You cannot see, smell, or taste most flammable gases. In "347 work," you must use a calibrated multi-gas detector.
A roof cannot be sustainable if it fails early. This section rewards products that demonstrate exceptional durability, long service life, and operational efficiency. Features like high solar reflectance (which reduces the urban heat island effect and lowers building cooling costs) earn significant points here. 5. Corporate Governance
The standard applies to a wide range of products, including textile, vinyl, and paper-based wallcoverings used in commercial and institutional settings. The Scoring System: How It Works
The benefits of NSF 347 work include:
2. National Standards for Sustainable Drainage Systems (NSfS)
: It ensures the roof is not just "green" in name but is durable and won't end up in a landfill in 10 years.
: Rewards high solar reflectance (cool roofs) that mitigate the urban heat island effect. nsfs 347 work
: The manufacturer’s social responsibility and safety records.
The standard uses a point-based system, assigning scores across five core categories that define a product's sustainability:
Based on the total points earned (out of 123 available), a product can achieve one of four certification levels: : Minimum 35 points Silver : Minimum 45 points Gold : Minimum 56 points Platinum : Minimum 75 points You cannot see, smell, or taste most flammable gases
The standard was established by a broad coalition including manufacturers, consultants, architects, engineers, trade associations, and regulatory agencies, ensuring it is both practical and rigorous.
