Continuous Insulation

STANDOUT PERFORMANCE DESIGNED TO BLEND IN

Owens Corning® Thermafiber® RainBarrier® Dark™* continuous insulation semi-rigid products are produced with a bonded black facing that is designed for exceptional performance in rainscreen and cavity wall construction applications. Thermafiber® RainBarrier® Dark™ is the same continuous insulation you have come to know and trust from Owens Corning® Thermafiber® but offers camouflaging behind open-joint facade systems and eliminates the material and installation costs associated with an additional masking layer. Thermafiber® RainBarrier® Dark™ insulation provides thermal control, fire-resistive characteristics, acoustical control, and the ability to drain water from a wall cavity. All Thermafiber® RainBarrier® products are non-combustible, vapour permeable, and are easy to fabricate and install.

*Latest RainBarrier® products combine the benefits of RainBarrier® 45 and RainBarrier® HD as of April 2024.
