The ST-100 Series low GWP formulation represents a sustainable technology shift that reduces the product's embodied carbon, meets U.S. state HFC regulations 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.
The Styrofoam™ Brand ST-100 series, under the same product names you know, will be available for all the existing Styrofoam™ product lines: for example, Styrofoam™ Square Edge is available as Styrofoam™ Square Edge ST-100 XPS insulation. The change is easy to identify; we are modifying the color from the traditional blue to the new grey.
Above and beyond ensuring environmental compliance, we’re continuing to advance our 2030 Sustainability Goals and invest in global efforts and technology innovations to help you design and build energy-efficient, resilient and durable structures in this rapidly changing world.
Styrofoam™ Brand ST-100 Series XPS delivers the same R-value – R-5 per inch thickness – for long-term thermal performance. The grey color lets you know it was made more sustainably – with reduced embodied carbon - thanks to an innovative low global warming potential (GWP) formulation.
With the same thermal performance, moisture resistance, durability and ease of use, Styrofoam™ Brand ST-100 Series XPS Insulation – along with our complete building envelope solutions – delivers protection that’s a sure fit for all six sides.
