Calcium Silicate Board 
High-Temperature Thermal Insulation (rated to 1100 °C) – Sold per board

Rigid, lightweight calcium silicate board engineered for demanding thermal environments. It delivers low thermal conductivity and stable performance at elevated temperatures, making it suitable for both industrial and commercial insulation projects. Explore complementary options in our High Temperature Boards collection or our broader Thermal Insulation Materials range.

Key Features:

• High temperature resistance — maximum service temperature 1100 °C
• Low thermal conductivity — helps reduce heat loss and energy consumption
• Moisture resistant — suitable for humid conditions when correctly installed
• Dimensionally stable under heat — minimises warping or shrinkage
• Non-combustible — appropriate for fire-rated systems (check system requirements)
• Easy to work — can be cut and machined with standard tools

Typical Applications:

• Furnace and kiln linings (as part of a refractory system)
• Wood-fired pizza oven base insulation
• Refractory back-up insulation and heat-shielding
• High-temperature duct and equipment lagging
• Thermal barriers in industrial plants
