Saginaw, Mich. — Feb. 29, 2016 — Duro-Last announced that it has achieved gold certification for all membrane product lines 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 Duro-Tuff, Duro-Fleece, and Duro-Last EV membranes, in addition to Duro-Last membrane, which was certified in 2015.
With the certification of these four product lines, Duro-Last has the most roofing membrane product lines certified in the industry, underscoring the company’s commitment to sustainability and transparency.
“Duro-Last believes in the importance of sustainability,” said Jason Tunney, Duro-Last’s executive vice president and general counsel. “These third-party certifications confirm what we already know about our 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. As the sustainability business division of UL, a premier global independent safety science company that has championed progress for 120 years, UL Environment works to advance global sustainability, environmental health, and safety by supporting the growth and development of environmentally preferable products, services, and organizations.
NSF/ANSI 347 was developed by the NSF National Center for Sustainability Standards (NCSS) through a consensus-based public process with a multi-stakeholder group of participants and, according to their website, is based on life-cycle 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 Duro-Last’s membranes meet the market demand for products that comply with green building standards and codes like the Green Building Initiative’s Green Globes and the International Green Construction Code (IgCC). Product specifiers and purchasers are under pressure to find products that meet their sustainability criteria, and having the NSF/ANSI 347 certification can give them the peace of mind of specifying a third-party verified product.
Duro-Last has also published environmental product declarations (EPDs) for Duro-Tuff, Duro-Fleece, and Duro-Last EV membranes. This is in addition to the previously published EPD for Duro-Last membrane — the first product-specific PVC EPD in the North American roofing industry.
Certified by NSF International, the Duro-Last EPD reports environmental impact data which assists building contractors, architects, and designers in making more informed purchasing decisions. EPDs are increasingly used across many industries to enable product manufacturers to bring transparent environmental data to customers.
“Duro-Last is proud to publish product-specific EPDs for PVC roofing,” Tunney said. “We have always known that the Duro-Last Roofing System is a durable, flexible, serviceable, and recyclable product, and now these EPDs can give building owners and specifiers peace of mind.”
