Ceramic fiber boards | Aluminum silicate wool boards

Show high temperature resistance in continuous use at temperatures up to 1400°C.

Ceramic fiber board | aluminum silicate wool board is a special high temperature insulation board, heat resistant up to 1260°C/ 2300°F or with addition of zircon up to 1400°C / 2552 °F, in various densities. The board is made of special ceramic fiber blends and is a vacuum-formed product characterized by lightness combined with hardness and excellent strength. It does not retain heat and has low thermal conductivity at high temperatures. It is very easy to cut, shape and shear, which makes the construction and installation very fast and easy.
