Sika Roofing Receives Recertification to NSF Sustainability Platinum Rating

Sarnafil G 410 and S 327 membranes have once again achieved Platinum certification to the NSF/ANSI 347 Sustainability Assessment for Single Ply Roofing Membranes.
Sika Roofing leads its industry in adopting more sustainable practices that help its customers and organizations meet the continued growth in green buildings.

Sika, the worldwide market leader in thermoplastic roofing and waterproofing membranes, is proud to announce the achievement of Platinum recertification to the NSF/ANSI 347 Sustainability Assessment for Single Ply Roofing Membranes for its Sarnafil S 327 and G 410 roofing membranes, including its new Sarnafil Textured Membrane.

Sika was the first roofing manufacturer to earn this highest possible certification to NSF/ANSI 347, which is the leading consensus standard for evaluating and certifying sustainable attributes of single ply roofing membranes over their entire product life cycle.

“As the importance of sustainable roofing continues to move to the forefront of the single ply industry, our commitment to these practices cannot be understated,” said Brian J. Whelan, Executive Vice President of Sika Roofing. “We are incredibly proud to continue to lead the way with the Platinum recertification of our Sarnafil S 327 and G 410 membranes, which were the industry’s first to achieve Platinum certification back in 2013.”

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:

1.    Product design
2.    Product manufacturing
3.    Membrane durability
4.    Corporate governance
5.    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, the most difficult to achieve, indicates the highest score and the highest certification earned.

“Sika Roofing leads its industry in adopting more sustainable practices that help its customers and organizations meet the continued growth in green buildings,” said Jenny Oorbeck, General Manager of Sustainability at NSF International.

Sika is the only roofing manufacturer to recycle old roofing membrane into new roofing membrane and whose recycled content claims have been UL certified.
