ROCKWOOL Comfortbatt® Stone Wool Thermal Batt Insulation, R-Value: R-38, Batt Insulation, 23 in Width, 47 in Length, 9-1/2 in Thickness, 22.5 sq-ft Coverage Area, Use Location: Exterior Wood and Steel Stud

ROCKWOOL Comfortbatt is a semi-rigid stone wool batt insulation for exterior wood and steel stud applications in both new construction and renovations. It features a unique flexible edge designed to compress as the batt is inserted into walls, attics, ceilings and floor frames, then spring back, expanding the batt against the frame studs to give a complete fill. This flexibility ensures the expected R-value is achieved and maintained. Non-combustible and fire resistant, Comfortbatt will not develop toxic smoke or promote flame spread, even when exposed directly to a fire. It also offers water and moisture resistance and excellent sound absorbency. Comfortbatt is an effective way to improve a home's energy efficiency. It is GREENGUARD Gold Certified and contributes to a healthier indoor environment.
