ROCKWOOL Smartrock® combines stone wool with an integrated smart vapor retarder to create a continuous insulation solution on the interior side of exterior concrete and masonry wall assemblies.
Smartrock is noncombustible, and achieves a Class A fire rating for flame spread and smoke development. The integrated membrane controls vapor movement, and creates an airtight layer when properly sealed, enhancing the overall efficiency of the wall assembly.
This high-performance solution is backed by ICC-ES ESR-5374, making it a reliable choice for both new construction and retrofit projects. Smartrock supports the preservation of original facades, compliance with thermal code requirements, and adherence to lot line restrictions.
Understanding smart vapor technology
The integrated smart vapor retarder – utilizing INTELLO® PLUS by Pro Clima – provides smart vapor control, or vapor variability. This allows the assembly to adapt to changing seasons and varying humidity conditions, minimizing the risk of damage and reducing the potential for entrapment of moisture within the building enclosure.
