In August 2018, Duro-Last 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.
