RainBarrier® 45 insulation
Add to project

Product Description

Thermafiber® RainBarrier® Continuous Insulation products are designed for exceptional performance in rain screen and cavity wall construction applications. Thermafiber® RainBarrier® 45 insulation provides thermal insulation, fire resistive characteristics, and acoustical control while efficiently draining water from a wall cavity system. Its natural, dark color provides camouflaging in open joint facades and eliminates 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. All Thermafiber® RainBarrier® products are non-combustible and compatible with common wall ties, adhesives, and air barrier systems.
