RI 23 High melting point; used for glass furnace insulation as well as general furnace usage.

RI 23 B is a higher cold crush strength version of RI 23. Used for anode baking furnaces worldwide.

 
 

Calor A is the traditional Grade 25 IFB for furnace and kiln applications.

Calor B is a stronger, denser version of the Calor A.

Calor CA is a high strength version of Calor A, used extensively for aluminum reduction cells worldwide with proven resistance to aluminum, metal and
 

associated process fluorides. Also used for general insulation as a high cold crush strength 25 grade insulation.

Calor 26 and 26 B are general purpose 26 grade insulations, suitable for anode baking furnaces and glass melting tank insulation.
