Insulation Furnace Lining Bricks
,Furnace Lining Bricks Lightweight
,B2 Fireclay Brick
Our lightweight fireclay insulation bricks are widely used in furnaces, kilns, chimneys, and pizza ovens. With service temperatures up to 1400°C, they provide excellent thermal insulation, energy efficiency, and long service life.Available in standard and customized shapes, these bricks feature a low bulk density of 0.60–1.25 g/cm³, working temperatures from 900°C to 1600°C, and good thermal shock resistance.
