ROCKWOOL 2 in. Comfortboard® 80 Thermal Insulated Sheathing, R-8, 2 ft. x 4 ft. Sheets
ROCKWOOL Comfortboard® 80 is a rigid stone wool insulation board designed for use as 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.
