Fire bricks are designed to withstand extreme temperatures and protect the steel sides of your wood heater from excess temperatures.
Although more durable to a normal brick, the fire bricks within your wood fire will eventually break down over time and require replacing periodically. If you notice large cracks resulting in your brick being in a number of pieces - it is time to replace it.
Fire Bricks are also known as: Combustion Heater Bricks and Refractory Bricks.
