Cellar Aluminum
1 / 5
Calcium silicate board for thermal insulation is made of xonotlite and reinforced glass fiber. It is resistant to high temperatures up to 1100 ºC, offering excellent heat insulation, low bulk density, and high strength. It is a white, hard microporous material widely used in industrial furnace insulation, providing durability and chemical stability.
Widely utilized for thermal insulation and fire prevention in electric power, metallurgy, petrochemical, and shipbuilding sectors. High-density versions are specifically developed for non-ferrous industries for the casting and molding of molten aluminum, benefiting from non-stick characteristics and precision CNC machinability.
