Our reduced GWP formulations feature a new grey color and the same great performance.
As states and provinces across North America continue the phase-down of HFC blowing agents in response to current environmental codes and regulations, DuPont is phasing in new, reduced global warming potential (GWP) formulations of Styrofoam™ Brand Extruded Polystyrene (XPS) Foam Insulation. Styrofoam™ Brand XPS products manufactured with the new formulations will be produced in a new, design friendly grey. The changeover is taking place first in Canada and select states, with plans to expand the product offering going forward.
While DuPont™ Styrofoam™ Brand XPS products are being reformulated with next-generation sustainable technology for an improved reduced embodied carbon profile, the performance characteristics and consistent quality of the original extruded polystyrene foam insulation will not change. Because of our industry leadership, we worked with regulatory bodies to best define the path to balancing performance and reliability with greater sustainability. We tested and refined all our products to be sure that Styrofoam™ Brand XPS will continue to meet or exceed codes and regulations and deliver the performance you've come to expect – in a color that meets modern design aesthetics.
As of January 1, 2021, blue Styrofoam™ Brand XPS is transitioning to grey in Canada and select U.S. States. Throughout the transition period, both grey and blue colors will be available and compliant with current regulations where sold.

*To convert kgCO2e/m2RSI to kgCO2e/bdft, divide by 12.24. The 12.24 factor was calculated by the following equations:
1m2RSI = 1m2 * 1.14 inch = 1.02 ft3 (where 1m2 = 10.76 ft2 and 1.14 in = 0.095 ft)
1bdft = 1ft2*in = 1ft2*(1/12 ft) = 0.0833 ft3
1.02/0.0833 = 12.24 m2RSI / bdft

A unique closed-cell structure gives Styrofoam™ Brand XPS its exceptional moisture resistance and enables it to retain a high, long-term R-value of R-5 per inch – even after exposure to standing water, wet soil and other damp conditions. Additional performance attributes of Styrofoam™ Brand XPS include:
DuPont™ Styrofoam™ Brand XPS products are backed by the expertise of building science leaders dedicated to your success and warranties from a name you trust, including limited thermal warranties from 15 to 50 years including the Wall² system warranties and other system warranties.
DuPont™ Styrofoam™ Brand XPS Insulation has played a key role in the building and construction industry for nearly 80 years, enhancing energy efficiency and the sustainability profile of the entire building envelope. Thanks to the energy it saves over its lifetime, Styrofoam™ Brand XPS has been shown to help save more than 30 times the energy embodied in it. Based on published environmental product declarations, current Styrofoam™ Brand XPS will prevent at least 28 times more greenhouse gas emissions relative to its own carbon footprint over a 50-year period. Already manufactured with 100% renewable energy and a zero-ozone depletion formula, the sustainability benefits of Styrofoam™ Brand XPS include:
Third party verified Environmental Product Declarations (EPD) through ULSpot® are available for Styrofoam™ Brand products:
Grey, reduced GWP Styrofoam™ Brand XPS Insulation addresses the modern need for a dark reveal behind open-joint rainscreen systems or other applications where exposed insulation is desired. But that's not all. As a highly efficient continuous insulation, Styrofoam™ Brand XPS helps prevent thermal bridging which may lead to unsightly dark stains visible through cladding.
DuPont Performance Building Solutions is committed to being in step with where the construction industry is going. Our robust portfolio of proven and compatible products brings together decades of technology, expertise and innovation to provide water, air and thermal protection for all six sides of your building envelope.
1 R means resistance to heat flow. The higher the R-value, the greater the insulating power.
2 Styrofoam™ Brand Cavitymate™ Ultra Insulation, with patented carbon black technology, will continue to be produced in dark grey, delivering long-term insulating performance of R-5.6 per inch in wet cavity wall environments.
3 Not to be used in U.S. states with HFC regulations.
