Recently, the Spray Polyurethane Foam Alliance (SPFA) announced that it has completed the update of the ISO-compliant Life Cycle Assessment (LCA) and Environmental Product Declaration (EPD) documents every 5 years. LCA and EPD target three general spray polyurethane foam product formulations, including open-cell, closed-cell, and roofing foam. The SPFA update this year with Thinkstep (formerly PE International) also includes a category of products, low-pressure two-component closed-cell insulation and sealant foams. In addition, two (rather than one) separate environmental product declarations were issued, in line with the spray polyurethane foam industry trend to promote low global warming potential (GWP) blowing agents.

Rick Duncan, technical director of the Spray Polyurethane Foam Alliance, said: "In 2013, SPFA became the first industry association to develop and publish industry-standard ISO-compliant life cycle assessment and environmental product declaration documents for spray polyurethane foam. "The current update is critical to the industry as it keeps our LCA and EPD up-to-date and responds to the major shift that is taking place within our industry, namely the shift to more environmentally friendly blowing agents. It will greatly reduce the negative impact on the earth's environment and climate.”

SPFA initially launched the LCA project in 2013 to cooperate with thinkstep and its GaBI database, and the evaluation project includes three types of SPF products: open-cell low-density insulation Thermal foam, closed-cell medium density insulation foam and roofing foam. The updates currently being done by SPFA and thinkstep are in line with ISO requirements, which include the mandatory updating of LCA and EPD documents every 5 years. The update complies with the latest 2018 Insulation Product Category Rules (PCR), including the original product types, as well as some new additions, including a fourth product type, low-pressure two-component closed-cell insulation and sealant foam.

In addition, two separate EPD certifications were completed as the industry shifted to low GWP blowing agents. One of the EPD certifications covers HFC-based blowing agents for closed-cell foams, and the second EPD certification covers HFO-based (low GWP value) blowing agents. The addendum to each EPD certification conforms to the latest PCR requirements and will include a list of participating manufacturers and applicable products.

EPD certification leverages the results of the LCA to allow spray polyurethane foam contractors to help sustainable building designers earn points for using spray foam insulation and roof coverings in leading sustainable building projects. These projects include the US Green Building Council's LEED4 project, the International Green Building Code and GreenGlobes, among others.
