DuPont™ Styrofoam™ Brand Panel Core 20 Freezer Extruded Polystyrene (XPS) Insulation was designed specifically for the walk-in cooler industry meeting specific regulations for this high performance market. It consists of a closed-cell, high performance core material featuring a proprietary extrusion process facilitating precise control of parameters like density, cell size and cell orientation. This process yields foam boards that can stand up to the most demanding and extensive array of composite panel applications.

Styrofoam™ Brand Panel Core 20 Freezer XPS Insulation is supplied in sheets that have been carefully engineered and planed to precise tolerances for an exceptional bonding surface. Its closed-cell structure resists absorption of water, which helps maintain panel integrity and insulating properties in low temperature applications and other environments with high humidity and moisture conditions. It also resists adhesive absorption, requiring less glue for effective and lasting adhesion of facer materials.
