Skyline Components supplies insulating firebricks (IFB) for use at high temperature up to 3200 °F. They are made from refractory clays and other materials, but don’t contain any organic materials. Because of their porous structure, the materials have excellent thermal insulation properties. Insulating firebricks are soft and light in weight. They can be easily cut by handhold saw or any other hand tool like chisel or even drill bit. They can be used as hot face refractory linings or as back-up insulation behind other refractory materials in furnaces, ovens, stoves and kilns heated up with either electric spiral elements or gas burners.
