By definition, NSF/ANSI 347 represents "an assessment to determine the Sustainability for Single Ply Roofing Membranes. It is the first standard for evaluating and certifying sustainable attributes of single-ply roofing membranes over their entire life cycle." Several factors are taken into consideration such as product design, manufacturing, membrane durability, corporate governance, and overall innovation.

Duro-Last has maintained a long-standing pledge to sustainability. They have 7 different membranes that have received certifications at either the platinum or gold levels!
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.
In addition, Duro-Last manufactures any excess materials into resilient flooring, walkway pads, and concrete expansion joints. Duro-Last has recycled more than 80 million pounds of PVC material through sustainable manufacturing operations and the Recycle Your Roof program.
