B-1 Insulating firebrick

 Insulating fire bricks prevent the heat of the furnace from outgoing outwards because of excellent heat insulation and high quality insulating frie bricks save money in two ways.First,we can bulid thinner and therefore cheaper but still safe refractory walls at a lower installation cost.Secodly,insulating prevents heat wastage and so enables the refractory to operate on less fuel and save energy.
