Leadsun supplies several grades of insulating fire brick for use in applications ranging from 1260 °C to 1760 °C. Each grade is formulated to meet specific thermal and physical requirements. After firing, every brick is machined to close dimensional tolerances.
Insulating bricks are manufactured using exceptionally high-purity clays and other ceramic materials. Carefully graded organics used during the manufacturing process burn out during firing to create a uniform pore structure.
