Density 1020 kg/m³ · High Density · Industrial Grade
1020 kg/m³ calcium silicate board is a high density thermal insulation material designed for industrial furnaces and demanding high temperature environments. It provides improved compressive strength, dimensional stability and reliable insulation performance.

Material
A high-density grade with higher mechanical strength, better resistance to installation impact and strong thermal stability — a dense, dimensionally stable board for the most demanding furnace and metal-contact positions.
