Product Description

Laurel Calcium Silicate Board remains a white and hard high temperature thermal insulation material that is lightweight due to its composition of calcium silicate, possessing properties of high strength, low thermal conductivity, and pressure resistance.

Laurel CS-Board can be categorized into three different types based on their working temperature: 1000 Grade CS Board, 1100 Grade CS Board, and Waterproof Calcium Silicate Board, in addition to 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.
