$3.62 / SQUARE FT
CAVITYROCK® DD is a non-combustible, lightweight and water repellent, rigid insulation board with a rigid upper surface for durability and enhanced strength, intended for use in cavity wall applications. Specifically engineered for this application, CAVITYROCK DD’s low moisture sorption enables it to maintain R-value and its mineral fibre structure allows for effective drainage of water which penetrates the exterior wall. In addition, because CAVITYROCK DD is a non-combustible insulation, installation of a fire stop is not required. The product is compatible with most air/vapour barrier systems, adhesives and wall ties.
