Insulating fire bricks

THERMObrick-LD bricks is the group of products with a low-densities and high qualities for industrial furnaces and thermal plant units. THERMObrick-LD insulating fire bricks are grinded at all sides to the required dimensional precision and are stable in terms of shape geometry along with less weight.

Because of the thermal, chemical and mechanical properties, THERMObrick-LD bricks are suitable for multiple applications for hot face and back-up layers. The low thermal conductivity enables significantly energy savings of refractory systems. THERMObrick-Isol insulating bricks are typically to be used for back-up layers. These products are characterized by excellent thermal insulation properties, very low weights as well as moderate classification temperatures and mechanical strengths.

Advantages of insulating fire bricks

What are the advantages of THERMO bricks for industrial furnaces and Thermal plant units:

  • Well sintered materials
  • Less shrinkage
  • Wide range of different materials
  • Moderate mechanical strength
  • Thermal shock resistance
  • Less thermal conductivity
  • Less thermal heat capacity
