ROCKWOOL CAVITYROCK®

ROCKWOOL Cavityrock® is a semi-rigid stone wool insulation board that is available in mono and dual density, 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.

Also available in a black matte finish for open-joint cladding systems, Cavityrock® Black combines your insulation install with masking in a single step, reducing installation time and material cost to achieve your desired design aesthetic.
