NSF standard provides manufacturers, specifiers and the building industry with verifiable, objective criteria to evaluate sustainable roofing products

ANN ARBOR, Mich. NSF Sustainability, a division of NSF International that provides sustainability standards development, testing, certification and claims validation for commercial, consumer and green products, has certified Sika Sarnafil S327 and G410 roofing membranes to the NSF American National Standard for sustainable roofing membranes, NSF/ANSI 347.

Certification to NSF/ANSI 347: Sustainability Assessment for Single Ply Roofing Membranes is based on point totals to achieve a conformant, silver, gold or platinum level certification. Sika Sarnafil is the first company to earn the highest achievement, the Platinum level certification to the standard, providing architects and contractors with a certified sustainable option for roofing membranes.

NSF/ANSI 347 provides a framework for assessing the environmental and societal impacts of single ply roofing membranes across the product life cycle — from raw material extraction through manufacturing, use and end-of-life management. By earning Platinum level certification for its products, Sika Sarnafil demonstrates its commitment to apply sustainable approaches to product development and corporate operations. Certification also differentiates its products in the marketplace, enabling a preferred vendor status with those that seek sustainable products.

NSF/ANSI sustainability assessment standards are recognized by companies, organizations and governments as credible tools to identify and source sustainable products. For example, the U.S. Government Services Administration (GSA), through Executive Order 13514. has set a goal to ensure 95 percent of all new contracts require products and services with more sustainable attributes (e.g. energy and water efficient, recycled), many of which are identified as criteria in NSF/ANSI 347.

As the first to earn Platinum level NSF/ANSI 347 certification, Sika Sarnafil is providing a more sustainable product for builders and architects striving to achieve green building certifications or other sustainability goals and is setting a high bar for the green building industry, said Tom Bruursema, General Manager of the NSF International Sustainability Division.

Certification of our roofing membranes to NSF/ANSI 347 is further verification of our commitment to sustainable business practices, said Stan Graveline, Vice President of Technical Services, Sika Sarnafil. Sika Sarnafil is committed to helping building owners achieve their sustainability goals by providing sustainable, long lasting, energy efficient roofing products and by offering an industry leading roof recycling program that takes back old vinyl membrane and recycles it into new roofing membrane products.

To earn certification, Sika Sarnafils single ply roofing membranes and manufacturing process had to meet multi-attribute criteria outlined in NSF/ANSI 347. The standard employs a point system to evaluate roofing membrane products against established requirements, performance criteria and quantifiable metrics in five key areas:

  • Product Design Integration of environmental and life cycle thinking into the product design process
  • Product Manufacturing Quantification of the environmental impacts from manufacturing, and actions to reduce or eliminate those impacts
  • Membrane Durability Membrane physical properties, service life and repairability
  • Corporate Governance Human rights, child labor, forced labor, employee safety and education, and community responsibility
  • Innovation — Advancements beyond the requirements for product design, product manufacturing and long-term value

Sika Sanafils S327 and G410 single ply roofing membranes can now bear the NSF Sustainability Certified mark on products and in advertising. Certified products are publicly listed on NSFs website.

How the NSF/ANSI 347 Standard Was Developed

NSF International, which has developed more than 80 American national public health and sustainability standards, developed the standard in partnership with a diverse group of stakeholders through the NSF National Center for Sustainability Standards (NCSS). The NCSS used the American National Standards Institute (ANSI)-accredited consensus process to develop NSF/ANSI 347, which included input from manufacturers, suppliers, regulatory officials, academics, industry representatives and end users.

Membrane products covered by NSF/ANSI 347 include, but are not limited to, membranes produced from EPDM (ethylene propylene diene terpolymer), KEE (ketone ethylene ester), PVC (polyvinyl chloride), TPO (thermoplastic polyolefin) and PIB (polyisobutylene) polymers.
