Styrofoam™ Brand Panelmate™

Commercial | Residential | Multifamily | Wall

Insulation that fortifies precast concrete panels

Made to pack more thermal performance into insulated precast concrete panels. Panelmate™ XPS Insulation is a long-lasting Styrofoam™ solution for sandwich panel applications, maintaining thermal values in the high moisture content of the concrete panel manufacturing process.


Styrofoam™ Brand Panelmate™

The R-value (RSI) of Styrofoam™ Brand Panelmate™ extruded polystyrene (XPS) insulation products helps create concrete wall systems that are durable, strong and energy efficient. These products are highly resistant to moisture due to DuPont’s distinct extrusion process. Closed-cell, rigid plastic foam is extruded with smooth, high-density skins making Panelmate™ and Panelmate™ Ultra moisture resistant and helping to maintain their thermal value when subjected to the concrete panel manufacturing process.
