WASHINGTON — The Polyisocyanurate Insulation Manufacturers Association (PIMA) has announced the receipt of third-party-verified, ISO-compliant environmental product declarations (EPDs) for polyisocyanurate (polyiso) roof and wall insulations as manufactured by PIMA members across North America. An EPD is an internationally recognized and standardized tool that reports the environmental impacts of products.
These EPDs document that the energy-savings potential of polyiso roof and wall insulation over a typical 60-year building lifespan is equal to up to 47 times the initial energy required to produce, transport, install, maintain and eventually remove and dispose of the insulation. In addition to a high return on embodied energy, the EPDs document that polyiso roof and wall insulation offer high unit R-value per inch, zero ozone depletion potential, recycled content, opportunity for reuse and outstanding fire performance.
Beyond providing consistent and comparable environmental impact data, the PIMA polyiso EPDs also present information about additional environmental and energy characteristics, including the high net return on energy provided by polyiso roof and wall insulation.
Specifically, the polyiso EPDs describe the environmental impacts of the combined weighted average production for PIMA member manufacturing locations located across the United States and Canada, based on an established set of product category rules applicable to all types of building thermal insulation. The environmental impacts reported in the PIMA polyiso EPDs are derived from independently verified cradle-to-grave life cycle assessment (LCA) process, including all critical elements related to the resourcing, production, transport, installation, maintenance and eventual removal and replacement of polyiso roof and wall insulation.
Using the LCA process, the PIMA polyiso roof and wall insulation products are evaluated on a number of impact categories including global warming potential, ozone depletion potential, eutrophication potential, acidification potential and smog creation potential, as well as other environmental indicators including primary energy demand, resource depletion, waste to disposal, waste to energy and water use.
PIMA polyiso roof and wall insulation EPDs also meet the requirements of the U.S. Green Building Council (USGBC) LEED® v4 Green Building Rating System under Credit MRC-2 Building Product Disclosure and Optimization: Environmental Product Declarations as industry-wide or generic declarations that may be valued as one-half of an eligible product for the purposes of credit calculation.
“These third-party-verified EPDs for polyiso roof and wall insulation products produced by PIMA manufacturers reflect our industry’s commitment to sustainability and transparency in reporting environmental performance,” said Jared Blum, president of PIMA. “These EPDs will be a valuable tool to provide environmental information to all building and design professionals, and they should be especially helpful in meeting emerging criteria for green building design.”
