High density calcium silicate board

PROMATECT®-H cement bonded, calcium silicate-based boards are used for both high temperature insulation and passive fire protection. These large-size boards can withstand peak temperatures of 400 °C and offer superior mechanical properties for self-supporting constructions.

PROMATECT®-H boards are hygroscopic and vapour permeable. Moisture content is therefore automatically regulated by the application environment.
