An open fireplace is basically a hole in your roof. The amount of heat which is lost represents a huge waste of energy and money. If you don't want to give up your open fireplace, consider fitting it with a set of glass doors. You will reduce the loss of heated room air while still enjoying the dancing flames. Before you visit us, measure your fireplace height and width. If the opening is irregular, such as stone, a custom glass enclosure will likely be needed. We have some high quality doors from Diamond W and Portland Willamette in dozens of finishes and many styles. Be prepared to spend $600 for a basic set of doors, and $1500 or more for custom doors.
