PROXY STATEMENT

To the Shareholders of
International Aluminum Corporation

Your proxy, in the form enclosed, is solicited by the Board of Directors of the Company for use at the Annual Meeting of Shareholders to be held on October 26, 2006, and at any postponement or adjournment thereof, for the purposes described in the accompanying Notice of Annual Meeting and in this Proxy Statement.

It is anticipated that this Proxy Statement, together with the accompanying proxy, will first be mailed on or about September 25, 2006 to the Company’s shareholders.

Record Date and Outstanding Shares

Shareholders of record at the close of business on September 8, 2006 are entitled to receive notice of, and to vote at, the meeting. There were 4,305,338 shares of common stock outstanding as of the record date.

Quorum and Voting

The presence, in person or by proxy, of the holders of a majority of the outstanding shares of the common stock as of the record date is necessary to constitute a quorum for the transaction of business at the meeting.

Shareholders are entitled to one vote for each share of common stock held on the record date on each matter to be presented for consideration and action by the shareholders, except that shareholders may cumulate their votes as to the election of directors. Cumulative voting means that each shareholder may cast a total number of votes equal to seven (i.e., the number of directors to be elected at the meeting) multiplied by the number of shares owned by the shareholder as of the record date. This total number of votes may be cast for one nominee, may be divided equally among the seven nominees or may be divided among two or more of the nominees in any manner the shareholder chooses. A shareholder is entitled to cumulate votes, however, only with respect to nominees whose names are placed in nomination prior to voting and only if the shareholder, prior to the voting, gives notice of his intention to cumulate votes. If any shareholder gives such notice, all shareholders may cumulate their votes.

Except as to the election of directors, approval of the matters to be considered at the meeting will require the affirmative vote of a majority of the outstanding shares of common stock represented and voting at the meeting, provided that such shares constitute at least a majority of the required quorum for the meeting. As to the election of directors, nominees receiving the highest number of votes, up to the number of directors to be elected, will be elected at the meeting.

Proxies

Unless revoked, all shares represented by a properly executed proxy received in time for the meeting will be voted by the proxy holders in accordance with the instructions specified in the enclosed proxy card. If no instruction is specified on a proxy with respect to any proposal to be acted upon, the shares represented by proxy will be voted “FOR”:

· the election of the seven director-nominees named herein.

· ratification of the selection of PricewaterhouseCoopers LLP as the independent registered public accounting firm for the Company.

In the event that there should be cumulative voting in the election of directors, unless otherwise specifically instructed, the proxy holders intend to distribute the total number of votes represented by each proxy among the director-nominees in such proportion as they see fit. Although the Company does not presently know of any other business to come before the meeting, if any other business should properly come before the meeting, the persons named in such proxy will vote thereon in accordance with their best judgment.

A shareholder executing and returning a proxy may revoke it any time before it has been voted by any of the following means:

· Giving written notice of revocation to the Secretary of the Company.

· Appearing in person and voting at the meeting.

· Submitting to the Secretary of the Company a duly executed proxy bearing a later date.

Abstentions and Broker Non-Votes

Abstentions will be included in determining the number of shares present at the meeting for the purpose of determining the presence of a quorum for the transaction of business, and will have the same effect as a vote against proposal 2. If a broker, bank, custodian, nominee or other record holder of shares of common stock indicates on a proxy that it does not have discretionary authority to vote certain shares on a particular matter, which is known as a broker non-vote, those shares also will be counted for purposes of determining the presence of a quorum and have the same effect as a vote against proposal 2. Abstentions and broker non-votes will not affect the outcome of the voting as to the election of directors.

PROPOSAL 1 – ELECTION OF DIRECTORS

The By-Laws of the Company provide for seven directors. Each of the nominees has indicated his or her willingness to serve as a director if elected at the meeting. If any one or more of such nominees should for any reason be unavailable to serve, the proxy holders will vote for a substitute nominee at their discretion. Proxies received cannot be voted for a greater number of persons than the number of nominees named below.

The Company and its management are dedicated to exemplary corporate governance. In August 2004, the Company adopted the International Aluminum Corporation Code of Business Conduct and Ethics.

A copy of the Code can be found at the Company’s website at www.intlalum.com.

Board Independence

The Board of Directors has determined that each of the Company’s directors, except for Messrs. Vanderstar and Rudy, who serve as executive officers of the Company, and Mr. Treinen, who served as an executive officer until his retirement in June 2005, are independent under the NYSE listing standards. Each of the Nominating and Governance, Audit and Compensation Committees of the Board of Directors is composed entirely of independent directors. In making the independence determinations, the Board reviewed director relationships with the Company as set forth in director responses to inquiries regarding employment, business, compensation and other relationships with the Company and its management.

THE BOARD OF DIRECTORS

The business affairs of the Company are managed by and under the direction of the Board of Directors, although the Board is not involved in day-to-day operations. The Board currently has three standing committees: Nominating and Governance Committee, Compensation Committee and Audit Committee, each of which is governed by a charter adopted by the Board of Directors. Each committee charter may be found on the Company’s website at www.intlalum.com. Copies of each may be obtained, without charge, upon request by writing to International Aluminum Corporation, 767 Monterey Pass Road, Monterey Park, California 91754, Attn: Corporate Secretary. Each of the committees is comprised entirely of non-employee directors deemed independent under the NYSE listing standards.

During the fiscal year ended June 30, 2006, the Board held seven meetings. The Audit Committee held four meetings, the Compensation Committee held three meetings and the Nominating and Governance Committee met one time during fiscal 2006.

Each director attended at least 75% of the aggregate of (i) the total number of meetings of the Board held during the fiscal year, and (ii) the total number of meetings held by all committees of the Board on which he served.

Executive Sessions of the Board

Non-management directors meet periodically in executive session without any members of management being present and the chair of one of the Board’s committees, on a rotating basis, presides over such sessions.

Policy Regarding Attendance at Annual Meeting

We encourage, but do not require, our Board members to attend the annual meeting of shareholders. Last year, all of our directors attended the annual meeting of shareholders.

Directors’ Compensation

Directors who are full-time employees of the Company receive no additional compensation for serving as directors. Mr. Vanderstar, in his capacity as the Chairman of the Board of Directors, is not an employee and received during fiscal 2006 an annual retainer of $150,000, paid quarterly. Other non-employee directors during fiscal 2006 received an annual retainer of $28,000, paid quarterly, plus a fee of $1,000 for chairing or $500 for attending each meeting of the Board or a committee of the Board, either in person or by telephone. In addition to meeting fees, the Audit Committee Chair received an annual retainer of $12,000 and the other Audit Committee members received an annual retainer of $8,000, in each case paid quarterly.

In fiscal 2007, the Chairman of the Board will receive an annual retainer of $150,000, paid quarterly. Non-employee directors during fiscal 2007 will receive an annual retainer of $28,000, paid quarterly, plus a fee of $1,500 for chairing or $1,000 for attending each meeting of the Board or a committee of the Board, either in person or by telephone. In addition to meeting fees, the Audit Committee Chair will receive an annual retainer of $20,000 and the other Audit Committee members will receive an annual retainer of $8,000, in each case paid quarterly.

Nominating and Governance Committee

Members:

Joel F. McIntyre, Chairman
Alexander L. Dean
John P. Cunningham

The Nominating and Governance Committee is responsible for identifying and reviewing the qualifications of nominees for Board membership, including nominees recommended by shareholders. The Committee also recommends to the Board appointees to each committee of the Board and the slate of director-nominees for election at the Company’s annual meeting of shareholders, as well as qualified individuals to fill vacancies, if any, which may occur between annual meetings.

The Committee has not established any specific qualifications for director candidates or any specific qualities or skills that a candidate must possess in order to be considered qualified to be nominated as a director. The Committee’s recommendations are based upon its evaluation of the Company’s needs at the time nominees are considered and may vary according to the particular areas of expertise being sought as a complement to the existing Board composition. In making its nominations, the Nominating and Governance Committee generally considers, among other things, an individual’s business experience, industry experience, financial background, breadth of knowledge about issues affecting the Company and time available for meetings and consultation regarding the Company’s matters.

The Nominating and Governance Committee reviews the Company’s governance policies and business practices on a continuing basis, as well as the adherence by directors and senior officers to the Company’s Code of Business Conduct and Ethics.

A copy of the Nominating and Governance Committee Charter and the Corporate Governance Guidelines may be found on the Company’s website at www.intlalum.com. All of the Nominating and Governance Committee members meet the independence requirement of the NYSE listing standards.

Any shareholder nominations must comply with the requirements of our By-Laws and should be addressed to International Aluminum Corporation, 767 Monterey Pass Road, Monterey Park, California 91754, Attn: Corporate Secretary.

Audit Committee

Members:

Norma A. Provencio, Chair
Joel F. McIntyre
Alexander L. Dean

The functions of the Audit Committee and its activities during fiscal 2006 are described below under the heading “Audit Committee Report.” The Board has confirmed that each member of the Audit Committee is independent within the meaning of the NYSE listing standards governing audit committees. Each committee member is financially literate and able to understand financial statements. Its Chairman, Norma Provencio, satisfies the definition of audit committee expert as set out in Item 401(h) of Regulation S-K. The Committee functions pursuant to the Audit Committee Charter which was adopted in fiscal 2003 and amended in August 2004. A copy of the charter may be found on the Company’s website at www.intlalum.com.

AUDIT COMMITTEE REPORT

The following Audit Committee Report does not constitute soliciting material and should not be deemed filed or incorporated by reference into any other Company filing under the Securities Act of 1933 or the Securities Exchange Act of 1934, except to the extent the Company specifically incorporates the Report by reference therein:

The Audit Committee operates under a written charter adopted by the Board of Directors. The Audit Committee’s primary duties and responsibilities are:

· reviewing with the independent registered public accounting firm the Company’s annual financial statements, including the Company’s disclosures under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s Form 10-K to be filed with the Securities and Exchange Commission, and recommending to the Board of Directors whether the financial statements should be included in the Form 10-K.

· reviewing with the independent registered public accounting firm the quarterly financial statements prior to the filing of the Company’s Form 10-Q, including the results of the independent registered public accounting firm review and the Company’s disclosures under “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

· approval of all audit engagement fees and the pre-approval of all audit and permitted non-audit services to be provided by the independent registered public accounting firm.

The Audit Committee provides assistance to the Board of Directors in fulfilling its oversight responsibility to shareholders, the investment community, and others relating to the Company’s financial statements and the financial reporting process, the systems of internal accounting and financial controls, and the annual independent audit of the Company’s financial statements. The Audit Committee has the sole authority (subject, if applicable, to shareholder ratification) to appoint or replace the Company’s independent registered public accounting firm.

The Audit Committee must pre-approve all audit services and all permitted non-audit services to be provided by the Company’s independent registered public accounting firm. In general, the Audit Committee’s policy is to grant such approval where it determines that the non-audit services are compatible with maintaining the accounting firm’s independence and there are cost or other efficiencies in obtaining such services from the independent registered public accounting firm as compared to other possible providers.

In performing its functions, the Committee acts in an oversight capacity. In this oversight role, the Committee relies on the work and assurances of the Company’s management, which has the primary

responsibility for the Company’s financial statements and reports, and on the Company’s independent registered public accounting firm which, in their report, express their opinion on the conformity of the annual financial statements with generally accepted accounting principles. In discharging its oversight role, the Audit Committee is empowered to investigate any matter brought to its attention, with full access to all of the Company’s books, records, facilities and personnel, and to retain its own legal counsel and other advisers as it deems necessary or appropriate.

In connection with the Company’s consolidated financial statements for the fiscal year ended June 30, 2006, the Audit Committee has:

· reviewed and discussed the audited financial statements with management and with representatives of PricewaterhouseCoopers LLP, the Company’s independent registered public accounting firm;

· discussed with the independent registered public accounting firm the matters required to be discussed by Statement of Auditing Standards No. 61, as amended by Statement on Auditing Standards No. 90 (Communications with Audit Committees);

· received from the Company’s independent registered public accounting firm information regarding its independence as required by Independence Board Standard No. 1 (Independence Discussions with Audit Committees); and

· discussed with the Company’s independent registered public accounting firm its independence.

Based on the Audit Committee’s review and discussions noted above, the Audit Committee recommended to the Board of Directors that the Company’s financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2006 filed with the Securities and Exchange Commission.

Compensation Committee

Members:

Alexander L. Dean, Chairman
Joel F. McIntyre
Norma A. Provencio

The Compensation Committee recommends to the Board of Directors salary and other compensation arrangements for the senior executive officers of the Company, including the granting of stock options pursuant to the Company’s stock option plan. The Committee also reviews and makes recommendations with respect to incentive compensation plans in which senior executives are eligible to participate, including the Company’s Annual Incentive Plan. The current Compensation Committee Charter was adopted in August 2004. A copy of the charter may also be found on the Company’s website at www.intlalum.com.

COMPENSATION COMMITTEE REPORT

The following Compensation Committee Report does not constitute soliciting material and should not be deemed filed or incorporated by reference into any other Company filing under the Securities Act of 1933 or the Securities Exchange Act of 1934, except to the extent the Company specifically incorporates the Report by reference therein:

The Compensation Committee is responsible for:

· establishing compensation programs that comply with the Company’s compensation philosophy;

· determining the compensation of senior executive officers;

· administering the Company’s stock option plan; and

· administering the participation of senior executive officers in the Company’s Annual Incentive Plan.

The Committee operates under a written charter which is reviewed annually. To assist in performing its duties and to enhance its objectivity and independence, the Committee has the authority to obtain advice and seek recommendations from outside compensation consultants and to review compensation data from other companies of similar size and complexity.

The Committee is composed of three non-employee directors, all of whom are independent in accordance with the NYSE listing standards.

Compensation Philosophy

The Company’s executive compensation philosophy reflects the belief of the Board of Directors that the interests of executives should be closely aligned with those of the Company’s shareholders. As a consequence, substantially all awards of incentive bonuses and stock option grants are tied to the attainment of results that benefit the Company and its shareholders. This philosophy ensures that executives are motivated to improve the overall performance and profitability of the Company as well as any specific subsidiary or area of operation for which an individual executive is responsible.

Compensation Program

The Committee regularly reviews currently available information regarding the executive compensation programs of other companies which operate in one or more of the Company’s markets, as well as a group of comparable manufacturing companies nationwide, to ensure that the Company’s policies and practices are competitive and appropriate in light of the Company’s performance and compensation philosophy. Each executive officer’s compensation package is comprised of three principal components: (1) base salary; (2) annual incentives; and (3) stock options.

Base Salary. The Company sets executive officer base salaries at the lower end of the average range of salaries paid by United States manufacturing companies with annual revenues and operations comparable to the Company’s. The Company regularly reviews pay data available from third-party sources to determine if its base salary levels meet the Company’s objectives. A number of factors are considered in establishing base salary levels for the Company’s executive officers, including the individual’s recent performance, level of responsibility, years of service and overall competitiveness relative to comparable positions at other companies.

The Chief Executive Officer’s base salary for fiscal 2006 was $285,000, a 14% increase from the base salary established for fiscal 2005. The Chief Executive Officer’s base salary and other elements of his compensation are determined in accordance with the policies previously described herein which are applicable to all senior executives of the Company. The Company has no employment contract with the Chief Executive Officer, and during fiscal 2006 he was not entitled to any change of control, retirement, severance or deferred compensation benefits or any other employee benefits not shared by employees generally.

Annual Incentives. The executive officers and administrative employees of the Company and its subsidiaries may earn annual incentive compensation under the Company’s Annual Incentive Plan (the “Plan”). Approximately 410 employees were eligible to participate in the Plan at fiscal year end. A participant’s incentive opportunity is based on his or her tier level within the Plan. Tier incentive opportunity increases based upon an individual’s potential to affect operating profitability. The Plan’s objective is to make a portion of each such employee’s total compensation incentive-based.

Each year, the Board of Directors reviews with the Chief Executive Officer and other key management personnel the Company’s Business Plan for the ensuing year, following which the Board approves the Plan with changes deemed appropriate by the Board. Target income levels (income before interest and taxes) are developed based, in part, on competitive market data and on an assessment of past and anticipated future performance. Awards for corporate-based employees are derived from overall corporate performance. Awards to operating subsidiary employees are based on a combination of corporate, segment and individual subsidiary performance.

Under the Plan, for fiscal year 2006, eligible executive officers qualified to receive annual cash bonuses in amounts up to approximately 43% of their base salaries.

Stock Options. The Company considers periodic stock option grants to executive officers to encourage and facilitate stock ownership and to underscore the importance of enhancing shareholder value over the long term. Incentive stock options are granted at 100% (and, in some instances, 110%) of the fair market value of the underlying stock on the date of grant, thus rewarding optionees only for appreciation in the Company’s stock enjoyed by all shareholders. While all executives are eligible to receive stock options, participation in a grant, as well as the size and terms of the grants to participating executives, are contingent upon performance, level of responsibility and overall compensation. No stock options were granted in fiscal 2006.

Internal Revenue Code Limits on Deductibility of Compensation. For fiscal 2006, there was no occasion for the Compensation Committee to consider Section 162(m) of the Internal Revenue Code, which limits tax deductions of public companies on compensation to certain executive officers in excess of $1 million. Where applicable, the Compensation Committee intends to consider the effect of Section 162(m) on its compensation decisions, but it has no formal policy to structure executive compensation so as to be fully deductible for tax purposes.

Stock Options

There were no stock option exercises during fiscal 2006 by named executive officers. There also were no options granted during fiscal 2006, and no outstanding options were held by executive officers at June 30, 2006.

Equity Compensation Plan Information

The Company has a 2001 Stock Option Plan that has been approved by shareholders. As of June 30, 2006, the number of options outstanding and remaining available under the 2001 Stock Option Plan were as follows:

	Plan category	Number of securities to be issued upon exercise of outstanding options (a)			Weighted-average exercise price of outstanding options (b)			Number of securities remaining available for future issuance under equity compensation plans (excluding securities reflected in column (a) (c)
Equity compensation plan approved by shareholders			8,500	(1)		$	31.56		392,200
Equity compensation plans not approved by shareholders			—			—			—
Total			8,500			$	31.56		392,200

(1) All outstanding options were granted under the Company’s prior 1991 Stock Option Plan, which expired on August 15, 2001. Assuming that all of these outstanding options were to expire or be cancelled in the future without being exercised, the shares shown would become available for grant under the 2001 Stock Option Plan. This would increase the maximum number of shares available for future issuance under the 2001 Stock Option Plan to 400,700 shares.
