Wedge India offers best quality Calcium silicate blocks in Size 600 X 100 X 75 mm at low price INR 124 / Pc density 250 - 260 Kg/M3 for thermal insulation in industrial applications due to their excellent insulating properties, high-temperature resistance, and durability.


These blocks are ideal for use in high-temperature environments, such as furnaces, boilers, and other industrial equipment. Here’s a detailed overview of calcium silicate blocks with a 75 mm thickness for thermal insulation:

Properties of Calcium Silicate Blocks


Thermal Insulation

Low Thermal Conductivity: Calcium silicate has a low thermal conductivity, typically in the range of 0.05 to 0.1 W/m·K, which makes it an excellent insulator for high-temperature applications.

Consistent Performance: Maintains its insulating properties over a wide range of temperatures, ensuring reliable performance.


High-Temperature Resistance

Service Temperature: Can withstand temperatures up to 1100°C or higher, making it suitable for insulating hot surfaces.

Thermal Stability: Remains stable and does not shrink or crack under high temperatures.


Durability and Mechanical Strength

High Compressive Strength: Provides good mechanical strength, typically in the range of 5 to 10 MPa, which ensures durability under mechanical stress.

Impact Resistance: Resistant to physical damage, ensuring a long service life.


Moisture Resistance

Hydrophobic Properties: Often treated to be hydrophobic, which helps resist moisture absorption and maintain insulating properties even in humid conditions.

Dimensional Stability: Maintains its shape and size even when exposed to moisture.



Fire Resistance: Non-combustible and does not contribute to the spread of fire, providing additional safety in industrial applications.



Industrial Furnaces and Kilns

Used to line the walls, floors, and roofs of industrial furnaces and kilns to retain heat and improve energy efficiency.

Boilers and Steam Pipelines

  • Insulates boilers and steam pipelines, reducing heat loss and improving the efficiency of steam systems.

Petrochemical and Chemical Plants

  • Insulates equipment and piping in petrochemical and chemical plants, providing both thermal insulation and fire protection.

Power Plants

  • Used in power plants for insulating turbines, boilers, and other high-temperature equipment.

Foundries and Metal Processing

  • Insulates ladles, tundishes, and other equipment in foundries and metal processing industries.

Installation Considerations


Benefits of Using 75 mm Thick Calcium Silicate Blocks

Enhanced Thermal Insulation

A 75 mm thickness provides substantial thermal resistance, significantly reducing heat loss and improving energy efficiency.


Reduces the need for additional layers of insulation, potentially lowering installation and material costs.

Space Efficiency

Provides high levels of insulation without requiring excessive space, making it suitable for applications where space is limited.

Improved Safety

Enhances safety in high-temperature environments by reducing surface temperatures and minimizing the risk of burns or heat-related injuries.


Calcium silicate blocks with a 75 mm thickness are a highly effective solution for thermal insulation in high-temperature industrial applications. Their low thermal conductivity, high-temperature resistance, durability, and ease of installation make them a preferred choice for insulating equipment, piping, and structures in various industries.
