Thermafiber® RainBarrier® ci High Compressive Plus (110)

Why choose mineral wool insulation?

Thermafiber® RainBarrier® ci High Compressive Plus (110) continuous 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 Plus (110) can be used behind medium-weight cladding types — including combustible and open-joint assemblies.
