The Top-Sealing Damper — An Energy Saving Replacement For Your Rusty Fireplace Damper

What do you want to keep out of your chimney?

  • Rain
  • Snow
  • Sleet
  • Ice
  • Animals
  • Birds
  • Debris

What do you want to keep inside your home? The air you’ve spent money heating so you can maintain a comfortable living environment.

What if you could do all that and replace a rusty, broken, or difficult-to-open/close fireplace damper at the same time? With a top-sealing damper from Olympia Chimney Supply or National Chimney Supply, you can.

What Are Traditional Fireplace Dampers?

First, let’s talk a little bit about traditional fireplace dampers or throat dampers and why they sometimes fail. Traditional fireplace dampers are metal plates located down in the throat of the fireplace system, just above the smoke chamber and below the flue.

When opened, the damper allows smoke and any other byproduct of combustion to freely flow up into the chimney and out of the home. When closed, the damper prevents smoke from exiting and blocks the flue to keeps animals, birds, and other critters from coming down into your fireplace. You could imagine the damper is like a bouncer, deciding who gets in and who gets out.

But because the damper is right in the middle of all the action, it can get pretty beat up over time. Moisture from the fire and from a leaky chimney can cause the damper to rust, and once rusted, the damper will be difficult to open and close. Likewise, these dampers can break over time because of their placement and the abuse of the fire.

Of course, that’s not the only problem with a traditional fireplace damper. As metal plates with only metal parts, there’s no way for the fireplace damper to prevent cold outside air from coming in through your fireplace or cozy, heated air from leaving through your fireplace. In other words, they’re not energy efficient, they make it difficult to maintain a comfortable living space, and they can lead to a lot of energy waste and money waste.

Top Sealing Dampers

How Are Top-Sealing Dampers Different?

So now, how are top-sealing dampers different?

Firstly, top-sealing dampers aren’t located down in the throat of the chimney and fireplace system. Instead, they’re installed up at the top of the flue, providing protection against things like moisture, animals, birds, and downdrafts.

Secondly, top-sealing dampers have rubberized gaskets, so they provide an airtight seal when closed. That means you won’t be losing any of your home’s heated air up through the chimney.

In other words, top-sealing dampers provide extra protection to your flue and fireplace, prevent leaks and animal/bird entry, and help you save money on utilities, while maintaining a more comfortable home.

An added bonus is that these dampers help keep the flue warmer so that when you do go to light a fire in your fireplace, the fire is easier to start, and you get more heat from the fire, and better performance from your fireplace system. And with the easy-to-operate drop-down handle, it’s easy to open and close these dampers, even though they’re located further up the chimney system.
