Insulating Fire Bricks- Grade 28. Rates to 1530oC (2800oF). Size: 230x114x76mm. Density: 900kg/m

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.

  1. What is a Kiln? Construction and application The words kiln derived from old English cyln and furnace are often used interchangeably to describe a type of oven / stove which is heated to a very high temperature referred to as a firing process. According to the strict definition the difference is that a kiln is loaded when cold and then heated up whereas a furnace is heated up first before being loaded.
  2. What is Insulation and How It Works What is Insulation and How It Works Insulation is an important aspect of any high heat appliance, whether it is in your home or in industrial settings. When an appliance is properly insulated, it has many additional benefits conferred on it, i.e. it reduces heat loss which thus saves on energy consumption and as a result, is more environmentally friendly and more economically efficient. In the long term, this increases the life span of such appliances as they require less frequent
