Introducing DuPont™ Styrofoam™ ST-100 Series XPS Insulation
The Styrofoam™ Brand ST-100 Series has been formulated to meet sustainability goals for climate action regulations in U.S. states. But some things remain unchanged: these new XPS products offer the same high performance and long-term value under the same Styrofoam™ product names with ST-100 descriptor – so there’s no need to change your specifications.
For additional details on compliance, refer to our U.S. compliance map and ICC-ESR 4755 code report.
For a complete list of current Styrofoam™ Brand ST-100 product lines with IRC and IBC building code application approvals, refer to ICC-ESR 4755.

Note+: DuPont can offer customers the maximum two product valuation towards the Option 2, 1-point Embodied Carbon/.LCA Optimization credit.
DuPont™ Styrofoam™ Brand XPS also qualifies as 1 product towards the Option 1, 1-point.
*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

GWP Reduction
Our history is rooted in innovation and Styrofoam™ Brand XPS is the industry leader – allowing us to deliver better, more-sustainable technology for modern building needs. The low GWP Styrofoam™ Brand XPS is another example of our long-term commitment to global sustainability and environmentally compliant building solutions.
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.
New color.
Same value.
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.
Styrofoam™ Brand ST-100 Series products are compliant in HFC regulated U.S. states. Refer to the Styrofoam™ Brand XPS Code Report ICC-ESR 4755 for details.
