Roxul CavityRock® MD & DD
Continuous Insulation for Optimal Thermal Performance
Roxul CavityRock® is a non-combustible, water repellent insulation board specifically engineered for cavity wall and rainscreen applications. As a continuous insulation (ci), CavityRock provides excellent thermal performance and minimizes thermal bridging casued by stud assemblies.
Applications:
This product is specifically designed for use in cavity wall and rainscreen applications.
Two Product variations:
CavityRock MD (mono density) delivers an R-value/inch of 4.2 and is available in thicknesses of up to 2 inches.
CavityRock DD - For assemblies requiring higher R-values, Roxul's exclusive, dual density CavityRock DD delivers an R-value of 4.3/inch in thicknessess of 2.5 to 5 inches. This unique insulation combines a high density outer layer and a more compliant, low density inner layer that are created simultaneously in our proprietary manufacturing process.
Properties:
- Non-combustible stone wool insulation with melting point of approx. 1177°C (2150°F)
- Easily cut
- Fire resistant due to its high melting temperature
- Water and moisture resistant; does not absorb moisture to maintain insulating value
- Chemically inert
- Does not rot, promote mildew, fungi, or bacteria, or sustain vermin
- CFC- and HCFC- free product and process
- Made from Natural and Recycled materials
