Comfortboard® 80 Rigid Stone Wool Insulation Board 1-1/2 in. x 24 in. x 48 in. (48 sq. ft. Per Bag) | SAFB1.5-CFB80-24-RW

Rockwool's Comfortboard® 80 offers superior fire resistance, with a melting point of approximately 2150°F (1177°C), and 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. Its vapor-permeable nature allows for fast outward drying, minimizing the risk of condensation and water accumulation within wall assemblies. The board's durability and resistance to moisture, rot, and mildew contribute to its long-term performance and reliability in various building applications.
