A flue is a duct, pipe, or opening in a chimney for conveying exhaust gases from a fireplace, furnace, water heater, boiler, or generator to the outdoors.
Chimney Dampers. Chimney dampers allow you to close the chimney flue when the fireplace is not in use to prevent heated or cooled air from escaping the home through the chimney. An open flue is an invitation for inefficient climate control and added problems due to prolonged exposure of the chimney to the elements. Using our large inventory of chimney dampers, you can make sure that you get the most out of your chimney and your home year round.
