Calcium silicate insulation board

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-20180010-IBC1-DE.

The boards are pressed on one of the world’s largest filter presses for the production of calcium silicates to a dimension of 3,000 x 1,250 mm. The standard dimensions are 1,250 x 1,000 mm, 1,250 x 500 mm and 1,000 x 625 mm. The standard thicknesses range from 30 mm to 100 mm. A further quality feature of the SILCA calcium silicate boards is the firm and dust-free moulding skin. Therefore, a further field of application is the lining of fireplaces.

Apart from the standard dimensions individual cuts can be produced directly in the plant on demand. SILCA® 250KM can be treated with standard wood machining tools and also be screwed on assembling.

Construction board for fireplaces

SILCAHEAT® 600C is an innovative board for the construction of fireplaces. It combines the natural desire for thermal radiation in the operation of domestic fireplaces with the modern requirements on a construction material for easy and fast assembling of fireplaces.

SILCAHEAT® 600C is a high temperature resistant hybrid material composed of calcium silicate and carbon. Due to the high proportion of graphite the construction board has excellent heat conducting properties for the lining of fireplaces.

SILCAHEAT® 600C is not an insulation board!

SILCAHEAT® 600C is certified by the Materialprüfungsamt NRW (Materials Testing Office of North Rhine Westphalia).

SILCAHEAT® 600C is a construction board for fireplaces of the newest generation. Being applicable up to 1000 °C it convinces with a light weight and at the sa me time high compressive strength and excellent edge stability. The radiant heat is given off to the room in a comfortable and homogeneous way. SILCAHEAT® 600C is thermal shock resistant, precisely treatable and despite its good thermal conductivity has only a very low thermal expansion. Of course the construction board for fireplaces is free of asbestos. Cuttings and residues can be disposed of as building waste.

The treatment of SILCAHEAT® 600C is easy, fast and safe. The solid self-supporting construction boards for fireplaces can be treated with standard wood machining tools and bonded with SILCACON adhesive. Countersunk screws can be used without pre-drilling, this multiplies the possibilities of assembling. According to the customers’ desires SILCAHEAT® 600C construction boards for fireplaces may be plastered or decorated with natural stone or stove tiles after mounting.

SILCACON lime plaster and SILCACON smoothing lime can be used for plastering of the SILCAHEAT® 600C construction board for fireplaces. Due to the high temperatures SILCACON first coat shall not be applied. However, a pre-treatment of the board with SILCADUR HTI impregnation is recommended.

The plaster is reinforced with heat-resistant SILCATEX-SE glass mesh fabric.
