2600°F Insulating Fire Brick 9" x 4.5" x 2.5"

30 items left

An economical Lightweight Insulating Brick rated to 2600° 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.
