Insulating Firebricks, features include:

·Excellent strength at ambient and elevated temperatures

·High compressive strength

·Every brick ground to precise dimensions

·Very low levels of iron and other impurities (especially for resistance to reducing atmosphere conditions)

·Lower heat storage than denser refractories

·Available in custom designed shapes upon request 

Firing, benefits include:

·Two high brick stack provides even heat penetration into brick

·1350°C – 1370°C (2460°F - 2500°F) for K-23 and up to 1400°C (2550°F) for K-25/K-26

·Stable Anorthite Phase formed

·Superior against alkali attack – Na and K

·Thermally stable at very high temperatures

·High hot strengths

Insulating Firebricks, benefits include:

·Energy saving benefits

·Lower operating costs

·Lightweight, energy-saving nature results in less heat loss and allows for thinner furnace linings

Insulating Firebricks (IFB’s) are well established products for solving many problems of high temperature heat containment in industries ranging from ceramic production kilns to anodes for primary aluminum.
