One of the interesting specifications of bricks is that they must be able to withstand high ferrous which is crucial for furnaces systems. The low density and high thermal resistance that Bluewind Vermiculite Insulating Firebrick possesses, makes it an effective option. These units have their make up designed to be lightweight to decrease weight loading on furnace constructions while keeping in mind thermal insulation properties. Their composition and chemical manufacturing ensure that the pores are of unidirectional structure, boosting overall intensity of bricks in high temperatures.
