Re:        4.20% Senior Notes Due 2024

Ladies and Gentlemen:

We have acted as counsel in the Commonwealth of Kentucky (“Kentucky”) to Soltech, Inc., a Kentucky corporation (the “Kentucky Guarantor”), a wholly owned subsidiary of Owens Corning, a Delaware corporation (the “Company”), in connection with the issuance and sale by the Company of $400,000,000.00 aggregate principal amount of its 4.20% Senior Notes due 2024 (the “Notes”) pursuant to the prospectus supplement dated November 4, 2014 (the “Prospectus Supplement”), which supplements the prospectus dated February 16, 2012 (the “Base Prospectus”) that forms a part of the Company’s Registration Statement on Form S-3 (File No. 333-179542) filed on February 16, 2012 (the “Registration Statement”), with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations under the Securities Act. The Notes are being issued under the Indenture (the “Base Indenture”) dated as of June 2, 2009, among the Company, the subsidiaries of the Company described therein as guarantors (“Guarantors”) and Wells Fargo Bank, National Association, as trustee (the “Trustee”), as amended and supplemented by the First Supplemental Indenture (the “First Supplemental Indenture”), dated as of June 8, 2009, among the Company, the Guarantors named as a party thereto and the Trustee, as further amended and supplemented by the Second Supplemental Indenture (the “Second Supplemental Indenture”) dated as of May 26, 2010, among the Company, the Guarantors named as a party thereto and the Trustee, as further amended and supplemented by the Third Supplemental Indenture (the “Third Supplemental Indenture”), dated as of October 22, 2012, among the Company, the Guarantors named as a party thereto and the Trustee, and as further amended and supplemented by the Fourth Supplemental Indenture (the “Fourth Supplemental Indenture”; and with the Base Indenture, the First Supplemental Indenture, the Second Supplemental Indenture, and the Third Supplemental Indenture collectively, the “Indenture”), dated as of November 12, 2014, among the Company, the Guarantors named as a party thereto and the Trustee, which Notes will be guaranteed by the Kentucky Guarantor.

In rendering the opinions expressed below, we have examined and relied upon (i) a copy of the Underwriting Agreement, dated as of November 4, 2014 (the “Underwriting Agreement”), among Goldman, Sachs & Co., J.P. Morgan Securities LLC and Wells Fargo Securities, LLC, as representatives of the Underwriters, the Company, and the Guarantors named therein (the “Guarantors”), including the Kentucky Guarantor, (ii) a copy of the Prospectus Supplement

delivered to us by the Company; (iii) a copy of the Indenture; (iv) a copy of the Articles of Incorporation of the Kentucky Guarantor, as certified by the Secretary of State of Kentucky on November 12, 2014 (the “Articles of Incorporation”), (v) a Certificate of Existence for the Kentucky Guarantor, as issued by the Secretary of State of Kentucky on October 21, 2014 (the “Certificate of Existence”); (vi) a copy of the by-laws of the Kentucky Guarantor (the “Bylaws”), as certified by the Secretary of the Kentucky Guarantor, and (vii) a copy of all proceedings, actions and resolutions of the board of directors of the Kentucky Guarantor relating to the Registration Statement, the Indenture and the issuance and sale of the Notes. 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 Underwriting Agreement as to factual matters.

We also have assumed without investigation that (i) the Registration Statement and the Indenture have been duly authorized, executed and delivered by all parties to the Registration Statement and the Indenture other than the Kentucky Guarantor and (ii) the Kentucky Guarantor’s execution, delivery or performance of the Registration Statement and the Indenture will not breach, violate, conflict with or constitute a default under any agreement (other than the Registration Statement and 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 or governmental body that is required to be received or made by any party in connection with the execution, delivery and filing of the Registration Statement or the Indenture or the consummation of the transactions contemplated thereby.

Based on the foregoing, and subject to the assumptions, qualifications and limitations set forth in this opinion (the “Opinion”), we are of the opinion that:

1. The Kentucky Guarantor is a corporation duly incorporated and validly existing under the laws of Kentucky.

2. The Kentucky Guarantor has the corporate power and authority to execute, deliver and perform its obligations under the Registration Statement and the Indenture.

3. The Kentucky Guarantor has duly authorized the (i) execution and delivery of the Indenture and (ii) performance by the Kentucky Guarantor of its obligations under the Indenture.
