NSF International (NSF) developed an American National Standard for Sustainable Roofing Membranes - NSF/ANSI 347 Sustainability Assessment for Single Ply Roofing Membranes.
Certification to NSF/ANSI 347 provides a transparent way for manufacturers of single ply roofing membranes to demonstrate their commitment to applying more sustainable approaches to product development and corporate operations, and enables them to differentiate their products in the marketplace.
Commonly used in the green building industry, single ply roofing membranes provide a waterproofing layer in both vegetative and conventional roof systems. The new NSF/ANSI 347 standard 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.
NSF/ANSI Sustainability assessment standards are recognized by companies, organizations and governments alike as credible tools for identifying and specifying more sustainable products. BD+C
