Insulating foam bricks:
It is a type of refractory brick with low thermal conductivity and a porous structure.
Porous refractory bricks have a small density of about 0.4 - 1.6 g/cm3 and a relatively high porosity: 50-58%, used in industrial furnaces, for insulation purposes, reducing heat to the environment. outside.
