Bubble Alumina Brick and Insulating Firebrick are high temperature refractory brick, max temp 1800 deg C, used in furnace kiln.

Bubble Alumina Brick and Insulating Firebrick are high temperature refractory brick.

Bubble Alumina Brick. We stock in both 2.5 & 3” sizes. We also carry double bump interlocking anchor styles. For use up to 1800C, these brick have excellent insulating properties as well as high hot strengths.

Insulating firebrick, we carry produces thirteen types of Insulating Fire Brick for use in applications from 2,000°F (1,093°C) to 3,200°F (1,760°C). Each type is formulated to meet specific thermal and physical requirements and after firing is machined to precise tolerances.

Made from high purity refractory clays and other ceramic raw materials, these insulating fire brick contain a carefully graded organic filler which is burned out during manufacture to give a uniform controlled pore structure.

Advantages of bubble alumina brick.

High Insulating Va

The high compressive strength of bubble alumina brick allows for self-supporting structures at elevated temperatures. Insulating fire brick are compatible with dense fire brick and add strength to the whole construction.

Low Heat Storage

Lower heat storage versus dense brick means reduced fuel costs in cyclically operated heating equipment. lue

The light weight and high insulating value of refractory brick make possible thinner furnace walls, improved efficiency and lower operating costs.

Strong

The high compressive strength of bubble alumina brick allows for self-supporting structures at elevated temperatures. Insulating fire brick are compatible with dense fire brick and add strength to the whole construction.

Low Heat Storage

Lower heat storage versus dense brick means reduced fuel costs in cyclically operated heating equipment.
