Rewards manufacturers for implementing new technologies or reclamation processes that exceed current standard requirements. Certification Levels
: Sustainable sourcing practices of baseline polymers and chemical compounds.
If you are interested in learning more about the technical details of the certification, or comparing manufacturers, I can help you find specialized information regarding specific membrane types (EPDM, TPO, PVC) that meet these requirements. Share public link nsfs 347 2021
Many professionals confuse NSFS 347 with NSF/ANSI 61 (the broader drinking water components standard). The key differences:
The commercial construction sector relies on certifications to eliminate "greenwashing"—the practice of making unverified environmental claims. The updated prior frameworks by aligning more closely with modern global data standards and emphasizing material circularity.

The NSF/ANSI 347 standard provides a rigorous framework for architects, specifiers, and building owners to identify roofing products with reduced environmental impacts. The 2021 version represents the latest consensus-based updates from the NSF Joint Committee on Sustainable Single Ply Roofing . Key Evaluation Criteria

is the premier American National Standard for evaluating and certifying the sustainability of single-ply roofing membranes across their entire product life cycle . In the architecture, engineering, and construction (AEC) industry, the NSF/ANSI 347 protocol serves as the primary multi-attribute benchmark. It allows manufacturers to substansiate their environmental, social, and economic sustainability claims through rigorous, independent third-party validation.
NSFS 347 would likely have trained students to think in networks—nodes, feedback loops, delays—rather than in silos. That’s not glamorous, but it’s urgent: employers in government, NGOs, and private industry increasingly want people who can translate between disciplines, build coalitions, and design interventions that work in messy contexts.
This pillar evaluates the chemical composition and sourcing of raw materials used in the membrane. Points are awarded for maximizing the use of recycled content (both pre-consumer and post-consumer). It also assesses the formula's optimization to reduce or completely eliminate hazardous chemical additives, optimizing the product for end-of-life recycling without contaminating the recycling stream. 2.
