Silca® 250KM
Over the past years CASITHERM / SILCA has been the only German producer of calcium silicates to show that with innovative products you can continuously improve both the safety and productivity in the assembly of fireplaces.
SILCA® 250KM insulation boards 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.
In Europe, the SILCA® 250KM is a well-established thermal insulation board used for the protection of mounting walls and for the cladding of fireplaces. This calcium silicate insulation board is authorized by the Deutsche Institut für Bautechnik Berlin (German Institute for Civil Engineering), national technical approval no. Z-43.1 4-117. 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 SILCA’S 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 no. EPD-CSP-2013111-IAC2-DE
