Designed for masonry cavity wall applications, unlike some rigid foam insulation, FOAMULAR® extruded polystyrene insulation is virtually impervious to moisture. This moisture-resistant property – along with its high R-value, light weight, competitive price and wide range of sizes – makes it ideal for use in a cavity wall system. FOAMULAR® CW25 is comparable to Dow CAVITYMATE™ Plus Insulation Series.
