DuPont™ Styrofoam™ Brand Panelmate™ Ultra Extruded Polystyrene Insulation provides all the benefits of Styrofoam™ Brand Panelmate™ XPS Insulation, but with an even higher R-value performance to meet your unique design needs.
Styrofoam™ Brand Panelmate™ Ultra
DuPont™ Styrofoam™ Brand Panelmate™ Ultra Extruded Polystyrene Foam Insulation contains patented carbon black materials in the foam for greater thermal performance over other extruded polystyrene insulations. This enhanced formulation helps the foam absorb infrared radiation, slowing its transmission through the foam and lowering heat flow. The Styrofoam™ Brand XPS product line gives you the proven thermal and moisture performance of the original XPS, plus the product options you need to design and build energy-efficient, resilient structures all the way to the top. It’s lightweight and easy to install, which makes the work go faster, and available through our wide distributor network. When and where you need it, Styrofoam™ Brand is there.
