Cavitymate™ XPS Insulation

Cavitymate™ XPS Insulation is a STYROFOAM™ Brand XPS solution designed just for cavity walls, conveniently sized to fit between wall ties. All Cavitymate™ products resist moisture in all forms and help prevent moisture (condensation) from forming in cavity walls. Achieve even higher insulating power in cavity walls with Cavitymate™ Ultra, featuring 5.6 R-value per inch and designed to fit snug between brick wall ties. Cavitymate™ Ultra is used in the Ultra Air Barrier Wall System, a systematic way to integrate the air barrier and moisture barrier into one integrated wall system.

    1 Values are consistent with the criteria of ASTM C578 and the requirements of the FTC R-value rule (16 CFR Part 460). R means resistance to heat flow. The higher the R-value, the greater the insulating power. Ask your seller for the fact sheet on R-value.

    2 Vertical 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. For static loads, 3:1 is suggested. For dynamic loads, 10:1 is suggested.

    3 Based on 1” (25 mm) thickness.
