Refractory bricks
Insulating fire bricks
Lightweight refractory bricks that act as a thermal barrier. With low conductivity, insulating fire bricks keep heat inside the equipment and reduce energy use.

What are insulating fire bricks?
They are light, porous refractory bricks made to insulate. Unlike dense bricks, their main job is to reduce heat loss and improve the structure's thermal efficiency.
Refratários Recife supplies the high-performance grade, up to 1,400 °C. In many projects both types work together: dense bricks on the hot face and insulating bricks as the outer layer.
