High alumina insulation bricks are a special type of brick that can handle high temperatures and act as insulation. Insulation bricks are used to line fireplaces, fireboxes, furnaces, and kilns. It is designed to withstand temperatures of up to 1760℃ while conducting very little of that heat to provide a greater level of energy efficiency.
High alumina insulation bricks also called lightweight high alumina bricks, are a special type of brick that is basically for preserving or insulating heat.
High alumina insulation bricks are used to line fireplaces, fireboxes, furnaces, and kilns. Commonly, this kind of brick is not exposed to direct fire inside kilns or furnaces, it only be constructed in the medium layer as insulations. It is a good heat insulation material, which has high compressive strength, low thermal conductivity, and good insulation quality. The bulk density of JM series lightweight heat-insulating brick is 0.6~1.25g/cm3. Working temperatures range from 1300℃ to 1600℃.
Insulation refractory bricks are refractory bricks or blocks, of a ceramic material that is commonly used in a variety of different applications including fireboxes, all types of furnaces, melters, and industrial kilns.
1. Good insulation quality.
2. High strength.
3. Low thermal conductivity.
4. Low impurity.

The lightweight and high insulation value of our bricks make possible thinner furnace walls, improved efficiency, and lower operating costs.
The high compressive strength of IFB allows for self-supporting structures at elevated temperatures. IFBs are compatible with dense fire bricks and add strength to the whole construction.
Lower heat storage versus dense brick means reduced fuel costs and faster heat-ups in cyclically operated heating equipment.
We are low in impurities such as iron, which can adversely affect refractory performance in many applications. They are used in many furnaces with controlled atmospheres.
Because our insulation refractory bricks are machined to precise dimensions, courses can be laid quickly and easily, and the result is a stronger, tighter refractory lining resulting in less heat loss through the joints.
