This grade of IFB is produced to meet specific thermal and physical requirements. These firebricks are made from high-purity refractory clays, with graduated additions of alumina for the higher temperature products. and a carefully graded organic filler, which burns out during manufacture to give a uniform, controlled pore structure.

Each brick is machined to precise tolerances on all six faces.


Low thermal conductivity - Gives good thermal insulation, enabling the use of thinwalled constructions.

Low heat storage - Due to their light weight and low thermal conductivity, These bricks absorb minimal heat, giving significant energy savings in cyclically-operated kilns. The accurate dimensions - Enable the bricks to be laid more quickly, with thin, uniform joints, allowing the construction of strong and stable  structures.


Recommended for use as a primary hot face refractory lining or as back-up insulation behind other refractories in furnaces, kilns, flues, refining vessels and heaters, regenerators, gas producers and maine also offer a cutting service on all of our refractory materials please.
