RainBarrier™ Insulation

Thermafiber® RainBarrier™ products are designed for exceptional performance in rain screen and cavity wall construction applications. RainBarrier™ 45 (standard density) & HD (high density) provide energy saving continuous insulation (ci), fire protection, and acoustical control while efficiently draining water from a wall cavity system. RainBarrier™ products are non-combustible and suitable for use with common z-girt, wall-tie and clip cladding attachment solutions with open or closed joint facades.

Choosing RainBarrier™ 45 or HD

If insulation is going to be left exposed for long durations prior to cladding installation, with extended exposure to the elements, consider installing higher density Thermafiber® RainBarrier™ HD continuous insulation.
