- Dimensional stability to maintain performance
- Inorganic, does not promote mold growth
Why use stone wool insulation
- Noncombustible and fire resistant, stone wool works to contain a fire and prevent its spread.
- Vapor permeable enabling wall systems to have superior drying potential, minimizing the risk of condensation and water accumulation.
- Stable long-term R-values for superior thermal performance.
- Superior compressive resistance and compatible with screw-through mechanically-supported cladding systems.
- Reduces thermal bridging through wood framing, leading to a higher-performing building envelope.
- Stone wool provides excellent noise reduction and sound absorption to help you create quieter, more productive environments.
Applications
- Installed in above-grade walls as continuous exterior insulation (ci).
- Below-grade exterior-insulated foundation walls and basements.
- Under flat concrete slabs.
- One-coat and three-coat insulated stucco cladding.
- Wood-framed cathedral ceilings.
