There is a clear distinction between lightweight insulating bricks and fire bricks in terms of their application. Firebricks are meant for high temperatures while providing structural stability, on the other hand, lightweight insulating bricks are meant for maintaining thermal efficiency. Bluewind’s product based on non-asbestos expanded silver vermiculite has an even porous structure which provides effective insulation. Therefore, it is suitable as a transition refractory lining or as backup insulation replacing light weight insulating brick, increasing the performance of an industrial furnace greatly.
