The final category rewards forward-thinking manufacturers who go beyond the standard's baseline requirements. The innovation category provides points for advancements that drive sustainability forward, such as the development of new, less impactful materials, novel recycling processes, or unique design features that enhance environmental performance. This encourages continuous improvement and pushes the entire roofing industry toward more creative and effective solutions.
Sustainability is synonymous with durability. A wallcovering that lasts ten years is far better for the environment than one that needs replacing after three. This category focuses on the product’s service life, maintenance requirements, and the manufacturer's ability to provide clear installation and care instructions to ensure longevity. End-of-Life Management
This category examines how the roofing membrane is formulated. Points are awarded for maximizing the use of recycled content (both pre-consumer and post-consumer), using bio-based materials, and designing the product for easy disassembly or recycling at the end of its useful life. 2. Product Manufacturing
Mistaking this standard can be fatal. Work under NFPA 347 (let’s call it "347 work") involves ignition sources—torches, grinders, arc welders—located near flammable liquids, vapors, or dust. nsfs 347 work
Auditors look closely at the environmental footprint of the production plants. This includes measuring and reducing: Greenhouse gas emissions Total energy consumption Water usage
Verify that the materials do not leach toxins into surrounding fluid systems. This is especially vital for equipment touching public water systems or marine habitats.
For "NSFS 347 work," standard work boots are insufficient. Sustainability is synonymous with durability
The standard uses a point-based system to rate products based on five key areas of focus. To achieve certification, a manufacturer must meet certain prerequisites and then earn points across the following categories:
Elias inspected the clash. It was a common headache in retrofit work. The standard dictated specific clearances to allow for movement without buckling. If they forced the track, the first time the wind swayed the building, the wall would pop screws.
For architects, specifiers, and facilities managers, a roof engineered to meet this certification represents a major leap forward in sustainable design. Understanding how NSF/ANSI 347 works empowers building professionals to select verified, high-performance materials that align with modern environmental benchmarks. What is NSF/ANSI 347? manufacturers must first meet mandatory prerequisites
Based on the number of points earned, products are rated as Certified, Silver, Gold, or Platinum . Architects often use these certifications to earn LEED v4.1 points for green building projects. 2. 347V Electrical Systems (NSF Certified Fixtures)
To achieve any level of certification, manufacturers must first meet mandatory prerequisites, including having a documented plan for sustainable design. Ratings are then awarded based on total points earned: Certification Level Points Required Conformant 35 – 44 points 45 – 55 points 56 – 74 points 75+ points Industry Significance NSF/ANSI 347 - Duro-Last
