Sustainability Standard – NSF/ANSI 347: Sustainability Assessment for Single Ply Roofing Membranes

NSF/ANSI 347, Sustainability Assessment for Single Ply Roofing Membranes, is the first standard for evaluating and certifying sustainable attributes of single-ply roofing membranes over their entire life cycle. As products with environmental claims continue to enter the marketplace, independent, third-party certification of products to national standards can help architects and specifiers make educated decisions about product selection. NSF 347 provides a standard of excellence in sustainability for the entire single ply roofing industry. It is now one of eight consensus-based sustainability standards developed through NSF for building products. It is also the first one that addresses the building envelope, carrying with it significant potential for improving building energy efficiency while positively impacting the quality of the urban environment.

NSF

NSF/ANSI 347 is one of eight consensus-based sustainability standards being developed through NSF. NSF-certified sustainable products also earn points toward the U.S. Green Building Council’s LEED Certification.

The standard employs a point system to evaluate roofing membranes in several areas, including:

  • PRODUCT DESIGN – Integration of environmental and life cycle thinking into the product design process
  • PRODUCT MANUFACTURING – Quantification of the environmental impacts from manufacturing, and actions to reduce or eliminate those impacts
  • MEMBRANE DURABILITY – Membrane physical properties, service life, and repairability
  • CORPORATE GOVERNANCE – Human rights, child labor, forced labor, employee safety and education, and community responsibility
  • INNOVATION

Manufacturers certified by NSF are authorized to use the NSF Sustainability Certified Mark on their products and in their advertising.
