The Insulating Fire Brick (IFB) is a type of soft brick made of refractory ceramic material, a blend of alumina and silica, that can withstand extremely high temperature applications and has a low thermal conductivity. This IFB is an excellent insulator and reflects heat well.
Insulating Refractory Fire Bricks are light in weight and can be easily cut by handheld hack saw or any other hand tool like chisel or drill. They are ideal for creating custom shapes and cavities.
IMPORTANT: Do not confuse this lightweight Insulating Fire Brick (IFB) with the dense Firebrick. Hard Firebricks are much heavier, harder and difficult to shape. Insulating Fire Bricks are softer, much better insulators, and easier to shape. For example a 1.25″ thick 2300F rated IFB weights only 1.2 lbs. The same size hard firebrick weights almost 4 lbs.
