The bluewind vermiculite lightweight insulating brick serves a distinct purpose as it is engineered for the purpose of being used in industrial furnaces while dealing with high temperatures. Its inclusion of non asbestos expands silver vermiculite makes it possible for the composition of the controlling and uniform pore structure to be used in order to effectively act as an insulator. These bricks can easily be lined for transition or refractorily as back up insulation to improve the way the industrial furnace works and can make it last longer. The ultimate low thermal mass performance of our heating performing fire bricks is made possible through advanced manufacturing techniques involving compression and sintering under extreme temperatures.
