all of our Committee meetings.

Prior to engaging Pearl Meyer, the Committee reviewed the firm’s qualifications, as well as its independence and any potential conflicts of interest. Pearl Meyer does not perform other services for or receive other fees from Owens Corning. The Committee has the sole authority to modify or approve Pearl Meyer’s compensation, determine the nature and scope of its services, evaluate its performance, terminate the engagement and hire a replacement or additional consultant at any time.

Competitive Positioning

Peer Group Benchmarking

The Committee utilizes a peer group of 13 companies as one of the inputs in assessing the competitiveness of executive compensation and the appropriateness of compensation program design. These companies are either in the building materials industry, serve related markets, or use manufacturing processes similar to Owens Corning, and have size (measured in annual sales, market capitalization or number of employees) or complexity comparable to Owens Corning. This peer group is reviewed regularly by the Committee to ensure the relevance of the companies to which we compare ourselves.

The current peer group is comprised of the following companies:

Armstrong World Industries	PPG Industries
Ball Corporation	RPM International
Lennox International	Sherwin-Williams
Louisiana Pacific	Stanley Black & Decker
Masco	USG
Mohawk Industries	Valspar Corporation
Owens-Illinois

While compensation data from the peer group serves as comparison data, the Committee supplements this information with data from compensation surveys covering general industry companies of similar size based on annual sales. This additional data, compiled by the Consultant, enhances the Committee’s knowledge of trends and market practices.

28

Compensation Benchmarks

To ensure that our compensation program is appropriately competitive, the Committee believes the Target Value of each key compensation element (base salary, annual and long term incentive opportunities) should generally align with market median practices.

Individual pay opportunities may fall above or below these targets based on the Committee’s discretion. In exercising its discretion, the Committee may consider Company and individual performance, time in job and experience, job scope, retention risk and any other factors that it determines to be relevant and consistent with program objectives.

The Committee believes the best way to ensure that executive pay corresponds to Company performance is to make certain that the actual realizable value of equity granted to an executive corresponds to the actual performance of the Company for the performance period in question. This is achieved by ensuring that compensation opportunities, when granted, correspond to the market median practices of peer companies (Target Value) and then having performance goals associated with a significant portion of the median level grant so that the award has significant value only when Company performance is at levels deemed appropriate by the Committee (Realizable Value).

The graph below compares Mr. Thaman’s Target Compensation (base salary, target annual incentive opportunity and grant date value of equity awards) with the market median and 75th percentile values provided by Pearl Meyer.

29

How We Structure Our Compensation

Principal Elements of Compensation

The following elements make up our compensation program:

Base Salary	Annual Incentive	Long-Term Incentives		Retirement
		PSUs	Restricted Shares	401(k) Savings Plan
				Savings Restoration Plan
				Non-Qualified Deferred Compensation Plan

Base Salary

To help Owens Corning attract and retain the most qualified executive talent, we provide competitive base salaries to our executives targeted at the median of competitive market practices. Each year, the Committee reviews recommendations from the CEO regarding base salary adjustments for his direct reports. The Committee has complete discretion to modify or approve the CEO’s base salary recommendations and the CEO does not participate in the Committee’s determination of his own base salary. Actual salaries will vary from the market median based on factors such as job scope and responsibilities, experience, tenure, individual performance, retention risk, external market data and internal pay equity.

Annual Incentive Compensation

Overview

Annual incentives are delivered through the annual Corporate Incentive Plan (“CIP”). Funding under the 2014 CIP for all NEO awards for the year was determined based on performance as measured against corporate and individual performance goals for the year. Incentive awards for the NEOs are allocated at 75% for corporate performance measures and 25% for individual performance measures. Award amounts for each element may be earned from 0 - 200% of targeted levels, based upon performance. The corporate component is earned based upon the achievement of pre-determined financial goals as described below.

The individual component is funded at maximum if the Company is profitable, with actual award amounts earned under the individual component being reduced from maximum and determined based upon a discretionary assessment of performance by the Committee. The Committee assesses the individual performance of the CEO, and reviews and approves the CEO’s assessment of individual performance of the other NEOs in determining CIP amounts. Awards are paid in the form of a lump-sum cash payment.

At the beginning of each year, the Committee selects the corporate performance objectives, or funding criteria, that are used to determine the funding of the corporate performance component for the annual Corporate Incentive Plan. For 2014, the Committee selected specific levels of adjusted earnings from operations before interest and taxes (adjusted EBIT).

Funding of the corporate component of the CIP can range, based on Company performance, from Threshold Funding (zero CIP funding), to Target Funding (the target CIP funding established by the Committee), to Maximum Funding (two times Target Funding). For Company performance falling between the performance levels associated with Threshold Funding and Target Funding or with Target Funding and Maximum Funding, CIP funding would fall proportionately between the corresponding funding levels. For example, for Company performance falling two-thirds of the way between the performance levels associated with Threshold Funding and Target Funding, the resulting CIP funding would fall two-thirds of the way between Threshold Funding and Target Funding.

30

Individual performance goals are established each year for the CEO by the Committee. For the remaining NEOs, the CEO and each officer establish and agree upon performance objectives which serve as the individual performance goals for that officer for the year. At the close of each year the Committee evaluates the performance of the CEO against the established performance goals, in addition to other factors described below, and determines the level of funding of the individual component of the award. Similarly, the CEO reviews performance of the other NEOs against their individual goals and based on this assessment and other factors described below, the CEO makes a recommendation to the Committee. The Committee then determines the actual payout under the individual component of the CIP based on the recommendations of the CEO.

When establishing Threshold, Target and Maximum CIP performance levels for the corporate component for 2014, the Committee used a variety of guiding principles, including:

• Target performance levels generally correspond with the results and the business objectives called for in the Board-reviewed operations plan (a comprehensive strategic business plan for the Company) for the year. Whether the target performance level can be attained is a function of the degree of difficulty associated with the operations plan.

• Threshold performance levels will be set at the minimum level of acceptable performance, which yields below market compensation, but also rewards employees incrementally for delivering value during adverse business conditions. CIP performance levels between Threshold and Target are intended to compensate employees below the targeted median, which the Committee believes is appropriate for a performance-based incentive plan.

• The Maximum performance level is also determined based on the Committee’s view of the degree of difficulty of the operations plan-the more difficult the operations plan and, therefore, the Target performance level, is to achieve, the less incremental performance (above target performance) is required to reach the Maximum.

• The Maximum performance level will be set so that it is rarely attained, with the mindset that maximum performance significantly benefits the Company’s stockholders and warrants CIP funding at or near maximum.

• CIP awards between Target and Maximum should reflect a level of performance that distinguishes the Company and its leaders, and translates into increased stockholder value.

• The Committee retains discretion to reduce awards or not pay CIP compensation even if the relevant performance targets are met.

Long-Term Incentive Compensation

We believe long term incentive opportunities should align NEO behaviors and results with key enterprise drivers and the interests of stockholders over an extended period of time.

Our long term incentive program (LTI) is an equity-based program that historically has used a combination of Restricted Stock, Stock Options and Performance Stock Units. Performance Stock Units use overlapping three-year performance cycles, with a new cycle beginning each year. For 2014 grants, performance was assessed based upon Owens Corning’s total shareholder return versus the S&P 500. As noted previously, in 2015 the mix of long term incentives was changed. Stock options were eliminated and we introduced performance share units which vest based upon pre-established return on capital metrics. For 2014 awards, the mix of LTI vehicles was as follows:

• Restricted Shares - 50%

• Stock Options - 25%

• Performance Share Units - 25%

31

Beginning in 2015, Owens Corning began utilizing the following mix of long term incentives for NEOs:

• Restricted Shares - 40%

• Performance Share Units (Return on Capital based) - 35%

• Performance Share Units (Relative TSR based) - 25%

Emphasis On “At Risk” Pay

84% of our CEO’s and 73% of our NEOs’ target compensation (i.e., base salary, target annual bonus and long-term incentives) is “at risk” compensation directly contingent on performance. Actual annual bonuses and long-term incentive awards are subject to the achievement of pre-established performance targets and designed to link directly to shareowner value. Base salary and other fixed elements of compensation are essential to any compensation program and relevant to the recruitment and retention of top talent. However, we believe that “at risk” compensation for our most senior executives should significantly outweigh base salaries.

Our 2014 compensation reflects this philosophy. The following charts illustrate the basic pay mix for our CEO and other NEOs for 2014. Note the significant portion of compensation that is “at risk.”

How We Assess Performance

Goal Setting

Annually, the Compensation Committee establishes financial, strategic and operational goals for the CEO related to three broad constituencies: stockholders, customers and employees. The CEO’s goals are generally based upon the Company’s operations plan, which is reviewed by the Board of Directors.

Stockholder goals may include specific measurements of profitability, cash flow, capital efficiency and expense management. Strategic customer and transformational goals include new sources of revenue, geographic expansion, customer channel expansion and new product development. Employee goals include succession planning for key roles, improved workplace safety, improved leadership engagement and diversity, and validation of program efficacy through external recognition.

We also believe it is important to embed compliance and risk management in all our business processes, including objective setting. The framework adopted by the Compensation Committee provides that it will consider compliance and risk management objectives in evaluating overall performance.

32

Performance Assessment

The Lead Independent Director, in conjunction with the Compensation Committee Chairman, leads the annual review of Mr. Thaman’s performance versus pre-determined performance objectives. The following table summarizes Mr. Thaman’s goals and achievement for 2014:

Objective	Result
Safety
•         Ongoing improvement in safety performance	•         Small increase in number of injuries compared to 2013, still at very low injury rates •         Improvement in injury severity •         Awarded Green Cross for Safety from American Safety Council—top safety award for U.S. industrial companies
Financial Performance
•         Deliver earnings growth consistent with guidance with strong cash conversion	•         Guided to $100 million adjusted earnings before interest and taxes (“adjusted EBIT”)* improvement, but overall adjusted EBIT was basically flat to 2013. Insulation and Composites both realized significant improvement consistent with internal expectations and external guidance. Roofing experienced an EBIT decline of $154 million, largely driven by competitive pricing actions early in the year. •         Cash conversion of approximately 80% of net income, slightly below internal goal.
Operational Performance
•         Focus on commercial execution	•         On target performance with key customers. Pricing and market share performance met expectations across most of the business portfolio and market segments. The notable exception was roofing pricing, which was weaker in response to competitive pricing actions in the first quarter. Roofing market share performance was on target in the second half of the year.
Talent
•         Execute on talent development and succession plans	•         Talent development programs continued to operate effectively. Company was named by AON Hewitt as one of the Top 25 Companies for Leaders. •         Internal talent moves and external senior-level hires were completed consistent with the plan developed through Board review of talent and succession
Corporate Strategy
•         Continue to manage corporate capital allocation consistent with creation of stockholder value. Attract and retain an investor base that matches corporate strategy.	•         Implemented a common stock dividend in the first half of 2014 •         Refinanced a portion of 2016 and 2019 bonds with a new 10-year bond reducing our annual net interest expense •         Focused capital expenditures on the cost competitiveness of Composites assets, which is now largely complete •         Improved mix of value and growth investors among the stockholder base

33

In December of each year, the CEO prepares a self review, discussing the progress made toward each of his individual goals, as well as the Company’s overall financial and operating performance. Each non-management director also completes an evaluation regarding the CEO. In his role as Lead Independent Director, Mr. Hake leads the Board’s assessment of Mr. Thaman’s performance. Mr. Thaman conducts a review for each of the other NEOs and discusses the results with the Committee.

2014/2015 Compensation Actions

Based on reviews of 2014 performance, the Compensation Committee considered potential action regarding three key compensation elements:

• Base Salary: The Committee evaluates the appropriateness of a change to the CEO’s salary based upon performance, market competitiveness, time in position, etc. The Committee approved a 2.75% salary increase for Mr. Thaman for 2015, based upon its review of market competitive practices and its view of his performance in 2014. Similarly, the Committee approved a 3.3% increase to Mr. Thaman’s base salary in 2014 based upon its review of market competitive practices and his 2013 performance.

• Annual Incentive Award—Individual Component: As previously noted, the Corporate component of the annual Corporate Incentive Plan is determined by the Company’s adjusted EBIT performance vis-à-vis pre-established goals. The component (representing 75% of the award opportunity at target) funded at 0% for 2014. The remaining 25% of the target incentive may be earned based upon Mr. Thaman’s performance versus his individual objectives. The Compensation Committee has the discretion to award from 0 - 200% of the target amount. For 2014, the Committee determined his overall award to be 25% of target, representing 0% funding of the Corporate component and 100% funding of the individual component of the award.

• Long-Term Incentive Awards: Owens Corning annually makes grants of long-term incentives (LTI) at its February Compensation Committee meeting. The Committee determines the size of the CEO’s LTI award based upon market competitive practices and its view of performance. For 2015, Mr. Thaman’s target LTI award was $4,440,000. The Committee decided to award him $4,440,000.

As the Committee determines each of these three key compensation actions, Mr. Thaman develops recommendations for the remaining NEOs. Mr. Thaman reviews his recommendations with the Committee and they have responsibility for approving them.

How We View Compensation

The Summary Compensation Table on page 46 sets forth annual compensation data in accordance with SEC requirements. This uniform format is helpful for cross-company comparisons, however, the Committee believes the SEC-mandated format does not fully represent all of its annual compensation decisions and, in particular, does not provide adequate basis for a holistic pay for performance assessment. Therefore, when reviewing compensation, the Committee uses several alternative calculation methodologies, as described in this section and summarized in the chart below:

	Summary Compensation Table	Total Direct Compensation	Average Realizable Compensation
Purpose	SEC-mandated compensation disclosure	Reflects the Committee’s compensation decisions based upon 2014 performance	Used to evaluate pay for performance alignment by comparing actual to target value over a three year period
Pay Elements	Mix of actual pay received during 2014: •         Base salary paid in 2014 •         Annual incentive received for 2014 performance •         All other compensation (Company 401(k) match) Future pay opportunities that may or may not be realized such as: •         Accounting value of equity awards (restricted shares, stock options and performance share units) granted in 2014	•         Base salary paid in 2014 •         Annual incentive received for 2014 performance •         Accounting value of equity awards (restricted shares, stock options and performance share units) granted in February 2015, reflective of 2014 performance	Average of: •         Base salary received in 2012, 2013 and 2014 •         Annual incentive received for 2012, 2013 and 2014 performance •         In -the-money value of equity awards granted in 2012, 2013, and 2014, calculated based upon the stock price as of 12/31/2014, including performance share units paid. Unvested performance share units are valued at target

Total Direct Compensation

Unlike the amounts reported in the Summary Compensation Table, total direct compensation includes only pay elements that directly reflect the Committee’s assessment of Company and individual performance for the current year. For example, the Summary Compensation Table values include the grant date fair value of long term incentive awards granted in February 2014, reflecting the Committee’s assessment of 2013 performance. Total direct compensation, however, reflects 2014 performance by including the grant date fair value of awards granted in February 2015. Other elements included in the Summary Compensation Table (e.g., changes in pension values) are outside the scope of the Committee’s annual pay decisions.

Average Realizable Compensation

The Committee does not believe that Summary Compensation Table or total direct compensation values adequately measure CEO compensation for the purpose of assessing the alignment of pay with performance. Both methods utilize estimated values for long-term incentive awards at the time of grant. As might be expected, however, estimated values can differ significantly from the actual value earned.

Therefore, the Committee also takes into consideration average realizable compensation, which measures actual salary and annual incentives earned over a three year period, combined with the in-the-money value of equity awards granted over the same period. The Committee compares this to average target total direct compensation, which is comprised of salary, annual incentive target and the grant date value of long-term incentives. The examination of realizable compensation takes into account short term Corporate and individual performance (as generally measured by the Company’s annual incentive plan) and longer-term performance (as generally measured by changes in the Company’s stock price). Realizable compensation captures the impact of Owens Corning’s current share price performance on previously granted long-term incentive awards by using the in-the-money value of these awards, rather than a grant date fair value. The in-the-money value is determined by using the company’s stock price on at the end of each three year period. This directly compares the executive’s potential benefit with the return our stockholders receive by investing in our stock over the same period. The Committee, therefore, views realizable compensation as very relevant to its assessment of our compensation program’s alignment with stockholders’ long-term interests.

The chart below compares average realizable compensation for our CEO during each of the last three years with the target value of total direct compensation over the same period. Average realizable pay is strongly correlated to Owens Corning’s cumulative total return performance. As the chart indicates, average realizable pay for the CEO decreased by more than 30% from 2012 to 2014.

Pay Decisions for Named Executive Officers (NEOs)

In this section, we review and explain the 2014 compensation decisions for each of our NEOs.

In 2014, CIP funding for Corporate Performance was based upon adjusted EBIT. The funding targets were as follows:

Corporate Incentive Plan	Threshold Funding		Target Funding		Maximum Funding
Adjusted EBIT	$	416	$	505	$	580

Actual adjusted EBIT performance in 2014 was $412 million, resulting in 0% funding of the Corporate component of the CIP.

Each of the NEO’s maximum award for the Individual Component (weighted at 25%) of the CIP is described below and is subject to downward discretion by the Committee based upon its assessment of individual performance of each NEO. Factors considered in assessing individual performance include: the performance of business or functional areas for which the individual is accountable, achievement of pre-determined goals, impact on the organization and talent development. Individual performance is based on a discretionary holistic assessment of the NEO’s overall performance. The Committee determines the CEO’s individual award based upon its assessment of the CEO’s performance for the year. For the other NEOs, the assessment is made by the

38

CEO for each NEO on an individual basis and reviewed and approved by the Committee. When assessing individual performance, the considerations by the CEO and the Committee include those referenced above when determining base salary, as well as a comparison among NEOs to determine their relative contributions to the Company’s business results-with the goal being to differentiate awards based on performance. The Committee received recommendations from the CEO, assessed his performance evaluation for each of the NEOs and applied its judgment consistent with the factors described above to review and approve the CIP payouts for each NEO for 2014. The table below summarizes each NEO’s target and actual Corporate component and maximum and actual individual component under the CIP for 2014.

	Corporate Performance				Individual Performance
	(75% Weighting)				(25% Weighting)
	Target Award		Actual Funding @ 0%		@ Max Opportunity		Actual Individual Award		Total 2014  CIP Award
Thaman	$	993,750	$	0	$	662,500	$	331,250	$	331,250
McMurray	$	281,250	$	0	$	187,500	$	117,188	$	117,188
Genis	$	313,594	$	0	$	209,063	$	156,797	$	156,797
Smith	$	252,875	$	0	$	168,583	$	118,008	$	118,008
Christy	$	203,125	$	0	$	135,416	$	67,708	$	67,708

Long-Term Incentive grants to NEOs in 2014 consisted of three separate components: (1) Restricted Stock which vests at the rate of 25% per year over a four-year period (employees in certain foreign jurisdictions receive Restricted Stock Units); (2) Stock Options, which vest at the rate of 25% per year over a four-year period; and (3) Performance Stock Units (“PSUs”) which vest at the completion of the three-year performance period and participants receive a settlement of their individual grants based on the Company’s performance against pre-established performance criteria. The actual award consists of 50% Restricted Stock, 25% Stock Options and 25% PSUs. The performance criterion used to determine the number of PSUs ultimately received by the participants is total shareholder return relative to S&P 500 companies. Entry level funding (0% payout) begins at the 25th percentile. Target funding (100% payout) is achieved at the 50th percentile. Maximum funding (200% payout) is earned at the 75th percentile. Payout is capped at 100% if TSR is negative.

As noted above, 2015 grants were made in February 2015. Stock options were eliminated from the long term incentive mix. The Company introduced performance share units based upon three-year return on capital into the LTI mix. The actual award consists of 40% Restricted Stock, 35% performance share units based upon three year return on capital performance and 25% PSUs based upon total shareholder return relative the S&P Building & Construction Select Industry Index.

39

The value of actual 2015 LTIP grants for the NEOs versus targeted levels (e.g. generally market median practices) are described below. The factors used in determining actual awards versus targeted levels were substantially similar to those individual criteria discussed above, in the “Annual Incentive Compensation” section. The stock price on the grant date was used to value all LTIP grants, together with a standard Black-Scholes value of 33% for stock options. The actual accounting charge for these awards is determined under ASC Topic 718 and may be more or less than the standardized value Owens Corning uses internally for grant size determination.

	Target 2015 LTIP		Actual 2015 LTIP Award
Thaman	$	4,400,000	$	4,400,000
McMurray	$	1,060,500	$	1,100,000
Genis	$	1,176,000	$	1,200,000
Smith	$	776,000	$	900,000
Christy	$	672,000	$	650,000

For the LTIP performance cycle beginning in 2012 and ending in 2014, funding criteria for the performance share units were based solely on the Company’s stock price performance versus the companies in the S&P 500. Over the performance period, Owens Corning’s stock performed at the 15th percentile versus the S&P 500, resulting in zero funding.

2014 NEO Total Direct Compensation

The following table summarizes the Committee’s decisions for the 2014 performance year. Unlike the Summary Compensation Table, which includes the long-term incentive awards granted in calendar year 2014, total direct compensation shown in the following table instead includes long-term incentive awards granted in February 2015, reflecting a more appropriate assessment of 2014 performance.

Further details of Mr. Dana’s 2014 compensation are included in the tables in the Executive Compensation section.

Stock Ownership Guidelines

Stock ownership guidelines for our officers and directors are designed to closely link their interests with those of our stockholders. These stock ownership guidelines provide that each NEO must own stock with a value of two to six times his or her base salary, depending on position. Officers must retain 100% of after-tax shares received through LTIP grants until the ownership guideline is met. Outside Directors are required to own shares with a value of $300,000. As of the date of this Proxy Statement, all NEOs hold stock in excess of the ownership guidelines applicable to our officers, and all Outside Directors with more than three years of tenure on the Board hold stock in excess of the ownership guidelines applicable to our directors. For further details on actual ownership, please refer to the Security Ownership of Certain Beneficial Owners and Management table on page 22.

Risk Assessment

The Committee believes that although the majority of compensation provided to NEOs is performance-based, our executive compensation programs do not encourage behaviors that pose a material risk to the Company. The design of the programs encourages balanced focus on both the short-term and the long-term operational and financial goals of the Company. The Company performed an in-depth review of all aspects of all of the Company’s global compensation programs and reviewed the results with the Compensation Committee in 2013.

Timing of Equity Awards

The Company does not have any program, plan or practice to time equity grants in coordination with the release of material, non-public information. Annual awards of restricted stock, stock options and PSUs are granted on the date of the Committee’s annual February meeting. The Company may also grant equity awards to newly-hired or promoted executives, effective on the start or promotion date.

Perquisites

The NEOs participate in the same health care, and other employee benefit programs that are generally available for all salaried employees. The Committee has eliminated executive perquisites. The Company contributes to Mr. Genis’ government-sponsored French pension, as it does for other French employees who have relocated to the United States. Mr. Genis does not participate in the Company’s 401(k) plan.

Deferred Compensation Plan

The Company maintains a nonqualified deferred compensation plan under which certain employees, including NEOs, are permitted to defer receipt of some or all of their base salary and cash incentive awards under the CIP and LTIP. Deferred amounts are credited with earnings or losses based on the rate of return of specified mutual funds and/or Owens Corning stock. In 2014, the Company did not match amounts that were deferred by participants. The deferred compensation plan is not funded, and participants have an unsecured commitment from the Company to pay the amounts due under the plan. When such payments become distributable, the cash will be distributed from general assets.

In addition, certain employees, including NEOs, may defer receipt of some or all of their stock-based awards granted under the LTIP.

We provide this benefit in an effort to maximize the tax efficiency of our compensation program. We believe that this benefit is an important retention and recruitment tool as many of the companies with which we compete for executive talent provide similar plans to their executive employees.

Post-Termination Compensation

Severance Agreements

We have entered into severance agreements with our officers, including the NEOs. These agreements were approved by the Committee. The severance agreements were adopted for the purpose of providing for payments and other benefits if the officer’s employment terminates for a qualifying event or circumstance, such as being terminated without cause as this term is defined in the severance agreements. We believe that these agreements are important to recruiting and retaining our officers, as many of the companies with which we compete for executive talent have similar agreements in place for their executive employees. Based on practices among peer companies and consistent with the interests and needs of the Company, the Committee determined an appropriate level of severance payments and the circumstances that should trigger such payments. Therefore, the severance agreements with the NEOs provide, under certain termination scenarios, up to two years of pay and benefits. The severance agreements provide for payments upon a change in control only if the individual is also terminated for

43

reasons other than cause in connection with the change in control. Payments under the severance agreements are made in cash and are paid, depending on the terms of the individual executive’s agreement, either in the form of a one-time lump-sum payment or in the same manner as the regular payroll over a 24-month period. Health care coverage provided under the severance agreements is provided in kind. Additional specific information regarding potential payments under these severance agreements is found under the heading, “Potential Payments upon Termination or Change-in-Control.”

Clawback Policy

If the Board of Directors determines that a NEO has engaged in fraud, willful misconduct, or a violation of Company policy that caused or otherwise contributed to the need for a material restatement of the Company’s financial results, the Committee will review all performance-based compensation awarded to or earned by that NEO during the respective fiscal periods affected by the restatement. This review would include cash incentive awards and all forms of equity-based compensation. If the Committee determines that performance-based compensation would have been materially lower if it had been based on the restated results, the Committee will seek recoupment from the NEO as it deems appropriate based on a consideration of the facts and circumstances, and applicable laws and policies.

Tax Deductibility of Pay

Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Tax Code”), places a limit of $1 million on the amount of compensation we may deduct in any one year with respect to any covered employee under Section 162(m).

There is an exception to the $1 million limitation for performance-based compensation meeting certain requirements. Awards pursuant to our annual incentive plan, as well as grants of PSUs and stock options pursuant to our long-term incentive plan are intended to qualify as performance-based compensation meeting those requirements so that they are fully tax deductible. Restricted stock that is subject only to time-based vesting is not generally considered performance-based under Section 162(m) of the Tax Code, and, as a result, if the portion of these awards that becomes taxable to any covered employee, when combined with base salary and other non-performance-based compensation, exceeds $1 million, these awards would not be tax deductible by the Company. Because Section 162(m) restricts the Committee to the exercise of only “negative” discretion with regard to the “Individual” component of our annual incentive plan, this component of the pool funds at maximum upon threshold levels of company profitability, and the Committee then exercises negative discretion as described above.

Disclosure of Specific Incentive Targets

With respect to both the CIP and LTIP, detail on the specific financial performance targets under these criteria for performance periods completed during the reporting period has been disclosed above. However, specific performance targets for ongoing and future performance periods are not disclosed because they are substantially based on the prospective strategic operations plans and corporate objectives of the Company, and disclosure of these prospective specific performance targets is not material to an understanding of our NEO compensation for 2014. Such performance goals do not have a material impact on the compensation actually received in, or attributable to, the 2014 reported period. As described above, and as evidenced by the targets and outcomes described for the completed performance periods for the incentive compensation plans, the performance targets selected have a degree of difficulty which the Committee considers to be challenging but achievable. The Committee establishes the goals at the beginning of the performance period at levels that reflect our internal, confidential operations plan. These goals are within the ranges of what we have publicly disclosed for completed performance periods, and accordingly require a high level of financial performance in the context of the current business climate and over the performance periods to be achieved.

(1) The amounts reflected in these columns consist of restricted stock, non-qualified stock options and equity-based performance stock units granted under the Owens Corning Stock Plan. The amounts shown reflect the aggregate grant date fair value with respect to all stock and option awards made during the year. Performance stock units granted during 2014 are reflected in the column at the full fair value based on the probable outcome of the performance criteria for the award on the grant date. The grant date values of the performance stock units at the maximum possible payout are as follows: Mr. Thaman: $2,251,470; Mr. McMurray: $523,335; Mr. Genis: $576,045; Mr. Smith: $376,500; Mr. Christy, $301,200 and Mr. Dana; $624,990. See Note 20 to the Consolidated Financial Statements included in our 2014 Annual Report on Form 10-K for a discussion of the relevant assumptions made in such valuations. For further information on the 2014 awards, see the 2014 Grants of Plan-Based Awards table below.

(2) The amounts reflected in this column generally consist of amounts of cash incentive compensation received under the CIP and the LTIP for the reporting period. The cash based LTIP for the three-year performance period beginning on January 1, 2012 and ending on December 31, 2014 did not produce a payout. Therefore, the amounts in column (g) above reflect awards under the 2014 CIP to each NEO.

(3) The amounts reflected in this column consist of the increase in actuarial value of each NEO’s pension benefits in 2014. The total accrued pension value is reflected in the Pension Benefits table below.

(4) For 2014, the amounts shown for Mr. Thaman, Mr. McMurray, Mr. Smith, Mr. Christy and Mr. Dana, represent contributions made by the Company to the qualified savings plan and cash dividends accrued on unvested restricted stock. For 2014, the amount shown for Mr. Genis represents the Company’s contribution to the Voluntary French Pension Plan on his behalf and cash dividends accrued on unvested restricted stock. The contributions for Mr. Genis were made in Euros, and the amount shown was converted to US dollars based on the December 31, 2014 exchange rate.

(5) Mr. Genis’ 2012 compensation was paid in Euros and, for purposes of this table, was converted to dollars using the exchange rate on December 31, 2012.

(6) The amount shown for 2012 reflects payments made to Mr. Genis in relation to his relocation from France to the United States.

Narrative to Summary Compensation Table and Grants of Plan-Based Awards Table

Employment, Severance and Certain Other Arrangements

During 2014, each of the NEOs participated in the Company’s compensation and benefits programs for salaried employees as described here and reflected in the tables and accompanying footnotes. Each NEO receives an annual base salary as reflected in the Summary Compensation Table above. The amount of such base salary as a component of the total compensation is established and reviewed each year by the Compensation Committee. Severance arrangements with each of the NEOs are as described below in the Potential Payments Upon Termination or Change-In-Control section of this Item.

Annual Corporate Incentive Plan (“CIP”)

Owens Corning maintains the CIP, in which all salaried employees participate, with specific Company performance criteria adopted annually. Each of the NEOs is eligible to receive annual cash incentive awards based on his or her individual performance and on corporate performance against annual performance goals set by the Compensation Committee. Under the CIP for the 2014 annual performance period, the funding measures set by the Compensation Committee were based on adjusted EBIT. Cash awards paid to the NEOs under the CIP for the 2014 performance period are reflected in Column (g) of the Summary Compensation Table and the footnote above and the range of award opportunities under the 2014 CIP is reflected in the Plan-Based Awards Table above.

Long-Term Incentive Program (“LTIP”)

Owens Corning maintains a LTIP applicable to certain salaried employees as selected by the Compensation Committee, including each of the NEOs. The plan is designed to align participant compensation with the attainment of certain longer-term business goals established by the Compensation Committee.

The plan utilizes Performance Stock Units with three-year performance cycles, adopted annually, with payouts under the program dependent upon corporate performance against performance goals set by the Company’s Compensation Committee for each cycle. The outstanding three-year cycles as of December 31, 2014 include: January 1, 2012 through December 31, 2014; January 1, 2013 through December 31, 2015; and January 1, 2014 through December 31, 2016. The LTIP for the cycle ending in 2014 did not produce a payout, as reflected in column (g) and footnotes of the Summary Compensation Table. Estimated future payouts of awards under the 2014-2016 cycle are reflected in the Plan-Based Awards Table above.

The award shown in the Plan-Based Awards Table represents the NEO’s opportunity to earn the amount shown in the “maximum” column of the table if the maximum performance goal established by the Compensation Committee at the beginning of the performance period are attained or exceeded during the performance period. In the event the maximum performance goal is not attained, then the NEOs may earn the amounts shown in the “target” column if the target level of performance is attained, or the amounts shown in the “threshold” column if the threshold level of performance is attained. Participants will earn intermediate amounts for performance between the maximum and target levels, or between the target and threshold levels, and will earn no amounts for performance at or below the threshold level.

For the performance period commencing in 2014, the LTIP award provides an award under the Owens Corning Stock Plan in three separate components: (1) Restricted Stock Awards granted under the Stock Plan as described below: recipients vest and restrictions lapse on these restricted stock awards 25% per year over four years, based upon continued tenure during the vesting period and without regard to the performance criteria; (2) Performance Stock Units awarded under the Stock Plan as described below: recipients vest in these

48

Performance Stock Units at the completion of the three-year performance period and receive a settlement of the award based on the performance of the Company against pre-established performance criteria. The Performance Stock Units are settled in Company common stock; and (3) Stock Options awarded under the Stock Plan as described below: recipients vest in these non-qualified options 25% per year over four years, based upon continued tenure during the vesting period and without regard to the performance criteria. The options expire no later than 10 years after grant.

Stock Plan

In 2013 the Company’s stockholders approved the Owens Corning 2013 Stock Plan, which replaced the Owens Corning 2010 Stock Plan. In this Notice and Proxy Statement, we refer to the stock plan in place at the relevant time as the “Stock Plan.” The Stock Plan provides for participation by employees, management and directors and authorizes grants of stock options, stock appreciation rights, stock awards, restricted stock awards, restricted stock units, bonus stock awards, performance stock awards and performance stock units. The 2013 Stock Plan document was filed in the 2013 Proxy Statement.

All grants of Restricted Stock or Restricted Stock Units, Performance Stock Units, and Stock Options, including those made as a part of the LTIP as described above are made under the Stock Plan.

(1) Refers to benefits under the Company’s Cash Balance Plan or, if greater, under the Company’s Prior Plan as discussed below.

(2) Refers to benefits under the Company’s non-qualified Supplemental Plan.

(3) Refers to benefits under the Company’s Supplemental Executive Retirement Plan.

(4) Mr. Dana had a specific individual arrangement with Owens Corning (pursuant to a written agreement with the Company) that provides a supplemental pension benefit based on Owens Corning’s pension plan formula in existence on his employment date, determined as if he had earned 1.5 years of service for each year worked, provided that he remained an Owens Corning employee for no less than 10 years following his November 1995 employment date. Mr. Dana’s individual supplemental pension arrangement as described here was frozen as of March 31, 2010.

(5) These values are calculated in accordance with requirements of the Statement of Financial Accounting Standards No. 158.

Owens Corning maintains a tax-qualified noncontributory defined benefit cash balance pension plan (the “Cash Balance Plan”) covering certain salaried and hourly employees in the United States, including each of the NEOs. The Cash Balance Plan was adopted by Owens Corning in replacement of the qualified Salaried Employees’ Retirement Plan maintained prior to 1996, which we refer to as the “Prior Plan.” The Prior Plan provided retirement benefits primarily on the basis of age at retirement, years of service and average earnings from the highest three consecutive years of service. Under the Cash Balance Plan, each year prior to January 1, 2010, eligible employees generally earned a benefit of 4% of such employee’s covered pay. This was referred to under the Cash Balance Plan as a “Pay Credit.” Covered pay was defined generally as base pay and certain annual incentive compensation amounts payable during the year. Effective January 1, 2010, the Cash Balance Plan was amended to eliminate Pay Credit accruals and was closed to new participation. Accrued benefits continue to earn monthly interest based on the average interest rate for five-year United States treasury securities. Employees with an accrued benefit under the Cash Balance

52

Plan vest in that benefit once they have completed three years of service. Vested employees may receive their benefit under the Cash Balance Plan as a lump sum or as a monthly payment when they leave the Company.

As the Company transitioned from the Prior Plan to the current Cash Balance Plan, participating employees who were at least age 40 with 10 years of service as of December 31, 1995 became entitled to receive the greater of their benefit under the Prior Plan frozen as of December 31, 2000, or under the Cash Balance Plan.

Each NEO would have been entitled to payment of their vested accrued benefit under the tax-qualified plan in the event of a termination occurring on December 31, 2014, valued as a lump-sum payable as of that date as follows: Mr. Thaman, $154,001; Mr. McMurray, $11,728; Mr. Dana, $146,988; Mr. Smith, $5,183, and Mr. Christy, $134,019. Mr. Genis does not participate in the plan.

In addition to the tax-qualified pension plan, Owens Corning maintains supplemental pension benefits, including the Supplemental Plan that pays eligible employees leaving the Company the difference between the benefits payable under Owens Corning’s tax-qualified pension plan and those benefits that would have been payable except for limitations imposed by the Internal Revenue Code. The Supplemental Plan was amended to eliminate future accruals and was closed to new participation effective January 1, 2010. The NEOs participate in both the tax-qualified pension plan and the Supplemental Plan.

Each NEO would have been entitled to payment of their vested accrued benefit under the Supplemental Plan in the event of a termination occurring on December 31, 2014, valued as a lump-sum payable as of that date as follows: Mr. Thaman, $662,097; Mr. McMurray, $1,500; Mr. Dana, $224,318; and Mr. Christy, $50,832. Mr. Genis and Mr. Smith do not participate in the Supplemental Plan.

In addition to the Supplemental Plan, Owens Corning also maintains a Supplemental Executive Retirement Plan (the “SERP”) as a supplemental pension benefit covering certain employees and NEOs who joined Owens Corning in mid-career. The SERP provides for a lump-sum payment following termination of employment equal to a multiple of the covered employee’s Cash Balance Plan balance minus the present value of retirement benefits attributable to prior employment. Although such offsets may occur upon retirement, amounts shown in the above table do not reflect any such offset.

Mr. Dana would have been entitled to payment of his vested accrued benefit under the SERP in the event of a termination occurring on December 31, 2014, in a lump-sum of $2,834,000 payable as of that date. His credited service for this benefit was frozen as of March 31, 2010, Messrs. Thaman, McMurray, Genis, and Smith do not participate in the SERP.

Nonqualified Deferred Compensation

The Company has established a Deferred Compensation Plan under which eligible officers, including the NEOs, are permitted to defer some or all of their cash incentive compensation and up to 80% of their base salary. Officers may defer compensation until their separation from the Company, or may designate a set deferral period between two and ten years. They may elect to take their distribution as a lump sum, five annual installments, ten annual installments, or a set dollar amount.

Officers may choose among mutual funds offered in the 401(k) plan, as well as Owens Corning stock, for hypothetical investment of their account. Deferred amounts are credited with earnings or losses based on the rate of return of specified mutual funds and/or the value of Owens Corning stock. In 2014, the Company did not contribute or match amounts that were deferred by participants. NEOs who do not participate have been omitted from the table.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE-IN-CONTROL

The Company has entered into certain agreements and maintains certain plans under which the Company would provide compensation to NEOs in the event of a termination of employment or a change in control of the Company. The payment and benefit levels disclosed in the table below are determined under the various triggering events pursuant to these agreements that both define what constitutes the triggering event and provides those payments that would be due upon the occurrence of such events.

Severance agreements have been executed with Messrs. Thaman, McMurray, Dana, Genis, Smith and Christy. The severance agreements in place provide, under certain termination scenarios as reflected in the table below, for the payment of an amount equal to two times base salary and annual incentive compensation amounts plus continuation of health insurance coverage for a maximum period of one year. Mr. Thaman’s previous eligibility for reimbursement with respect to certain taxes if applicable to the severance payments has been discontinued. The severance agreements provide for payments upon a change in control only if the individual is also terminated for reasons other than cause in connection with the change in control. Payments under the severance agreements are made in cash and are paid, depending upon the terms of the individual NEO’s agreement, either in the form of a one-time lump-sum payment or in the same manner as the regular payroll payments over a 24-month period. Health care coverage provided under the severance agreements is provided in-kind.

The CIP and the LTIP each contain provisions that require continued employment during the performance period in order to be eligible to receive a payout under the plans, absent a change in control. However, for death, disability or retirement which occurs during the performance period, the participant may receive a pro-rated CIP award for that performance period. CIP payments are made in one-time, lump-sum payments of cash.

The Owens Corning Stock Plan provides, under certain circumstances as described above, for acceleration of vesting of restricted stock and option awards. Accelerated vesting of outstanding restricted stock and option awards may only occur upon death, disability or a change in control.

54

The NEOs are entitled, upon or following their termination, to their accrued benefits under the SERP or the Supplemental Plan arrangements as described above. NEOs would also be entitled to the normal vested pension benefits and other vested benefits which are generally available to all salaried employees who terminate employment with the Company under various circumstances.

Upon the occurrence of any triggering event, the payment and benefit levels would be determined under the terms of the agreement. The specific definitions of the triggering events are set forth in detail in the agreements which have been filed as exhibits to prior disclosures. In addition, severance payments are paid contingent upon confidentiality, a mutual release and an agreement not to compete. Each of the retirement payments of vested accrued benefits that would have occurred upon a termination event described herein are set forth in the narrative to the 2014 Pension Benefits Table above.

(1) For Stock and Option awards, vesting is incremental over a four-year period and any non-vested portion is forfeited upon termination. Vesting on these Stock and Option awards is only accelerated in the case of death, disability, or change in control, and no options may vest earlier than one year from grant except in the case of a change in control. The value of awards at vesting is uncertain and would reflect the then current value of the Company common stock and options then vesting. The amounts reflected in the table are calculated based on the closing stock price as of December 31, 2014.

(2) Performance Stock Unit awards are not forfeited upon death or disability, but would vest in full as of the date of death or disability and payout would be determined consistent with performance only at the end of the performance period. The value of awards at the end of the performance period is uncertain and would reflect the performance against the established performance targets. For involuntary termination, voluntary termination, retirement or for termination for cause occurring before vesting, these awards would be forfeited. Payout of Performance Stock Unit awards is only accelerated in the case of a change-in-control. For this table it is assumed that Performance Stock Units would pay out at maximum for a change-in-control.

(3) Where eligible for such benefits, the amount includes both health care continuation coverage and/or outplacement services. The value of health care continuation is based on the Company’s net plan cost and the coverage category in which the executive is enrolled; this value assumes that the executive continues to pay the employee portion of the premium. The value of outplacement services assumes the maximum services available under the severance agreement. As a practical matter the actual value of such services is typically substantially less than the maximum.

(4) Upon Mr. Dana’s expected termination of employment in March 2015, he will be eligible to receive payments as detailed in the Involuntary Not-For-Cause scenario described above.

(1) Includes the cash amount of the annual retainers for service on the Board in certain Board positions for 2014.

(2) The amounts shown in this column relate to stock and deferred shares as the equity component of the directors’ retainers under the Stock Plan. The amounts shown reflect the aggregate grant date fair value with respect to all stock granted and deferred shares acquired during 2014.

(3) During 2014, directors were entitled to quarterly payments of their retainers in the form elected by them prior to the beginning of the year. Directors were permitted to choose to be paid in cash or Company stock, with a minimum 60% stock requirement. As of December 31, 2014, the aggregate number of stock awards outstanding to each director, including stock and deferred shares, were as follows: Mr. Blake, 48,999; Mr. Conde, 939; Mr. Ferguson, 40,911; Mr. Hake, 44,869; Mr. Handy, 64,488; Ms. Iverson, 41,548; Mr. Lonergan, 7,591; Mr. McMonagle, 66,254; Mr. Morris, 36,147; Mr. Neely, 38,561; Ms. Nimocks, 7,024; Ms. Seaman, 939; and Mr. Williams, 12,821.

(4) Mr. Neely retired from the Board on April 17, 2014.

(5) Mr. Conde and Ms. Seaman joined the Board effective August 4, 2014.

During 2014, the Company compensated each non-management director pursuant to a new standard annual retainer arrangement that no longer involves the payment of meeting fees. This arrangement provides for an annual retainer and annual chair retainer as approved by the Compensation Committee. Each non-management director received an annual Board retainer of $200,000. The Chair of each Committee received an additional annual retainer of $15,000. The Lead Independent Director received an additional annual retainer in the amount of $25,000. All retainers are paid in a combination of stock and cash based on the director’s election with a minimum 60% stock requirement. Stock compensation for annual retainers may be deferred for issuance to the director upon the distribution date elected in writing prior to the start of the year. The annual retainers are otherwise paid on a quarterly basis. Non-management directors receive no perquisites.

Our stock ownership guidelines provide that each non-management director must own stock with a value of $300,000. As of the date of this Proxy Statement, all non-management directors with more than three years of tenure on the Board hold stock in excess of the ownership guidelines.

57

Owens Corning established a Deferred Compensation Plan, effective January 1, 2007, under which non-management directors have been permitted to defer some or all of their cash compensation for annual retainer, annual chair retainer and meeting fees. Such deferred cash compensation will be credited to an individual account and will accrue gains or losses under notional investment funds available under the plan and as selected by the director (the available fund options include a fund indexed to Company common stock). The Company does not contribute, nor does it match, any amounts deferred by directors.

PROPOSAL 2

RATIFICATION OF THE SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board of Directors has selected PricewaterhouseCoopers LLP to serve as our independent registered public accounting firm for 2015, subject to ratification by our stockholders.

Representatives of PricewaterhouseCoopers LLP will be present at the Annual Meeting to answer questions. They also have the opportunity to make a statement if they desire to do so.

We are asking our stockholders to ratify the Audit Committee’s selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2015. Although ratification is not required by our Bylaws or otherwise, the Board has submitted the selection of PricewaterhouseCoopers LLP to our stockholders for ratification because we value our stockholders’ views on the Company’s independent registered public accounting firm and as a matter of good corporate practice. In the event that our stockholders fail to ratify the selection, it will be considered a direction to the Board of Directors and the Audit Committee to consider the selection of a different firm. Even if the selection is ratified, the Audit Committee in its discretion may select a different independent public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and our stockholders.

The Board of Directors and the Audit Committee recommend a vote FOR the ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2015.

PROPOSAL 3

ADVISORY VOTE TO APPROVE 2014 NAMED EXECUTIVE OFFICER COMPENSATION

The Company is presenting the following proposal, which gives stockholders the opportunity to cast a non-binding vote on the approval of the 2014 compensation of our named executive officers by voting for or against the resolution below. This resolution is required pursuant to Section 14A of the Securities Exchange Act of 1934, as amended. Consistent with the preference expressed by our stockholders, the Company will hold this advisory vote on an annual basis until the next non-binding vote on the frequency with which advisory votes on the approval of named executive compensation should be held.

In considering your vote, we encourage you to review the Compensation Discussion and Analysis section in this Proxy Statement. The Company believes its compensation philosophy and programs are strongly linked to performance and results and appropriately aligned with the interests of stockholders.

• Compensation opportunities are generally competitive with market median practices. Actual compensation levels may exceed target levels to the extent Company and individual performance exceeds expectations. In the event performance is below targeted levels, actual pay levels may be below target levels.

• A significant majority of total compensation is performance-based.

• Executives are appropriately focused on achieving annual financial and operational goals through the Company’s annual Corporate Incentive Plan and on maximizing stockholder value over the long term, through grants of restricted shares, stock options and performance share units.

Accordingly, the Company is asking stockholders to vote FOR the following resolution at the Annual Meeting:

“RESOLVED, that the Company’s stockholders approve, on an advisory basis, the 2014 compensation paid to the Company’s named executive officers, as disclosed in the Proxy Statement pursuant to the compensation disclosure rules of the U.S. Securities and Exchange Commission, including the Compensation Discussion and Analysis, compensation tables and narratives and any related disclosure in the Proxy Statement.”

While our Board of Directors and Compensation Committee intend to carefully consider the stockholder vote resulting from the proposal, the final vote will not be binding and is advisory in nature.

The Board of Directors recommends that you vote FOR approval, on an advisory basis, of the 2014 compensation of our named executive officers.

REQUIREMENTS, INCLUDING DEADLINES, FOR SUBMISSION OF PROXY PROPOSALS, NOMINATION OF DIRECTORS AND OTHER BUSINESS OF STOCKHOLDERS

Under the rules of the SEC, if a stockholder wants us to include a proposal in our Proxy Statement and form of proxy for presentation at our 2016 Annual Meeting of Stockholders, the proposal must be received by us at our principal executive offices at One Owens Corning Parkway, Toledo, Ohio 43659 by November 13, 2015. However, in the event that we hold our 2016 Annual Meeting of Stockholders more than 30 days before or 30 days after the one-year anniversary date of the 2015 Annual Meeting, we will disclose the new deadline by which stockholder proposals must be received under Item 5 of our earliest possible Quarterly Report on Form 10-Q or, if impracticable, by any means reasonably calculated to inform stockholders. The proposal should be sent to the attention of the Secretary of the Company.

Under our Bylaws, and as permitted by the rules of the SEC, certain procedures are provided that a stockholder must follow to nominate persons for election as directors or to introduce an item of business at an Annual Meeting of Stockholders. These procedures provide that for nominations of director nominees and/or another item of business to be properly brought before an Annual Meeting of Stockholders, a stockholder must give timely notice of such nomination or other item of business in writing to the Secretary of the Company at our principal executive offices and such other item of business must otherwise be a proper matter for stockholder action. If you are a stockholder and desire to introduce a nomination or propose an item of business at our 2015 Annual Meeting of Stockholders, you must deliver the notice of your intention to do so:

• not earlier than December 18, 2015 and not later than January 17, 2016 if the date of the 2016 Annual Meeting is held within 30 days before or 60 days after the first anniversary of this year’s Annual Meeting;

• if the date of the 2016 Annual Meeting is more than 30 days before or more than 60 days after the first anniversary of the date of this year’s Annual Meeting, not earlier than the 120th day prior to the date of the 2016 Annual Meeting and not later than the later of the 90th day prior to the date of the 2016 Annual Meeting and the 10th day following the day on which a public announcement of the date of the 2016 Annual Meeting is first made by the Company; or

• in the event that the number of directors to be elected to the Board of Directors is increased and there is no public announcement by the Company naming all of the nominees for director or specifying the size of the increased Board of Directors by January 7, 2016 only with respect to nominees for any new positions created by such increase, not later than the 10th day following the day on which such public announcement is made by the Company.

These time limits also apply in determining whether notice is timely for purposes of SEC rules relating to the exercise of discretionary voting authority. If we do not receive timely notice, or if we meet other SEC requirements, the persons named as proxies in the proxy materials relating to the meeting will use their discretion in voting at the meeting.

The Board is not aware of any matters that are expected to come before the 2015 Annual Meeting other than those referred to in this Proxy Statement. If any other matter should come before the Annual Meeting, the persons named as proxies intend to vote the proxies in accordance with their best judgment.

The chairman of the Annual Meeting may refuse to allow the transaction of any business, or to acknowledge the nomination of any person, not made in compliance with the foregoing procedures.

Whether or not you plan to attend the Annual Meeting, your vote is important. Please vote on the Internet, by telephone or by mail.
