Guide to Fireplace Mantels Mantels are an ornamental facing or a protruding shelf around a fireplace. Finely crafted mantles can turn direct vent or ventless fireplaces into attractive centerpieces. Mantels frame a fireplace and can be used to collect and display fireside decoration. Initially fireplace mantels were constructed primarily of high-density fiberboard and wood moldings. However, they are now constructed of various types of wood, marble or stone, porcelain or metal accents like gold or silver that add a nice touch of elegance. Most mantels are usually 10 to 20" deep and have the capacity to bear all the heat emanating from the fireplace. They bring life to the room and provide the perfect place to display some of the prized collectibles.
