ROCKWOOL Comfortboard® 80 is a rigid stone wool insulation board designed for use as an exterior continuous insulation in residential and commercial construction.
Comfortboard 80 does not produce smoke or propagate flames, providing a critical line of defense that keeps occupants safe and reduces property damage in the event of a fire.
This stone wool product has been certified by the California State Fire Marshall's Building Materials Listing Program (BML). Vapor-permeable, Comfortboard 80 has the added benefit of allowing fast outward drying. The insulation also reduces thermal loss resulting in improved long-term thermal performance.
