Re: Owens Corning 6.500% Senior Notes due 2016 and 7.000% Senior Notes due 2036

Ladies and Gentlemen:

We have acted as special counsel to Soltech, Inc., a Kentucky corporation (the “Kentucky Guarantor”), a wholly owned subsidiary of Owens Corning, a Delaware corporation (the “Company”), in connection with its guarantee (the “Guarantee”) of $650,000,000 aggregate principal amount of the Company’s 6.500% Senior Notes due 2016 (the “Exchange Notes due 2016”) and $550,000,000 aggregate principal amount of the Company’s 7.000% Senior Notes due 2036 (the “Exchange Notes due 2036” and, together with the Exchange Notes due 2016, the “Exchange Notes”), issued by the Company pursuant to the Indenture dated as of October 31, 2006, as amended or supplemented (the “Indenture”), among the Company, the subsidiaries of the Company described therein as guarantors (“Guarantors”) and LaSalle Bank National Association, as trustee (the “Trustee”). The Exchange Notes will be registered under the Registration Statement on Form S-4 (the “Registration Statement”) filed by the Company and the Guarantors, with the Securities and Exchange Commission (the “Commission”) on April 13, 2007, under the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations under the Act.

In rendering the opinions expressed below, we have examined and relied upon copies of the Registration Statement, the Indenture, the Guarantee, the form of Exchange Notes and the form of Notation of Guarantee (the “Notice of Guarantee”) delivered to us by counsel to the Company (the “Documents”). In such review, we have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the legal capacity of natural persons and the conformity to the originals of all documents submitted to us as copies. Without independent investigation, we have relied upon and assumed the accuracy and completeness of (i) certificates and statements of officers of the Kentucky Guarantor as to factual matters, (ii) corporate records provided to us by such officers, (iii) certificates, copies and other documents obtained from public officials, and (iv) the representations and warranties contained in the Documents as to factual matters.

We also have assumed without investigation that (i) all the Documents have been duly authorized, executed and delivered by all parties thereto other than Kentucky Guarantor; (ii) each of the Documents is enforceable in accordance with its terms against all the parties thereto (including the Kentucky Guarantor); and (iii) the Kentucky Guarantor’s execution, delivery or performance of the Guarantee will not breach, violate, conflict with or constitute a default under any agreement (other than the Indenture), contract or obligation of the Kentucky Guarantor. We have further assumed, without investigation, the receipt or making of any consent, approval, order or authorization of, and the effectiveness of any registration or filing with, any third party
