Styrofoam XPS insulation introduces reduced GWP formulation

Reduced Global Warming Potential (GWP) product contributes to DuPont's sustainability goals.

DuPont™ (NYSE: DD) launched its reduced global warming potential (GWP) solution for Styrofoam™ Brand Extruded Polystyrene (XPS) Foam Insulation on January 1, 2021.

As Canada continues the phase-down of hydrofluorocarbon (HFC) blowing agents, DuPont is ready with a reduced GWP formulation — in a new, design friendly grey color — that maintains the same industry-leading performance of the familiar blue insulation material.

The quality and properties of the new Styrofoam™ brand grey insulation products meet the strict Underwriters Laboratory of Canada (ULC) classification listings, and the assemblies evaluated achieve the same reliable ULC and Factory Mutual (FM) approvals. Additional third party, industry certifications publishing soon include an Environmental Product Declaration (EPD), which is a third-party verification report of Styrofoam™ brand insulation’s environmental impact across its entire life cycle.

“We know that sustainability is more than just how our products are produced. Sustainability is also about how they perform,” says Jeff Hansbro, Global Advocacy Director at DuPont. “That is why we relied on our decades of scientific expertise and innovation in this rigid foam insulation product category. We did not want to risk the quality, consistency and energy efficiency that customers have relied on for nearly 80 years.”

“As the leader in the industry, we worked very closely with regulatory bodies to help shape the wisest path to achieve a perfect balance of performance, reliability and sustainability,” he says. “Our new formulation delivers the same high quality, thermal performance, moisture resistance, durability and ease-of-use. It has been evaluated by third-party certifications to meet or exceed standards for both sustainability and performance. Right now, we are ready with this great solution for the building and construction industry.”

As part of a multi-phased approach, the grey, reduced GWP product line will deliver greenhouse gas (GHG) reductions in support of the Paris Climate Agreement and along a more aggressive timeline than the Kigali Amendment to the Montreal Protocol.

This new Styrofoam Brand XPS Insulation aligns with and enables progress toward DuPont’s 2030 Sustainability Goals, which include a commitment to reduce GHG emissions by 30 percent on a path to carbon neutrality by 2050. DuPont Performance Building Solutions has committed to reducing GHG emissions by 75 percent to support the corporate goals.
