  • Complete range of IFB products
  • Network of global distribution
  • Experienced Technology Center dedicated to IFB innovation and technical support in the industry

Our lightweight, precision-made firebricks, insulating firebricks and roof blocks help our customers to reduce their operating costs by saving energy. All our insulating firebricks are made from high-purity refractory clays with graduated additions of alumina for the higher temperature-rated products.

Our Insulating Firebrick features include:

  • Excellent strength at ambient and elevated temperatures
  • High compressive strength
  • Every brick ground to precise dimensions
  • Very low levels of iron and other impurities (especially for resistance to reducing atmosphere conditions)
  • Lower heat storage than denser refractories
  • Available in custom designed shapes upon request

Benefits from our manufacturing and firing process include:

  • Two high brick stack provides even heat penetration into brick
  • 1350°C – 1370°C (2460°F - 2500°F) for K-23 and up to 1400°C (2550°F) for K-25/K-26
  • Stable Anorthite Phase formed
  • Superior against alkali attack – Na and K
  • Thermally stable at very high temperatures
  • High hot strengths

Our comprehensive range of JM, K and TJM IFBs are well established products for solving many problems of high temperature heat containment in industries; ranging from ceramic production kilns to anodes for primary aluminium.
