Based on total points, the product receives one of four rating levels:

Based on the total points a product earns across these five categories, it receives one of four certification levels. These tiers create a clear, easy-to-understand hierarchy of environmental performance, allowing specifiers to choose a product that aligns with their specific project goals. The levels are:

: Use of recycled content and environmentally friendly raw materials. nsfs 347 work

For architects and green building professionals, navigating "greenwashing" can be incredibly difficult. Many products claim to be eco-friendly without data to back it up.

To achieve a high rating, such as the Platinum Certification held by industry leaders like Sika Sarnafil , products are assessed in the following areas:

: Specifying an NSF 347 certified membrane directly contributes to points in major green building rating systems, including LEED v4/v4.1 (under the pilot credits or material optimization categories) and the Green Globes system. : Tracks bio-based, recycled, or responsibly sourced raw

Follow this sequence every time you hear "347 work" called out on a jobsite.

: It replaces manufacturer self-declarations with rigorous, independent, third-party science.

Yes. Many private defense contractors (e.g., KBR, AECOM, Fluor) employ civilian crews certified for NSFS 347 work. However, the work must still be overseen by a government quality assurance representative (QAR). The levels are: : Use of recycled content

: Evaluation of energy efficiency, waste minimization, and greenhouse gas reductions during production.

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
