Fire Brick is a refractory brick, used for lining the interior of the fireplace, which is capable of sustaining intense heat without fusion. It is usually made of fire clay or of siliceous material.
Fire Brick differs from common brick in that they are special bricks that withstand extreme temperatures. Because they are also a masonry product, they can also store and control the heat that will be released into the living area of the home. They are placed in a structure where needed and the greatest amount of heat is expected. Fire Brick is not prone to expansion and contraction which helps to minimize cracking under extreme heat conditions.
