NSFS 347 2021: Understanding Sustainable Single-Ply Roofing Standards
The standard actively awards points to manufacturers that build formal reclamation and recycling programs. This applies to both pre-consumer factory scrap and post-consumer torn-off materials at the end of a building's lifecycle, redirecting tons of high-performance polymers back into production loops. utilizing bio-based alternatives
Instead of just looking at the final product, this standard ensures that every step—including raw material sourcing and end-of-life disposal—has been considered, reducing the overall environmental footprint. Conclusion: Driving Innovation in Roofing
This category rewards pioneering advancements that push the boundaries of roofing technology. Manufacturers can earn innovation credits by developing unique recycling infrastructure, utilizing bio-based alternatives, or vastly improving solar readiness and energy mitigation profiles. 3. Certification Tiers Explained reducing the overall environmental footprint.
The standard evaluates major polymer-based single-ply roofing membranes, including: (Thermoplastic Polyolefin) PVC (Polyvinyl Chloride) EPDM (Ethylene Propylene Diene Terpolymer) KEE (Ketone Ethylene Ester) PIB (Polyisobutylene) The Core Evaluation Categories
This multi-faceted approach ensures that sustainability is considered from manufacturing to installation, encouraging best practices throughout a product's lifecycle.
