Modern buildings are designed, not to prevent moisture from entering, but rather to accommodate moisture once it has entered the cavity wall. Given the fact that a building's cavity wall is designed to accommodate moisture, and that moisture contributes to the loss of thermal resistance (Rvalue), of the cavity wall insulation, IT IS CRITICAL that R-value retention in a moist environment be the most important factor to consider when choosing cavity wall insulation. STYROFOAM™ CAVITYMATE™ and STYROFOAM CAVITYMATE Ultra extruded polystyrene insulation products have a unique closed-cell structure which leaves no voids between the cells. They are unsurpassed in resisting water penetration and offer high compressive strength and durability.
There is a STYROFOAM insulation product that is right for every exterior cavity wall block backed application.
