FURNACE METTALIKS offers most extensive range of insulation firebrick products, and access to unparalleled expertise in thermal engineering and furnace design. Their lightweight, precision-made insulating firebricks help our customers to reduce their operating costs by saving energy.

All their insulation 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
  • 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
