Insulation Products

We offer quality material for manufacturing and supplying insulation products with high durable and reliable features. We provide Insulation Products such as Insulating Bricks of Hot and Cold Face grades, Insulating Castables, Mica Insulating Bricks, Calcium Silicate Bricks and Cer-wool Ceramic Fiber Products. While the majority of insulation in buildings is for thermal purposes, the term also applies to acoustic insulation, fire insulation, and impact insulation. These insulation materials that provide outstanding insulation in areas that require no electrical or thermal degradation.

Calcium Silicate Bricks

The Calcium Silicate Bricks is a rigid material with high compressive strength and low shrinkage at high temperature. These are non-asbestos Calcium silicate insulation boards as well as pipes. These coverings are made to resist chemicals, resist high temperature are light weight are low thermal conductivity and so on. It is used in roads, insulation, bricks, roof tiles, table salt and occurs in cements, where it is known as belite. Our ideal product, Calcium Silicate Insulation Board has the highest bulk density and has very high compressive strength too.
