insulating fire brick
REFRAMAT 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
