Bluewind Vermiculite Light-weight Insulating Brick is a very well designed product which is effective in diverse and harsh industrial environments. It is manufactured of a non-asbestos expanded silver vermiculite which gives the brick exclusive qualities of insulation as well as thermal stability. These, combined with its controlled pore structure, greatly increase the brick's resistance to high temperatures, allowing it to be employed within a wide range of commercial furnaces. We apply application techniques which ensure that such bricks perform efficiently so that the life of your equipment increases while its energy use becomes more effective.
