What’s not to love about a fireplace and chimney? How about the amount of expensive conditioned air that soars out of it every year? And the amount of cold outdoor air that enters your house through the chimney during the winter? If you have a masonry fireplace, nip those complaints right in the bud with a top-sealing damper.

Details on A Top-Sealing Damper

The top-sealing damper is one of the best innovations to be introduced to the chimney industry. A top-sealing damper will keep energy inside your home and can save you tons of money. National tests actually determined that installing an energy saving damper at the top of a chimney can cut heat loss by over 75%. In addition, these dampers will aid in keeping the elements out. Rain is the chimney’s worst enemy and does real damage to it – so any additional protection is a bonus. Top-sealing dampers also help keep outdoor odors, insects and animals like raccoons, squirrels, birds, and mice out of your chimney.

In the past, most dampers were installed at the “throat” of the chimney, just above the firebox. Because they have a metal-to-metal closure that allows warm air out and cold air in, these internal dampers cannot restrict airflow between the home and the outdoors the way a top-sealing damper can. Most of today’s top-sealing dampers are made of stainless steel and/or cast aluminum and employ a rubber gasket seal that opens and shuts depending on when the chimney is in use. These dampers typically come with a lifetime warranty. By putting the damper at the top of the chimney, you can prevent prevent conditioned air from escaping up your chimney.

Top-sealing dampers should be closed when your chimney is not in use and opened before starting a fire. They open and close like a door and are operated by using a handle located within the home. The damper should be closed once the fire is completely out. It is important to note that top-sealing dampers are only intended for use with a masonry fireplace.
