Calcium Silicate Board - Board with low density and low thermal conductivity


This strong and lightweight board has a low thermal conductivity and can withstand very high temperatures and large temperature changes. The board absorbs and releases ambient moisture and therefore prevents formation of condensation that would cause mould and mildew growth.

Used for:

The board is used for temperature insulation, passive fire protection, and as a sturdy material in damp and wet areas. It is often used as a safe alternative to asbestos. Applications include walls in bathrooms and basements, fireplace enclosures, and insulation for industrial piping.


The calcium silicate is derived from naturally occurring limestone and micro silica derived from silicon production. 

The board can be sawn, drilled, screwed, and machined with traditional woodworking machines and tools.


Use it for insulation in a robust cooler for camping trips.

All samples come with a laminated information card, which includes contact details for the supplier.
