Bluewind Vermiculite Light-weight Insulating Firebrick has been specially developed for usage in high temperatures. The process of high temperature sintering in turn improves the brick strength enabling it to be used in the more demanding industrial settings. A porosity controlled structure of the brick enhances the insulation while improving the thermal efficiency which are needed features for their use in many furnace constructions. With greater amount of heat withstanding capability and thermal shock resistance capabilities, our firebrick enhances operational capacity and lowers energy cost.
