Calcium silicate - high-temperature insulation material for industry & refractory construction
Calcium silicate is a lightweight, pressure-resistant, high-temperature insulation material and is used as economical backing insulation in numerous industrial and refractory applications. Due to its excellent thermal and mechanical properties, calcium silicate is ideal for high-temperature applications up to approx. 1100 °C.
The material has proven itself in particular in industrial furnace and dryer construction, in plant and apparatus construction, in the cement industry, the petrochemical industry and in domestic fireplaces.
Properties & advantages of calcium silicate
Very good thermal insulation with low thermal conductivity
High thermal stability and good compressive strength
Low heat storage for energy-efficient processes
Low bulk density - light and easy to handle
Non-combustible and highly temperature-resistant
Easy to process (sawing, drilling, milling)
Large-format boards for economical processing
Durability & processing
- Calcium silicate is resistant to reducing protective gases, including
- Hydrogen (H₂)
- Carbon monoxide (CO)
- Methane (CH₄)
- Ammonia (NH₃)
- Nitrogen (N₂)
For applications in combination with refractory concretes, the use of a hydrophobic barrier primer is recommended to reduce the penetration of mixing water and avoid additional barrier layers.

Frequently asked questions (FAQ)
Does calcium silicate absorb moisture?
Does calcium silicate absorb moisture? Calcium silicate is capillary-active and can absorb moisture. When used in conjunction with fireproof concrete or damp materials, a hydrophobic barrier primer is recommended to reduce water penetration.
How can calcium silicate be processed?
Calcium silicate is easy to work with and can be sawn, drilled, or milled using standard tools. This enables quick and economical installation.
In what forms is calcium silicate available?
Calcium silicate is generally available in sheet form. In addition, molded parts (milled) can be supplied on request for specific projects.
Can calcium silicate be combined with other insulation materials?
Yes, calcium silicate is often used in combination with other high-performance insulation materials to achieve particularly low heat loss and compact designs.
