We offer B1 and B5 insulation bricks, and also other thermal insulation bricks.These thermal insulation bricks are made from different raw materials such as diatomite, clay, high alumina powder, mullite, silimanite and etc. Porous structure makes them own lower density and lower thermal conductivity. They are widely used for heat-insulating purpose in many kinds of industrial furnace, electric furnace and metallurgical stove.

The main type we offer JIS series: A1, A2, A3 to A7; B1, B2, B3 to B7; & C1, C2, C3; the standard size is 230*114*65mm and 230*115*76mm.
