In 2021, like in previous years, the NSF continued to launch initiatives aimed at addressing some of the most pressing challenges facing society today. These challenges include but are not limited to climate change, public health, sustainable energy, and the rapid evolution of technology and its societal implications. While I couldn't find specific information on an "NSF 347" for 2021, it's clear that any initiative or document from the NSF during this time would reflect these overarching themes.
NSFS 347 2021 applies to nonmetallic gaskets made from:
Non-compliance with NSFS 347 2021 can have severe consequences, including: nsfs 347 2021
establishes a comprehensive framework for assessing the environmental and social impacts of single-ply roofing membranes throughout their entire life cycle . This standard enables architects, specifiers, and building owners to identify roofing products that meet rigorous, third-party verified sustainability criteria. 1. Introduction to NSF/ANSI 347
Tests long-term performance across different climate zones. In 2021, like in previous years, the NSF
Depending on the total number of points scored across the five pillars, a roofing membrane is awarded one of four sequential certification levels: Certification Level Requirements Meets all mandatory prerequisites Silver Meets prerequisites + minimum optional point threshold Gold Meets prerequisites + intermediate optional point threshold Platinum Meets prerequisites + highest tier of optional points
The NSF/ANSI 347-2021 standard bridges the gap between commercial roofing performance and environmental responsibility. By validating everything from raw material sourcing to long-term roof durability, it ensures that the protective barrier over a building contributes positively to global sustainability goals. NSFS 347 2021 applies to nonmetallic gaskets made
Meets all baseline prerequisite criteria for sustainability.
For architects and building professionals, NSF/ANSI 347 simplifies the complex task of specifying sustainable roofing. Instead of evaluating a plethora of environmental claims, specifiers can rely on the NSF mark to indicate a product that has been rigorously vetted against a national standard. This reduces risk and liability associated with greenwashing and ensures that specified products meet clear, performance-based criteria for sustainability.
Ensures the material performs over a long operational lifespan across varying climate zones, reducing the frequency of total roof replacements.
