Insulation bricks are lightweight and not very dense. They can either see the hot face of the kiln or be used behind another layer as insulation. Low weight, high solidity and low heat conductivity are the special features of insulation bricks that make them matchless in all perspectives. Light Weight Fire Insulating Bricks are being used in all types of furnaces, boilers etc. for heat insulation. We are capable of supply in large quantity to our valued customers in a very cost effective manner.
Where it is used ?
Insulation bricks are generally used in electric and gas kilns where there is minimal abrasion against the lining of the kiln.
