ISOTEK™ Insulating Firebricks
As specified by name, Insulating firebricks are of light weight, low
thermal conductivity, excellent strength at ambient and elevated
temperature. With very low levels of iron and other impurities, the bricks
provide good resistance to chemical attach, can be used in tough, reducing
atmosphere conditions. Every brick is ground to precise dimensions.
