Roxul has launched two new CavityRock products, both of which serve as continuous insulation in both cavity and rainscreen applications. CavityRock DD is manufactured using a proprietary dual-density technology and is offered in thicknesses of 2-1/2" or more. CavityRock MD is a mono-density product that is available in 1", 1-1/2", and 2" thicknesses. Roxul CavityRock is made from a combination of natural stone and recycled material, is fire resistant and water repellent, and has a low moisture absorption rate for repelling and draining water that penetrates the exterior wall.
