Thermafiber® RainBarrier® ci High Compressive Max insulation boards are designed to support cladding attachment with minimal penetrations. The use of ThermaCrimp™ technology allows for superior compressive strength while providing thermal efficiency, non-combustibility, water repellency, and flexibility when working with uneven substrates. RainBarrier® ci High Compressive Max can be used behind heavy weight cladding types – including combustible and open-joint assemblies.

Thermafiber® RainBarrier® ci High Compressive insulation uses ThermaCrimp™ technology to make the highest compressive strength mineral wool continuous insulation on the market. Designed to be used behind any cladding type - including combustible and open-joint assemblies.
