Insulating firebricks are made using a method which results in a porous, lightweight structure. This is important in processes where the work is heated and it is not desirable to waste energy heating the brick work for example in forges and annealing kilns. We recommend using Vitset 45- refractory mortar for setting Grade 28 insulation bricks.


  • Insulating firebricks are often used in ceramic kilns for faster turnaround and also because of their low iron content.
  • Insulation bricks are used as an additional layer behind other refractory linings in furnaces, kilns, treatment vessels etc.
  • They are used in glass and enamel furnaces in areas not in contact with the molten product.
