CAVITYROCK® is a semi-rigid insulation board designed for exterior cavity wall and rainscreen applications

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

Compatible with numerous cladding attachment systems, Cavityrock® is a durable solution with non-combustible characteristics meaning that the insulation will not develop toxic smoke or promote flame spread even when directly exposed to fire. Approved for use in many NFPA 285-compliant designs, it is an important component of fire-resilient exterior wall systems when used as a continuous insulation.

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

Comes in packs of 64 square feet.
