Among all the insulating materials, the light Bluewind Vermiculite insulating Firebrick has the greatest thermal insulation. Therefore, this is the preferred type among the industrial furnaces for expansion. Expanded silver vermiculite has formed a unique characteristics controlled pore structure which makes the insulation better. This product not only helps to reduce energy use but also enhances the safety of the operations of the furnace by ensuring it is maintained at the required temperatures. Our firebricks are designed to withstand the extreme conditions which are characteristic of different sectors without impairment or loss in performance under different conditions.
