SAGINAW, MICH.—Duro-Last announced that it has achieved gold certification under the NSF American National Standard for Sustainable Roofing Membranes—NSF/ANSI 347. Certified by UL, this standard represents that Duro-Last manufactures a product that is third-party verified as sustainable, durable, and high performing. The certification applies to 40, 50 and 60 mil, white, gray, dark gray, tan, and terra cotta Duro-Last membranes.
NSF/ANSI 347 was written by NSF International and, according to their website, is based on lifecycle assessment principles. NSF/ANSI 347 employs an easy-to-use point system to evaluate roofing membrane products against established prerequisite requirements, performance criteria and quantifiable metrics in five key areas: product design, product manufacturing, membrane durability, corporate governance, and innovation.
Obtaining this certification will help the Duro-Last membrane meet the market demand for products that comply with green building standards like the Green Building Initiative’s Green Globes. Product specifiers and purchasers are under pressure to find products that meet their sustainability criteria, and having the NSF 347 certification can give them the peace of mind of specifying a third-party verified product.
This certification is one more step in Duro-Last’s commitment to sustainability and transparency, coming right after the announcement of the publication of the company’s first Environmental Product Declaration (EPD).
Will Seek Certification for All Membrane Products
“Duro-Last is working hard to be a leader in our industry for both sustainability and transparency,” said Jason Tunney, Executive Vice President and Legal Counsel of Duro-Last. “This is just the beginning because we are committed to obtaining this certification for all of our membrane products.”
Duro-Last has worked with UL for many years on product testing, including the UL 790 Spread of Flame Test, UL 1256 Direct to Deck (insulation) and the UL 2218 Hail Impact Test.
