CANTON, Mass. - March 1, 2016 - Sika, the worldwide market leader in thermoplastic roofing and waterproofing membranes, has published product-specific environmental product declarations (EPD) for its Sarnafil S327 and G410 single-ply PVC roofing membranes, as well as its Sikaplan Adhered and Fastened single-ply PVC roofing membranes.
The EPDs, which are verified by ASTM International, provide a summary of detailed environmental impact data developed in a life cycle analysis of the products. This information allows architects, contractors and building owners to make better informed decisions when it comes to product purchases. ASTM International is a globally recognized leader in the development and delivery of voluntary consensus standards.
“EPDs are an important tool to help designers and building owners understand the life cycle impacts of the products they select,” said Jay Thomas, Vice President of Marketing for Sika Roofing. “Demand for them is increasing as the design community becomes more familiar with the environmental impact information that they provide.”
Interest in creating EPDs has grown dramatically since the most recent versions of Green Globes and the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) program now award credits for buildings incorporating the use of published declarations.
EPD specifications are established by a product category rule (PCR), which is created by a committee of interested stakeholders and defines how to conduct a life cycle assessment (LCA) for a product group. Each of the Sika roofing membrane declarations follow Section 11 of ASTM International’s Product Category Rules for Preparing an Environmental Product Declaration for Single-Ply Roofing Membranes from November of 2013.
The declared roofing membranes are designed for low slope and steep slope roofing applications. The Sarnafil S327 and Sikaplan Fastened membranes include an internal polyester scrim reinforcement to provide the tear resistance required for mechanically-fastened roof systems, while the Sarnafil G410 and Sikaplan Adhered membranes are reinforced with a fiberglass mat in order to provide the dimensional stability required for adhered roof systems.
