CertainTeed® Restoration Millwork® Exterior Trim Achieves GreenCircle® Certification

(Valley Forge, Pa.) – CertainTeed Corporation has achieved GreenCircle® certification for its Restoration Millwork® Exterior Trim, enhancing the sustainable appeal and environmental transparency of the product line. The third-party certification was conducted by GreenCircle Certified, LLC, and the process included a comprehensive review of the manufacturing process and products, verifying the 21 percent recycled content of the product.

“Securing an independent third-party certification of the recycled content within our Restoration Millwork products reinforces our overarching commitment to environmental responsibility,” says Rick Brinton, general manager for Restoration Millwork at CertainTeed Siding Products Group. “In addition to GreenCircle certification, the long-lasting performance and durability of Restoration Millwork make it an ideal choice for sustainable building projects.”

In order to verify and certify recycled content claims, GreenCircle conducted a detailed evaluation of the Restoration Millwork product line and the company’s manufacturing operations in Social Circle, Ga. The claims were verified for conformance with International Organization for Standardization (ISO) 14021 Environmental Labels and Declarations requirements.

“The marketplace is full of misleading and confusing claims about the environmental performance of building products,” said Tad Radzinski, co-founder of and certification officer for GreenCircle. “Through GreenCircle certification, CertainTeed has validated the legitimacy of the environmental claims behind Restoration Millwork and is strengthening its commitment to product transparency.” News Release Restoration Millwork GreenCircle –Page 2 of 3

Made from cellular polyvinyl chloride (PVC), the full line of Restoration Millwork trim, beadboard and accessories is engineered to look, feel and work like top-grade lumber. Unlike wood, however, it is made with a long-lasting, low-maintenance material that is resistant to rotting, warping, moisture and insects. It can be cut using ordinary woodworking tools and fastened with nails or screws. It is highly resistant to yellowing caused by UV rays, resists freezing during winter months, features a Class A (Class 1) flame spread classification and is backed by a 25-year limited warranty.
