Calcium silicate board is a rigid, non-asbestos thermal insulation material based on xonotlite (6CaO·6SiO2·H2O). It combines low thermal conductivity, high mechanical strength and excellent fire resistance.
Composition
The board is manufactured from siliceous and calcareous raw materials with reinforcing fibres, then autoclaved into a stable crystalline structure.
