Thermafiber RainBarrier CI High Compressive (80) Mineral Wool Insulation

Select regional version:


The object content is configured for use in Canada, but it may also be suitable for use in other locations.


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.
