IFB23 Insulating Fire Brick

CCEFIRE® IFB23 Insulating Fire Brick is a lightweight mullite-based insulating refractory brick designed for thermal insulation in industrial furnaces and high-temperature equipment. The brick is manufactured using high-purity refractory clay as the primary raw material. Carefully graded organic pore-forming additives are incorporated during production to create a uniform and controlled porous structure during high-temperature firing.
This engineered porous structure provides the brick with excellent thermal insulation properties and low thermal conductivity, allowing it to deliver reliable insulation performance in medium- to high-temperature industrial furnace environments.

Due to its lightweight porous structure, IFB23 insulating fire brick features low bulk density and low heat storage capacity, which helps reduce furnace heat loss and improve overall thermal efficiency. All six faces of the brick are precision machined to ensure tight dimensional tolerances, making installation easier while reducing the amount of refractory mortar required. This contributes to the formation of a stable and uniform furnace lining structure.

CCEFIRE® IFB23 insulating fire bricks also support Fabrication and custom refractory component manufacturing. The bricks can be processed according to customer drawings to produce specialized furnace components such as burner blocks, support bricks, insulation structures, and custom refractory assemblies. Through Fabrication processing, refractory materials can better match specific equipment designs, improving installation efficiency and optimizing furnace lining performance.

With good thermal stability and excellent thermal shock resistance, CCEFIRE® IFB23 insulating fire brick maintains structural integrity even under high-temperature operating conditions, making it a commonly used material for furnace insulation structures and custom refractory components in industrial equipment.
