High Alumina Insulating Bricks

High alumina insulating refractory bricks are a special type of brick that can handle high temperatures and act as insulation. Insulating bricks are used to line fireplaces, fireboxes, furnaces, and kilns. It 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.

Introduction of High Alumina Insulating Bricks

Applications of High Alumina Insulating Bricks

Insulating 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.

Advantages of High Alumina Insulating Bricks

High Insulating Value

The lightweight and high insulating value of our bricks makes possible thinner furnace walls, improved efficiency, and lower operating costs.
Strength

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.
Low Heat Storage

Lower heat storage versus dense brick means reduced fuel costs and faster heat-ups in cyclically operated heating equipment.
High Purity

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.
Accurate Dimensions

Because our Insulating 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.
