The NSF/ANSI 347 Sustainability Standard for Single Ply Membranes provides objective, neutral and transparent data to use to compare and assess the sustainable nature of different products. Based on life-cycle assessment principles, NSF/ANSI 347 employs an easy-to-use point system to evaluate roofing membrane products against established prerequisite requirements, performance criteria and quantifiable metrics in five key areas: product design, product manufacturing, membrane durability, corporate governance and innovation.

Criteria examples include environmental management systems, energy conservation, waste minimization, water conservation and greenhouse gas reductions. Certification is based on point totals to achieve Conformant, Silver, Gold or Platinum level. Platinum indicates the highest score and the highest certification earned.

“Sustainable roofing is an important component of sustainable construction,” said Whelan. “Sika Sarnafil products and initiatives have been a hallmark of sustainability in commercial and industrial buildings for over 45 years. NSF/ANSI 347 enables building owners, architects, and contractors to more easily compare products and manufacturers based on their sustainability, environmental impact and practices.”
