SILICA BOARD・SUPER BOARD

Home > Products > Insulation Firebrick > SILICA BOARD・SUPER BOARD

Calcium Silicate Board is a large-sized material which has superior thermal insulation and workability (processability) compared to insulating firebricks.

Two types of boards available:

■Silica Board for 650°C

■Super Board, Super Board L, Super Board H for 1000°C

Super Board : Standard Super Board L : Lightweight

Super Board H : Mechanically strong

Characteristics

Heat Resistance

Long and reliable service life within the maximum operating temperature.

Workability

Improved work efficiency due to good workability and light weight.

Thermal Insulation and Energy Saving

Comperably lower thermal conductivity than that of insulating bricks. High thermal insulation properties allow the reduction of furnace wall thickness.

If the furnace wall thickness is kept the same, the amount of heat-loss can be further reduced, resulting in energy savings, while also lowering the cold face temperature.

Its bulk density is lower than that of insulating bricks. The low bulk density helps reduce the amount of thermal energy stored in the furnace materials.

Lowered thermal capacity is expected to reduce the amount of energy required to raise the furnace temperature.

Specifications

Depending on the application, the following products are also available: surface-water-repellent products and overall-water-repellent products (Super Board and Super Board L).
