IFB is an excellent high temperature insulation product, and offers both insulating properties and load bearing ability. IFBs are suited to applications above 1000°C (1832°F) and particularly suited to highest temperature applications above 1600°C (2800°F).

IFB has great features including low thermal conductivity, High heat resistance and durability, excellent resistance to thermal shock, excellent construction strength and structural integrity, etc. IFB can deal with erosive and abrasive environments. IFB can deliver big energy savings for many industries and offer superior structural performance in load bearing applications, even in conditions with mechanical abrasion or severe flow of hot gases.

Typical applications for IFBs include: lining and back lining of various furnaces in the industries of metallurgy, petrochemical, ceramics, machinery, and building materials. 

We have many other types of IFBs, for example:
