Description
Light Weight Fire Clay Insulation Brick – B1/B2 Series for Boiler Furnace Lining
Our B1/B2 series Light Weight Fire Clay Insulation Brick is a premium refractory material engineered for superior thermal management in high-temperature industrial environments, particularly in boiler insulation and furnace lining. Manufactured from super-pure raw materials with strictly classified fillings, our bricks significantly reduce structural load and heat storage while maintaining excellent thermal shock resistance and long service life.
With a standard size of 230*114*65mm, low bulk density (0.60-1.25 g/cm³), and working temperatures from 900°C to 1600°C, our lightweight insulation bricks provide a cost-effective solution to reduce fuel consumption, construction costs, and furnace downtime.
