Rockwool Cavityrock®

ROCKWOOL Cavityrock® semi-rigid stone wool insulation board available in mono and dual-density is designed for exterior cavity wall and rain screen applications.

Cavityrock® also offers energy efficiency with reliable thermal performance, improved acoustic comfort, and is moisture-resistant to maintain insulating value for the long-term.

Rockwool Cavityrock®, in thicknesses of up to 2 inches, is mono-density and in thicknesses of 2.5 to 6 inches is dual-density. The unique dual-density insulation combines a high-density outer layer and a more compliant, low-density inner layer that is created simultaneously in their proprietary manufacturing process.
