2 in x 2 ft x 4 ft Owens Corning Thermafiber RainBarrier HD Mineral Wool Insulation


Thermafiber® RainBarrier® HD is a high density board with a consistent 6.0 pcf density throughout the entire thickness of the product. The consistent density from top to bottom helps eliminate the need to orient the piece in a certain direction. Its natural, dark color provides camouflaging in open joint facades and helps eliminate the need for black facing. Thermafiber, Inc. does not recommend applying a black facing in open joint applications because the manufacturers of the facing do not support their long term exposure. Thermafiber® RainBarrier® HD continuous insulation products are designed for exceptional performance in rain screen and cavity wall construction applications. Mineral wool insulation provides thermal insulation, fire resistive characteristics, and acoustical control while efficiently draining water from a cavity system. All Thermafiber® RainBarrier® products are non-combustible and compatible with common wall ties and air barrier systems.
