Lightweight clay insulation bricks are high-quality insulation materials. It can be used in the kiln to achieve rapid heating and cooling, reduce the weight of the furnace body, save fuel, and reduce production costs.

A brief introduction to lightweight clay insulation bricks

Lightweight clay insulation bricks have high porosity, which can reach 40-85%, have a porous structure, and strong thermal insulation.
