Insulating Fire Bricks are a special type of brick that can handle high temperatures and act as insulation. Insulating firebrick is used to line fireplaces, fireboxes, furnaces and kilns. It is sometimes referred to as “refractory brick” and is designed to withstand temperatures of up to 1760°C while actually conducting very little of that heat in order to provide a greater level of energy efficiency.
Insulating firebrick is a refractory brick or block, of a ceramic material that is commonly used in a variety of different applications including fireboxes, all types of furnaces, melting and industrial kilns.
