Fire Clay Insulation Brick is a lightweight refractory product made from high-purity fireclay and other insulating materials. It is specially designed for high-temperature environments where heat retention, low thermal conductivity, and energy efficiency are essential. These bricks provide excellent insulation performance, reduce heat loss, and improve furnace efficiency, making them ideal for both hot-face and backup lining applications in industrial furnaces, kilns, and incinerators.
