Powerwool
Outside Insulation
Strengthen your building envelope with PowerWool™ Rigiboard™ 80, a rigid mineral wool insulation board engineered for durability, fire safety, and long-term thermal performance. Designed for exterior continuous insulation on residential wall assemblies, Rigiboard™ 80 delivers reliable performance under demanding cladding loads while supporting moisture management, energy efficiency, and occupant comfort. At 8 lbs/ft³ with 616 psf of compression resistance, its rigidity and compressive strength make it well-suited for mechanically fastened cladding systems and layered wall assemblies. PowerWool™ Rigiboard™ 80 helps create safer, quieter, and more resilient homes by resisting fire, repelling moisture, and maintaining stable R-4.2-per-inch thermal performance over time. It’s approved for use in Canada and the U.S., and suitable for substitution in rated NFPA 285 and ASTM E119 wall assemblies.
