Insulation blocks are available in Firebird, which require no mortar joints to produce sizes up to 610*500*100mm. These blocks give furnace designer more choices on specific area to reduce mortar joints and significant fuel & labor savings.

A large scale machine shop at the factory is capable of supplying accurate machined shapes. Single brick tolerance is within +/-1mm while pre-assembled tolerance can be strict controlled according to drawings.

Firebird insulation blocks are divided into:
a. FJM23, FJM26, FJM28 grade according to ASTM standard;
b. High strength insulation blocks with CCS reach 10MPa

Typical Application

Glass furnace sidewall and bottom insulation, port insulation, tin bath roof, etc.
Ceramics roller kiln, tunnel kiln, pusher kiln, etc.
Other industrial furnaces where less mortar joint is required.

Firebird Silica Insulating Firebricks choose high purity silica sand as main raw material, adding porous material to create small pores, dry pressed or extruded to shape, sintered at high temperature and grinding to shapes.

Typical Application

Our silica insulating firebricks enjoy the characters such as:
● Density low to 0.6g/cm3, ideal material for energy saving
● High refractoriness under load, similar to dense silica brick
● Strong acid-resistant slag erosion
● Good high temperature mechanical strength
● Low thermal conductivity
● Less residual quartz;
● Accurate dimension tolerance

Microporous Board is composed by fine powder and fibrous materials, and formed by special compressing process. The average pore size is equal to or less than the mean free path of air molecules at standard atmospheric pressure. So the board has a lower thermal conductivity than the still air, which is ideal high temperature insulation material. The board have certain strength and can be covered by aluminum foil or PE foil.

Typical Application

Backup insulation in industrial furnace or equipment, such as ceramic kilns, glass furnace, feeding machines and chemical plants. Insulation for ladle and casting equipments.
