Superior Grade High Temperature Ceramic Insulation Products

CeramSource, Inc., top ceramic fiber insulation suppliers, provides a complete range of insulating ceramic firebrick (IFB) that offers unsurpassed performance and value for a wide variety of industries and applications. Different grades of insulating ceramic firebrick are manufactured according to international standards, and are suitable to operate in various temperatures and atmospheres up to 3000º F.

Features of Insulating Ceramic Firebrick (IFB):

  • Excellent strength at ambient and elevated temperatures
  • High compressive strength
  • Every brick ground to precise dimensions
  • Very low levels of iron and other impurities
  • Lightweight and energy-efficient
  • Lower heat storage than denser refractories
  • Heats quickly and economically to operating temperature
  • Cools fast to speed periodic operations

Our insulating ceramic firebrick can be used in residential, commercial, and industrial applications. It is made to withstand high temperatures and has low thermal conductivity. When using ceramic firebrick in industrial purposes, you may require porosity or thermal conductivity in order to meet a certain requirement. This can be adjusted by adding or changing the volume of refractory materials.

Some uses for our insulating ceramic firebrick:

  • Lining Kilns
  • Insulating Ovens
  • Insulating Furnaces
  • Fireplaces
  • Fireboxes

Temperature Range:

  • IN-23: Maximum service temperature of 1260 °C (2300 °F)
  • IN-26: Maximum service temperature of 1427 °C (2600 °F)
  • IN-28: Maximum service temperature of 1538 °C (2800 °F)
  • IN-30: Maximum service temperature of 1649 °C (3000 °F)
