2500°F IFB Insulating Fire Bricks - 9" x 4.5" x 2.5"

Quality Lightweight IFB (Insulated Fire Bricks) 9" x 4.5" x 2.5" thick. Rated to 2500° F Fahrenheit that can be installed in either a backing or a hot-fired application. Easy to cut. If you need a higher temperature-rated insulating brick, see our 2800°F Insulating brick. The low iron content is also suitable for reducing and high CO environments.

These bricks are much more porous, and not as mechanically strong as our high-density bricks. However, they can be stacked dry or set using SAIRSET refractory mortar.  Though they have much less of a heat sink than denser bricks, these can still be coated with ITC 100 HT and benefit from the added efficiency of ITC 100's heat reflection properties.

**also available with ITC-100 reflective coating one side (furnace baked).
