Sustainability from the top down

Sustainability has been a part of the Duro-Last® culture for more than 20 years, and we have the products to back it up. Duro-Last’s flagship membrane achieved NSF/ANSI 347 Platinum Certification – the highest certification available – and the Duro-Tuff®,  Duro-Fleece®, and Duro-Last EV membranes each earned Gold Certification.
