Product Description

Laurel Calcium Silicate Board is white and hard high temperature thermal insulation material based on lightweight calcium silicate with high strength, low thermal conductivity,pressure-resistant characters.

It can be used at most different areas of industry as back-up insulation. In particular for the construction of industrial furnaces, dryers and apparatuses but also in the cement and petrochemicals industries, it is the classical cost efficient insulating material.

According to the different working temperature,Laurel CS-Board can be divided with Three type of products:1000 Grade CS Board、1100 Grade CS Board,Waterproof calcium silicate board and Laurel High Density CS Board.

Regular dimension for Calcium Silicate Board:

600x300mm;450*250mm;1000*500mm;1200*610mm,or any other customized dimension as required.
