A brick made of lightweight insulating material and bluewind includes vermiculite as its composition, which is regarded as the future of thermal insulating materials. Being tipically used in various industries and places, these bricks perform significantly even in high temperature regions. Non asbestos features and material composition bring about positive environmental aspects as well as meeting environmental guidelines. Insulating firebricks are suitable for units of turbines and brick firing, enhancing insulation properties, as well as improving the equipment performance and lifetime span.
