For panel integrity in tough conditions

Foam-board insulation engineered for the most demanding composite panel applications, Panel Core XPS Insulation is a STYROFOAM™ solution that provides a strong bond surface, resistance to moisture, and resistance to adhesives – which means you can save on glue.

 
 
 
 
 
 

Panel Core XPS Insulation

Panel Core Extruded Polystyrene (XPS) Foam Insulation is a STYROFOAM™ Brand closed-cell high performance core material used extensively in composite panel applications. Dow’s proprietary extrusion process enables precise control of parameters such as density, cell size and cell orientation. This yields foam boards that can stand up to the most demanding composite panel applications. Panel Core is supplied in sheets that have been carefully engineered and planed to precise tolerances for an exceptional bonding surface. The closed-cell structure of STYROFOAM™ solutions 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.

    1 Vertical compressive strength measured at 10 percent deformation or at yield, whichever occurs first.

    2 R means resistance to heat flow. The higher the R-value, the greater the insulating power.

    3 This numerical flame spread rating is not intended to reflect hazards presented by this or any other material under actual( fire conditions.

    4 Actual water vapor permeance for 1” thick material. Value decreases as thickness increases

    ** Per DOE-10 CFR Appendix B to Subpart R of Part 431. For foam produced as board stock “final chemical form” means after extrusion and ready for assembly into a panel or after assembly into a panel
