For architects and specifiers, NSF/ANSI 347 serves as a valuable tool for selecting sustainable roofing products, which can contribute points toward green building certifications like LEED. For manufacturers, certification to NSF/ANSI 347 provides an objective and transparent way to validate the sustainability of their products and differentiate themselves in the marketplace.
To earn NSF certification under the 2021 edition, a gasket must pass four battery tests:
The 2021 revision tightened several sections: nsfs 347 2021
Rewards the use of environmentally preferred materials, non-hazardous ingredients, and optimized raw material extraction.
The standard is more than a certification; it is a roadmap for the roofing industry to create better, more sustainable products. By adhering to these strict guidelines, manufacturers are encouraged to innovate in material science and production, resulting in roofing systems that are not only durable and effective but also environmentally responsible. For architects and specifiers, NSF/ANSI 347 serves as
NSFS 347 2021 is to NSF 61 – meaning a gasket can pass NSF 61 for chemical safety but still fail NSFS 347 due to poor creep resistance.
To ensure successful implementation of NSFS 347 2021, food businesses should: The standard is more than a certification; it
Measures operational efficiency, targeting waste minimization, greenhouse gas reductions, and water conservation at the factory level.
Evaluates the manufacturer's corporate social responsibility, public sustainability reporting, and supply chain transparent practices.
In the first two years of enforcement, the top reasons gaskets failed NSFS 347 2021 were:
is an American National Standard that provides a comprehensive framework to assess the sustainability profile of single-ply roofing membranes. It covers the entire life cycle of the product, from raw material extraction through manufacturing, use, and end-of-life management.
