Glass Fireplace Doors are more than great looking. Glass fireplace doors act as a warm air barrier, keeping your furnace heated warm room air in your home.
Even with your damper closed, your standard fireplace constantly siphons warm room air up the flue and out of your chimney top. The amount of heated air loss can be astounding, which also increases your energy bills.
How do quality glass doors stop air loss?
The science of fluid dynamics are at work. Put simply, passive air is prevented because quality glass doors do not let air pass through the gaps between panes of safety glass and small gaps (about 1/8” or less) between the glass and the frame.
Your heated room air stays where it belongs, in your home (not out the chimney), your energy bills don’t increase and your fireplace will look better than ever!
