VARMSEN® calcium silicate board is used to construct fireplaces and provide insulation. It creates a light and rigid structure, and is easy to process using conventional carpentry tools. The board is mounted using ISOL GLU E+ glue and TD bolts. The board is a perfect insulator of high temperatures present inside a fireplace mantel, ensuring a safe temperature level on the outer side. It replaces a traditional solution based on gypsum cardboard and mineral wool. It is perfect for insulating wooden beams, side walls and walls behind fireplaces.
VARMSEN® fireplace board is a calcium gypsum insulating board of perfect insulating value, designed for applications in maximum temperatures of up to 1000 °C. VARMSEN® fireplace board is also a safe-supporting structural board of high strength parameters, designed for e.g. preparation of structural elements of a heating fireplace mantel. VARMSEN® fireplace board is also a safe and environment-friendly product as it is stringless. Due to the processes of surface hardening and autoclaving in the production phase, VARMSEN® fireplace board is dust-free.
VARMSEN® calcium silicate board, due to its properties, provides perfect insulation for any devices associated with combustion or high temperatures, such as: furnaces, ovens, boilers, pit furnaces, network regenerators etc. Due to high resistance to carbon monoxide and hydrocarbons, VARMSEN® calcium silicate board may be used in furnaces with reducing atmosphere. No decomposition of carbon deposit was found after exposure to CO in the temperature of 450°C for 200 hours. VARMSEN® boards may also be used as a support insulation for any fireproof structures – dense chamotte bricks, insulating fire-resistant bricks, cast products, fireproof plastics etc.

Ready to use. Intended as a primer that improves adherence to VARMSEN® fireplace board and for further layers of the system. May also be applied to typical construction substrates only if direct contact between the preparation and mineral components of the substrate is possible. The primer does not contain solvents and reinforces VARMSEN® fireplace board and further layers of the system, as well as equalises their absorbency. It features high water vapour permeability. It restricts the production of efflorescence.
