Product Description

Laurel Calcium Silicate Board is a white and hard thermal insulation material that withstands high temperatures. It is made from lightweight calcium silicate and possesses properties such as high strength, low thermal conductivity, and pressure-resistance.

Laurel CS-Board can be classified into three types of products based on their working temperature, namely: 1000 Grade CS Board, 1100 Grade CS Board, Waterproof Calcium Silicate Board, and Laurel High Density CS Board.

The usage of it is extensive in thermal insulation and fire prevention for equipment and pipelines in the fields of electric power, metallurgy, petrochemical, and ship-building, as well as in heating pipe network systems.

Regular Dimension for Calcium Silicate Board:

  • 600x300mm;
  • 450*250mm;
  • 1000*500mm;
  • 1200*610mm,

or any other customized dimension as required.
