Insulation Brick

Specification of Insulation Brick

Because the refractory bricks are spread out heat then required protective material that can inhibit the propagation of heat. For this reason when installing fire bricks, add insulation bricks behind it so that the temperature in the combustion chamber is maintained constantly.
