A fireplace glass door is installed on a fireplace to keep the room warm longer when the flames die down. Whether a wood burning fireplace or a gas burning fireplace, heat radiated into the room escapes through the chimney. One does not notice this while the fire is burning brightly, because of the heat from the flames that radiates into the room. However, when the fire starts to die down, the hearth becomes cold quickly as the heat escapes through the fireplace opening. To stop this from happening, a fireplace glass doors blocks the opening, keeping the warm air from leaving the room.
All of the items above are usually made from steel, brass, bronze and, less commonly, iron. Requirements for special heat resistance are low as no one would ever keep a poker in a burning flame. All the tools are just a part of the interior and mostly perform aesthetic and artistic function. The choice of subjects and manufacturers depends on the owner's willing to arrange an elegant fireplace area.
