The first product category rule (PCR) in North America for roof coating materials has been developed by the Roof Coatings Manufacturers Association (RCMA) and NSF International. Products covered in this PCR include fluid-applied and adhered coatings used for roof maintenance or roof repair, or as a component of a roof covering system or roof assembly.
A PCR defines how to conduct a life cycle assessment for a particular product group and what to include in the resulting report. This enables product environmental information to be more transparent and useful to the marketplace, says RCMA.
A life-cycle assessment measures inputs, outputs and environmental impacts of a product across its lifespan. The environmental product declaration (EPD) is the third-party-verified report that explains the data generated from a life cycle assessment. What is included in the EPD is also defined by the PCR, says RCMA.
The NSF International National Center for Sustainability Standards (NCSS) developed the PCR with participation from a panel of RCMA members, suppliers, regulatory agencies, environmental organizations and end users.
Verified environmental product declarations (EPDs) as defined by this PCR may help building projects qualify for points through the LEED v4 Material and Resource credits and comply with the International Green Construction Code (IgCC).
