Beyond Blue

Low GWP Styrofoam™ Brand XPS

The low GWP formulation represents a sustainable technology shift that reduces the product's embodied carbon and supports DuPont's 2030 Sustainability Goals. This game-changing formulation is a new grey color instead of the traditional blue — so you’ll know it when you see it.

Published EPDs and Embodied Carbon

DuPont’s Styrofoam™ Brand Insulation GWP Phase-Down program offers lower embodied carbon product solutions compliant with specific Canada GWP Regulations without compromising on performance.
Remember: Embodied carbon should only be reported by manufacturers using third-party verified EPDs, and comparison of EPDs should be interpreted with caution due to complexity in modeling product life cycles and the lack of quantified uncertainty in reported values. Many factors, including embodied carbon and other sustainability considerations, should be used to guide product decisions.

*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
