Firebrick and Insulating Firebrick Solutions

We offer the most extensive range of insulating firebrick products in the world, and access to unparalleled expertise in thermal engineering and furnace design. Our lightweight, precision-made insulating firebricks help our customers to reduce their operating costs by saving energy.

Insulating Firebrick

All our insulating firebricks are made from high-purity refractory clays with graduated additions of alumina for the higher temperature-rated products. Carefully graded organic fillers burn out during firing to give a uniform, controlled pore structure with: 

  • Excellent strength at ambient and elevated temperatures
  • Outstanding insulating values across the temperature range
  • Lower heat storage than denser refractories
  • Very low levels of iron and other impurities
  • Low reheat shrinkage 

Our insulating firebrick products are suitable for use in hot face refractory linings or as back-up insulation in all types of high temperature processing of metals, petrochemicals and ceramics including: 

  • Primary processing furnaces for fabrication and forging of ferrous metals
  • Roller hearth, reheating and forging furnaces for ferrous and non-ferrous metals
  • Blast furnaces and host blast stoves for carbon bake ovens
  • Flues, refining vessels and reactor chambers used in petrochemical processing
  • Ceramic kilns used by manufacturers of sanitary ware, glass ware and building products
  • Hobby and laboratory kilns
  • Rotary lime kilns
  • Fireplaces 

We have the expertise to advise on the optimum insulating firebrick products for your application, and we also offer furnace design services. Contact us to learn more about how we can help improve your high temperature process and save energy.
