CALSITHERM: Quality and Innovation since 1977

We are the only German producer of calcium silicate thermal insulation materials!

CALSITHERM has been producing high quality calcium silicate materials in Germany since 1977, with weights ranging from 150 to 1,400 kilograms per cubic metre. Our products are used worldwide as insulation material in industries such as petrochemicals, cement plants, power plants, in metallurgy, in the ceramic industry and general furnace construction. We also offer fire protection solutions with our fire-retardant, mineral and non-flammable insulation materials.

Our light calcium silicates are perfectly suitable for energy-efficient building restoration. Our solutions for internal insulation, mould prevention, as well as renovation and fire protection boards are among the preferred products for building renovation. "An classic" old building or a "listed" historic or heritage building: our calcium silicate boards ensure ecological internal insulation. Structurally sound buildings is a subject very close to our heart. Which is why we always think of health safety of the users of the properties when developing our products.

CALSITHERM products, which consist of high-quality formulations, are used not only in machine and plant construction but also in non-ferrous metal foundries - coming in direct contact with the melt. We supply to companies specialising in low-pressure casting, pressure casting, billet casting and aluminium casting.

We are proud of our success, which stems from the high quality of our products, continuous development of innovative formulations and employee engagement. Eco-conscious thinking and the commitment to innovation and sustainability determine the work of our qualified team. Our customers thank us for this with their loyalty.

We operate globally, with our products and services available locally. That's how we are able to respond individually to the needs of our customers everywhere. Our focus is entirely on creating thermal insulations as ecologically and as economically as possible.
