Product Description
BNZ Materials PA-26 9 x 4.5 x 2.5" 2600°F Insulating Firebrick - 12ct Box
PN: PA-26
The PA Grade of insulating fire brick (IFB) adds a lower cost alternative to BNZ’s traditional line of IFB. The PA series is designed for applications where the lower density and finer texture of the standard BNZ grades is not required. They meet or exceed the specifications of ASTM C 155 for each listed grade, and are produced under BNZ’s certified ISO 9001 Quality System.
