Refractory Insulation Bricks
Energy conservation has
always been a major concern for all industries. Our Insulation Bricks are
the solution to industries operating at high temperatures. Low weight, high
solidity and low heat conductivity are the special features of Insulation
Bricks. Insulation Bricks are used in all types of furnaces and boilers for
heat insulation. Currently we supply Insulation Bricks with service
temperatures ranging from 1000˚C to 1430˚C. We supply Insulation
Bricks in standard size and special shapes as well. Packing of the bricks
is done in cardboard boxes. We are constantly researching on Insulation
Bricks to get better quality in terms of lower density with higher service
temperatures.
