Firebricks
 |
Often used in furnaces, these firebricks have been machined for a snug fit to minimize heat loss. They are flame resistant, meeting ASTM E84 0/0 for flame and smoke. Cut with a brick saw and install with the firebrick bonding mortar (sold separately).

Abrasion-Resistant Firebricks
|
Stronger than standard firebricks but with lower insulation capabilities, these withstand heavy abrasion on the floors and sides of furnaces. They meet ASTM standards for flame resistance. Also known as hard firebricks. Cut with a diamond-tipped tile saw and install with firebrick bonding mortar (sold separately).
