New Accounting Standards [Abstract]
Accounting Pronouncements Recently Adopted	Accounting Pronouncements Recently Adopted In June 2011, the FASB issued ASU 2011-05, “Presentation of Comprehensive Income.” ASU 2011-05 requires the components of net income and other comprehensive income to be either presented in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. An entity is also required to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. In December 2011, the FASB issued ASU 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU No. 2011-05,” which defers the effective date for the portion of ASU 2011-05 that pertains to the presentation of reclassification adjustments out of accumulated other comprehensive income. While ASU 2011-05 changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under current accounting guidance. The Company adopted ASU 2011-05 effective January 1, 2012. As this guidance only amends the presentation of the components of comprehensive income, the adoption did not have an impact on the Company’s consolidated financial position or results of operations.
Acquisition	In 2011, the Company completed the acquisition of substantially all of the assets of Iron Deck Corporation, a manufacturer of steel deck-framing systems located in Denver, Colorado, for approximately $2 million in cash plus the assumption of certain liabilities. As a result of the acquisition, the Company recorded an increase of $3.7 million to Goodwill. The provisions of the purchase agreement allow for future payments contingent upon certain future sales targets. The contingent payments were estimated as purchase consideration at the acquisition date and may be revised if actual sales differ from projected sales. As a result of decreased near-term sales projections of steel deck-framing systems, the Company reduced its provision for future contingent payments and recorded a $1.4 million benefit to selling, general and administrative expenses in the three months ended September 30, 2012.
Financial Instruments	The Company considers the recorded value of its financial assets and liabilities, consisting primarily of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued expenses and other current liabilities to approximate the fair value of the respective assets and liabilities at September 30, 2012 and December 31, 2011.
Contract Termination Costs	Contract Termination Costs In anticipation of relocating its corporate headquarters, the Company entered into a lease agreement in 2005. The Company reconsidered and decided not to move its headquarters. The lease, which extends through June 30, 2019, obligates the Company to lease 55,047 square feet. The Company has executed subleases for the entire 55,047 square feet it currently leases. The terms of the existing subleases expire in years 2013 to 2019. The Company estimates that the present value of the estimated future sublease rental receipts, net of transaction costs, will be less than the Company’s remaining minimum lease payment obligations under its lease for the office space. Accordingly, the Company accounts for the expected shortfall as contract termination costs and has recorded a liability in accordance with FASB ASC Topic 420, “Exit or Disposal Cost Obligations.” To estimate future sublease receipts for the periods beyond the term of the existing subleases, the Company has assumed that the existing subleases will be renewed or new subleases will be executed at rates consistent with rental rates in the current subleases. However, management cannot be certain that the timing of future subleases or the rental rates contained in future subleases will not differ from current estimates. Factors such as the delivery of a significant amount of new office space or poor economic conditions could have a negative effect on vacancy rates and rental rates in the area. The inability to sublet the office space in the future or unfavorable changes to key management assumptions used in the estimate of the future sublease receipts may result in material charges to selling, general and administrative expenses in future periods.
Product Warranty	Product Warranty The Company warrants that its products will be free from material defects in workmanship and material and will not check, split, splinter, rot or suffer structural damage from termites or fungal decay. This warranty extends for a period of 25 years for residential use and 10 years for commercial use. With respect to the Company’s Transcend and Enhance product, the Company further warrants that the product will not fade in color more than a certain amount and will be resistant to permanent staining from food substances or mold (provided the stain is cleaned within seven days of appearance). This warranty extends for a period of 25 years for residential use of the Transcend product, 20 years for residential use of the Enhance product, and 10 years for commercial use of either product. If there is a breach of such warranties, the Company has an obligation either to replace the defective product or refund the purchase price. The Company continues to receive and settle claims related to material produced at its Nevada facility prior to 2007 that exhibits surface flaking and maintains a warranty reserve to provide for the settlement of these claims. Projecting future surface flaking settlement costs requires management to estimate the number of claims to be received, the number of claims that will ultimately result in payment and the average cost to settle each claim, all of which are subject to variables that are difficult to predict.

Disclosure of accounting policy for completed business combinations (purchase method, acquisition method or combination of entities under common control). This accounting policy may include a general discussion of the purchase method or acquisition method of accounting (including for example, the treatment accorded contingent consideration, the identification of assets and liabilities, the purchase price allocation process, how the fair values of acquired assets and liabilities are determined) and the entity's specific application thereof. An entity that acquires another entity in a leveraged buyout transaction generally discloses the accounting policy followed by the acquiring entity in determining the basis used to value its interest in the acquired entity, and the rationale for that accounting policy.
