Calcium silicate insulation for high-temperature applications
Machinable, outstanding performance and structurally strong insulation
You can rely on Promat’s calcium silicate materials for high-temperature insulation to save energy and space, reduce CO2 emissions, increase the capacity of your application and enhance safety. Even in the most demanding environments, our calcium silicate boards, pipe sections, powders and custom-made parts maintain their thermal performance level and structural integrity. They can be combined with other materials from our range for an engineered solution. Our highly skilled experts are ready to design and develop the most efficient thermal insulation solution for your requirements.
Calcium silicate insulation - thermal and mechanical performance

Calcium silicate insulation - thermal and mechanical performance
Promat’s calcium silicate materials for high temperature insulation cover the complete range of low, medium and high density and compound insulation boards. They offer a very low thermal conductivity and excellent structural support, and are resistant to moisture and chemicals. Due to their minimal thermal shrinkage they have an extended service life without loss of performance.
The excellent structural integrity of our calcium silicates makes them easily machinable and even enables the machining of complex structures. Moreover, they are easy and safe to handle, install and maintain, and can be used for new constructions as well as retrofits.
