What is a Calcium Silicate Board?

Calcium Silicate Board (CaSi Board) is an asbestos-free, high-temperature insulation material made from silica, lime, and reinforcing fibers. It combines low thermal conductivity, high fire resistance, and good mechanical strength for industrial and building applications.

What sizes and quantities are available for 600×150×100 mm boards?

For the 600×150×100 mm size, Wedge India currently lists a bulk lot of 322.2 CBM and a small lot of 3 CBM for quick dispatch. Custom volumes can be arranged on request.

What is the maximum service temperature of Wedge CaSi Boards?

Depending on grade and density, Wedge Calcium Silicate Boards are suitable for continuous service around 650–1100 °C and short-term exposure up to 1200 °C.

Where are Calcium Silicate Boards used?

Typical uses include furnace and kiln backup linings, ladle covers, cyclones and preheaters (cement and glass), reactors and reformers (petrochemical), as well as fire-rated partitions and duct insulation in buildings.

What are the advantages of CaSi Boards?

Advantages include low thermal conductivity, Class A1 non-combustibility, high strength and vibration resistance, moisture and chemical resistance, and easy machinability for custom parts.

Are Calcium Silicate Boards asbestos-free?

Yes. Wedge India supplies 100% asbestos-free Calcium Silicate Boards suitable for industrial and building environments.

Can these boards be customized into shapes?

Yes. Boards can be cut and machined into pipe supports, launders, spouts, floats, hot-top rings, and other custom refractory components.

How is the thermal conductivity performance?

Typical thermal conductivity is about 0.06 W/m·K at 200 °C and around 0.18 W/m·K at 800 °C, varying by grade and density.

Are Calcium Silicate Boards resistant to molten metal?

High-density grades are non-wettable to molten aluminium and are commonly used in casting applications such as launders and holding furnaces.
