Thermafiber® RainBarrier® ci High Compressive (80)

Why choose mineral wool insulation?

Thermafiber® RainBarrier® ci High Compressive (80) continuous insulation boards are designed to support cladding attachment with minimal penetrations. The use of ThermaCrimp™ technology allows for excellent compressive strength while providing thermal efficiency, non-combustibility, water repellency, and flexibility when working with uneven substrates. RainBarrier® ci High Compressive (80) can be used behind light weight cladding — including combustible and open-joint assemblies.
