What are firebricks?

Firebricks are found in the firebox of a stove and protect the insides of the stove from the intense heat of the fire. Modern firebricks are often made from vermiculite a light highly insulating material that not only protects the inside of the stove but also increases the temperature in the firebox thus increasing efficiency.

Many boiler stoves have a wraparound boiler which forms the back and sides of the firebox so firebricks are often unnecessary in these boiler stoves.
In boiler stoves with clip in boilers the boiler replaces the firebricks at the back of the stove and the firebricks at the sides remain in place.
