The Best Solution For Your Specific Needs
Insulating fire bricks characteristics and advantages:
1. Insulating fire bricks has Lower content of iron, alkaline and impurities, good high temperature properties.
2. Insulating fire bricks has homogeneous structure, light weight, energy saving because lower heat storage in the furnace during cooling cycles.
3. Insulating bricks has High strength, good thermal shock resistance under high temperature.
4. Insulating bricks has Precise sizes due to grinding and shaping after firing, which meets the requirement of construction.

More porosity brings excellent insulation effect,energy saving.
Low content of iron, alkaline and metal impurities.
High crushing strength under thermal state, volume stability.
Precise brick size by machining, cutting and grinding special shapes, expediting bricklaying.
Little thermal storage when absorb more heat, energy saving effect is obvious.
