vermiculite fireproof board

Vermiculite Boards

Vermiculite board is a refractory material made from exfoliated vermiculite and special inorganic binder that provides a high degree of heat resistance to temperatures up to 1100 degrees C and heat shocks. The use of vermiculite plates is aimed at improving the thermal insulation for both personal and industrial purposes. The main advantage of vermiculite is the preservation of temperature and fire resistance. The vermiculite plate has a low thermal conductivity and its specific density is up to 300 kg/cub meter.

Vermiculite fire boards are widely used in pellet stoves, fireplace, partition panel, fireproofing doors, wall claddings, ceiling, furniture, platforms for marine and vessels, etc. Vermiculite board also provides insulation and is used in soundproofing.

New Type of Insulation Material

Vermiculite Board is a new type of inorganic material, with expanded vermiculite as the main raw material, mixed with a certain proportion of inorganic adhesives, through a series of processing and become with high-temperature resistance, fire prevention, green environmental protection, insulation, sound insulation, no harmful substances in the plate. When heated to 1200℃ at a high temperature, no harmful gases will be produced, and the combustion performance reaches level I.

Vermiculite Fireproof Insulation Boards

With the feature of heat insulation and fire prevention, Vermiculite Fireproof Board / Brick is widely used as the thermal insulation and refractory material. And the fireboard can be worked easily with woodworking tools. It can be sawn, drilled, and sanded.

Vermiculite Fire-proof Insulation Board is often used as a heat shield, firebrick, register plates, or replacement fire bricks for wood burning or multi-fuel stoves. Vermiculite board also provides insulation and is used in soundproofing.
