DuPont™ Styrofoam™ Brand Panel Core 20 Freezer XPS Insulation
High Performance Insulation for Walk-In Coolers and Freezers U.S. HFC Regulation Compliant Formulation
DuPont™ Styrofoam™ Brand Panel Core 20 Freezer XPS Insulation
High Performance Insulation for Walk-In Coolers and Freezers U.S. HFC Regulation Compliant Formulation
<br><b>DuPont™ Styrofoam™ Brand Panel Core 20 Freezer Extruded Polystyrene (XPS) Insulation</b> 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.
<p>
<b>Styrofoam™ Brand Panel Core 20 Freezer XPS Insulation</b> 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.

1R means resistance to heat flow. The higher the R-value, the greater the insulating power.
2Vertical compressive strength is measured at 10 percent deformation or at yield, whichever occurs first. Since Styrofoam™ Brand Extruded Polystyrene Foam Insulations are visco-elastic materials, adequate design safety factors should be used to prevent long-term creep and fatigue deformation.
