DuPont™ Styrofoam™ Brand Panel Core 30 XPS Insulation
High-Performance Insulation for Composite Panel Applications U.S. HFC Regulation Compliant Formulation
DuPont™ Styrofoam™ Brand Panel Core 30 XPS Insulation
High-Performance Insulation for Composite Panel Applications U.S. HFC Regulation Compliant Formulation
<br><b>DuPont™ Styrofoam™ Brand Panel Core 30 Extruded Polystyrene (XPS) Insulation</b> is 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 30 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. The foam also resists absorption of adhesives, so less glue is required for effective, long-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.
3Based on 1” thickness.
