With the increasing importance of green building certification systems like LEED, having independent verification for building materials is critical.

Tests long-term performance across different climate zones.

NSF/ANSI 347 takes a holistic approach, evaluating products across five crucial categories. The following table details the core components of its assessment:

Assesses the long-term performance and repairability of the membrane in various climate zones to ensure longevity. Corporate Governance: nsfs 347 2021

Rewards manufacturers for pushing the boundaries of sustainable technology. Understanding the Tiers

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

Use the standard to ensure the accuracy of sustainability claims and to meet LEED certification requirements. The following table details the core components of

Before this standard, labeling a product as "sustainable" was often vague and inconsistent. NSF/ANSI 347 was created to provide objective, measurable criteria to answer fundamental questions about a roof's environmental footprint. A roof is a building's first line of defense against the elements and a major factor in its energy efficiency. By focusing on single-ply membranes (like TPO, PVC, and EPDM), this standard directly addresses the significant potential for improving a building's energy performance and positively impacting the urban environment.

One of the most impactful features of the standard is how it incentivizes structural waste reduction. Re-roofing projects historically generate immense pressure on regional landfills.

Evaluates operational efficiency, including energy conservation, waste minimization, and water usage. Use the standard to ensure the accuracy of

To ensure compliance with NSFS 347 2021, building owners and managers should:

Using NSF/ANSI 347-certified products helps projects gain credits for green building rating systems, such as LEED, due to the standard's rigorous, comprehensive approach. Better Performance and Longevity

Social accountability, including fair labor practices, safety programs, and community investment.
