SAGINAW, Mich. — Duro-Last has announced that it has achieved certifications for each of its roofing membranes under the NSF American National Standard for Sustainable Roofing Membranes – NSF/ANSI 347.

Awarded platinum certification in 2016 for all colors of the Duro-Last membrane in 40-, 50-, and 60-mil options, this certification was approved for renewal and expanded to include the Duro-Last Rock-Ply and Shingle-Ply Designer Series membranes. Additionally, the 2016 gold certification for the reflective white Duro-Tuff, Duro-Fleece and Duro-Last EV membranes was also renewed and expanded to include all colors for Duro-Tuff and Duro-Fleece, as well as the Duro-Fleece Plus membrane.

Duro-Last continues to be one of only two manufacturers to achieve the highest-level platinum certification, and now leads the industry in certified membranes under NSF/ANSI 347. As specifiers and building owners increasingly demand environmentally conscious solutions for their projects, Duro-Last’s commitment to developing and fostering high-quality, sustainable products ensures that a variety of options are available for all types of commercial roofing needs.

“Sustainable products and practices have been a priority at Duro-Last for over 20 years,” said Katie Chapman, Duro-Last sustainability specialist. “These certifications help drive our efforts to enhance sustainability within our company and throughout the industry, and keep us accountable as we continue to grow our products and services.”

NSF/ANSI 347 is the leading consensus standard for evaluating and certifying sustainable attributes of single-ply roofing membranes over their entire life-cycle. They use a 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

Duro-Last’s commitment to sustainability and environmental awareness includes a full line of bright white membranes that exceed industry standards for reflectivity, which can greatly reduce energy demand and consumption for building owners. Additionally, they published the first product-specific PVC environmental product declaration (EPD) in the commercial roofing industry; and they offer a Roof Take Back program, which recycles manufacturing scrap and aged roofing materials into resilient flooring, walkway pads, and concrete expansion joints.

“We have not only proven our commitment to sustainable products, but through our corporate culture as well,” explained Chapman. “We have removed disposable cups from all of our facilities, introduced company-wide recycling stations, and installed water bottle filling stations. We recognize that true sustainability comes from all aspects of our business, not just the products we offer, and we’re proud to be seen as a trailblazer for these efforts throughout the industry.”
