Positioned against the back wall of the hearth, a fireback protects the masonry of the wall and radiates the heat of the fire forward. By reflecting light and heat from the fire out into the room, a fireback is a noticeable improvement to a hearth. This warmth is gained whether a fireback is used with wood fires or remote controlled gas log units.
A cast iron fireback is still the best way to protect a hearth’s back wall from decay. Despite advances in technology, the harsh rays of fire render even modern refractory materials vulnerable to damage and the likelihood of expensive repairs. A fireback will effectively prevent any further damage to the back wall. If the back wall is already crumbling a firebeack will prevent any further deterioration.
