Porosaite Brick / Insulation Brick

Insulation bricks, also known as porosaite bricks, are lightweight refractory bricks designed to minimize heat loss through furnace walls. Their porous structure traps air, creating an effective thermal barrier that reduces energy consumption significantly.

These bricks are typically used as a backup lining behind the main refractory layer. By preventing heat from escaping, they help factories reduce fuel costs and maintain more consistent operating temperatures inside the furnace.

Our insulation bricks are available in various grades to match different temperature requirements. They are an essential component in any energy-efficient furnace design.
