The following PIMA members participated in the development of one or more of the industry-average EPDs for polyiso products. We invite you learn about them and specify their products with transparency documentation.

In the United States: Polyiso insulation products conform to the ASTM C1289 product standard.

In Canada: Polyiso insulation products conform to the CAN/ULC-S704 product standard.

Environment: Polyiso insulation manufacturers are widely recognized for their leadership in the use of low-GWP blowing agent technologies and adoption of long-term thermal resistance (LTTR) testing to measure and report the thermal performance of products.

To provide EPD users with full transparency of environmental impacts, the industry-average EPD for roof insulation includes a full replacement of a building’s roof system, including the polyiso roof insulation, during the 75-year service life. The LCA was modeled this way because a full roof system replacement is common for all buildings at least one time over the course of 75 years. As such, the reported environmental impacts will appear greater than what is reported in product EPDs that do not include a replacement during the building service life. EPD users should check the scope (what is included and what is not) when reviewing any EPD for roof insulation products.

More information on the industry-average EPDs (also available in French) is available on the PIMA website.

A portion of the catalog proceeds goes to the National Park Foundation
