Awards points for reclamation programs that take back old roofing material for recycling rather than disposal. Industry Impact and Certification

Gaskets are submerged in synthetic water (pH adjusted, chlorinated) at elevated temperatures for 72–168 hours. The resulting leachate is analyzed for:

This standard evaluates the entire life cycle of single-ply roofing membranes, helping architects, contractors, and building owners choose products that are environmentally responsible, durable, and sustainable. What is NSF/ANSI 347?

NSF/ANSI 347 (published 2021) is a voluntary sustainability standard and third‑party certification protocol for single‑ply roofing membranes. It sets criteria across material health, product efficiency, manufacturing, supply chain transparency, and end‑of‑life to help roof membrane manufacturers demonstrate reduced environmental and social impacts and support sustainable building rating systems. nsfs 347 2021

For AEC (Architecture, Engineering, and Construction) professionals, specifying an NSF/ANSI 347 certified roofing membrane offers immediate, practical advantages:

: Sustainable sourcing practices of baseline polymers and chemical compounds.

Achieved by industry leaders featuring optimized LCAs and highly efficient formulations. Awards points for reclamation programs that take back

NSFS 347 2021 is a national standard that provides guidelines for fire safety in buildings, structures, and premises. The standard outlines the minimum requirements for fire safety systems, equipment, and practices to ensure the protection of people and property from fire hazards. The document is designed to provide a framework for fire safety management, including prevention, detection, and suppression of fires.

Commercial building envelopes encounter considerable environmental stress, and the roof represents a significant percentage of a structure's total material volume. In the past, assessing the true sustainability profile of low-slope or flat roofing materials was challenging due to fragmented data. Manufacturers frequently claimed eco-friendly benefits based solely on single attributes, such as solar reflectance or the inclusion of recycled content.

: Total energy optimization and the utilization of renewable energy infrastructure. What is NSF/ANSI 347

This category rewards manufacturers who introduce forward-thinking technologies or processes that exceed the baseline requirements of the standard. Examples include pioneering advanced closed-loop roof recycling programs or engineering breakthrough material configurations that drastically reduce carbon footprints. Levels of Certification

Evaluates the manufacturer's corporate social responsibility, public sustainability reporting, and supply chain transparent practices.

: It establishes a consistent set of environmental, social, and economic performance metrics for the roofing industry.
