NSF/ANSI 347-2021 standard represents a critical milestone in the construction industry’s shift toward sustainable infrastructure. Specifically focused on Sustainability Assessment for Single-Ply Roofing Membranes
NSF/ANSI 347 refers to the Sustainability Assessment for Single Ply Roofing Membranes , a standard developed by NSF International. Always consult your local plumbing code, as some
Complying with NSFS 347 2021 offers several benefits to food businesses, including:
Products under review earn specific tiers of compliance depending on the total point score verified by independent auditors during on-site facility inspections. Certification Level Requirements & Market Meaning
Measures long-term performance in various climate zones, emphasizing that a longer-lasting roof reduces overall environmental impact. more resilient building practices
If you are currently preparing a sustainable building project or updating a commercial specification workflow, consider these actions:
As the commercial construction industry pivots toward greener, more resilient building practices, the demand for verified sustainable materials has grown exponentially. For architects, contractors, and building owners looking to reduce their environmental footprint, single-ply roofing systems are a critical component of the building envelope.
The keyword represents the premier international consensus standard for evaluating and certifying the sustainability profile of single-ply roofing membranes throughout their entire product life cycle. Maintained by NSF International and accredited by the American National Standards Institute (ANSI), the 2021 edition of this standard serves as a critical tool for architects, specifiers, and building owners looking to eliminate "greenwashing" and verify legitimate eco-friendly building envelope materials.
