Insulating Firebricks provide lightweight and low thermal conductivity, low heat storage capacity and high strength and they save heat consumption. They can be used as the heat insulation or no-melt erosion parts of the working layer suitable for use in hot face refractory linings or as back-up insulation in all types of high temperature processing of metals, petrochemicals as well as ceramics in foundry furnaces and large tunnel kilns.
