Duro-Last is pleased to announce that it has achieved platinum 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, tan, gray and dark gray as well as 50 mil terra cotta Duro-Last membranes.
 
Duro-Last is only the second manufacturer to obtain the platinum level of certification. With the company’s Duro-Tuff, Duro-Fleece and Duro-Last EV membranes having gold certification for NSF/ANSI 347, Duro-Last has the most product lines certified in the industry.
 
“Duro-Last was excited to have most of our membrane product lines certified by this third-party standard,” said Jason Tunney, Executive Vice President and General Counsel of Duro-Last. “But we wanted to take it to the next level and achieve the highest rating possible.”
 
NSF/ANSI 347 was written by NSF International 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:
 
1.    Product design
2.    Product manufacturing
3.    Membrane durability
4.    Corporate governance
5.    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 after the announcement of the publication of Environmental Product Declarations (EPDs) for Duro-Tuff, Duro-Fleece and Duro-Last EV membranes. Duro-Last is the only roofing manufacturer to offer EPDs for single-ply roofing membranes. To read more about Duro-Last’s sustainability efforts, visit www.duro-last.com/sustainability.
