What is NSF/ANSI 347 for sustainable roofing?

NSF/ANSI 347 is a universal sustainability standard for single ply roofing materials including PVC, TPO and EPDM. The purpose is to eliminate green washing and use science to deterimine how sustainable a product truly is from cradle to grave. Products are rated in 5 catagories; product design, product manufacturing, membrane durability, corporate governance, and innovation. Rating levels range from compliant to platinum. Just a few of the many bases covered are use of hazardous chemicals, recycled content, endurance of the product, reflectivity, and commitment to the community.

In the spring of 2015, Duro-Last was proud to become the first single ply roofing material rated by NSF/ANSI 347. Other manufacturers are following suit. We highly recommend this standard be included in architectural design of commercial roofing projects to ensure the most sustainable, longest lasting roofing materials are being used.

To learn more about this standard view the Duro-Last university Architects Guide to Specifying Sustainable Single Ply Roofing Materials found here or schedule an in person presentation. Also available is the NSF/ANSI 347 white paper found here.
