Product Description
Insulating bricks characteristics and advantages:
1. Insulating bricks has Lower content of iron, alkaline and impurities, good high temperature properties.
2. Insulating 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.
