Keep Out The Cold And Hot Air With A Top Sealing Damper

by | Feb 26, 2015 | Chimney Cap

According to the Chimney Safety Institute of America (CSIA), a damper is a crucial component of every chimney. Necessary for an energy-efficient home, the damper keeps the heat in and the cold air out of your house, which reduces your heating costs. Your damper is also used to control the flow of smoke, gases, and the other byproducts of combustion up the chimney to exit your home. Available in two different types, you can choose between the throat damper and the top-sealing damper. Also known as the traditional fireplace damper, a throat damper is installed right above the firebox and is found in many old masonry chimneys. However, this type of damper has many flaws and issues. At Mr. Smokestack, we strongly recommend the top-sealing damper over the throat damper. We would like to share with you why we feel this way by telling you the advantages of the top-sealing damper over a traditional throat model.

A top-sealing damper serves two functions, allowing you to “kill two birds with one stone.”

One of the main advantages of a top-sealing damper is that it also serves as a chimney cap when the damper is closed, and, frankly, this type of damper actually gives you better protection than an ordinary chimney cap. Equipped with a silicone rubber gasket that seals in heated air during the winter and cooled air during the summer,, a top-sealing damper also gives you an air-tight seal to keep out water, debris, birds, squirrels, and raccoons — just as a chimney cap would. When our customers need a new chimney cap, Mr. Smokestack will recommend that they install a top-sealing damper instead of a chimney cap.

A top-sealing damper will save you both energy and money.

Throat dampers just do not completely seal as well as top-mount dampers, and this fact can cost you a lot of money. You will not have to worry about cold air, ice, and snow entering your flue to create a cold core in your chimney. A cold core tries to cool your home at the same time that your heating system is trying to warm it up, which is a waste of both fuel and money. As a top-sealing damper sits atop your chimney, cold air never even has a chance to get anywhere inside because your entire flue is sealed air-tight with the silicone rubber gasket. Believe us when we say you will save money on both cooling and heating bills when you install a top-sealing damper as it is so much more efficient than the typical throat damper.

A top-sealing damper is easy to operate.

With some throat dampers, you must practically stick your head up the fireplace to open and close them. This is not only very inconvenient, but it can also be very dangerous When you have a top-sealing damper, opening and closing the damper is simple. A stainless steel cable from the damper drops down the chimney and connects to an easily-accessible handle which is mounted inside the firebox. Different models will have different opening and closing methods, but we guarantee you will find all easy to use.
