Brief introduction of fire clay insulation bricks

Light fire clay brick is a kind of thermal insulation material with high porosity, low bulk density and low thermal conductivity. Lightweight insulating bricks are characterized by porous structure (porosity is generally 40% to 85%) and high thermal insulation.
