SILCA is the international service and sales company of the Calsitherm Group, specializing
in high-temperature materials and lightweight thermal insulation in various applications.
As the only German manufacturer of calcium silicate, we have demonstrated in the past
years that, through innovative products, both safety and productivity during the installation of
fireplaces may further be improved. This is guaranteed by means of close cooperation with
specialist tradesmen and retailers, as well as through the wealth of experience that SILCA
GmbH has been able to gain over the years, not least in insulation in the industrial sector.

SILCA® 250KM replaces both fire protecting wall and thermal insulation in only one construction material and not only for this reason guarantees more favorable results than comparable products. The required thickness of the insulation layer is determined on the basis of the assembly instructions of the stove manufacturers, the technical rules TR-OL and further national regulations. Depending on the individual case of application and where appropriate, an active air ventilation has to be provided.

The main components of the SILCA calcium silicate boards are lime and sand. These are physiologically safe and Classified as environmentally compliant construction material. This is guaranteed by our modern production facilities, permanent quality control, external supervision and certification according to DIN EN ISO 9001: 2008. The environmental compatibility is certified by the environmental product declaration according to ISO 14025 and EN 15804 issued by the Institut Bauen und Umwelt e.V. (German institute for construction and environment), declaration nro. EPD-CSP-2013111-D.
