Chimneys and fireplaces experience a lot of wear and tear over the course of a burn season. The constant, rapid heating and cooling from the inside and the rain, sleet, snow, ice, and wind that batters the exterior of the chimney can cause lots of problems! One part of the system that is particularly susceptible to damage is the chimney damper. Traditional chimney dampers were composed of metal and located in the throat of the system. As a result, they often rusted into place and didn’t provide an airtight seal. Nowadays, top-sealing dampers are commonly used – these dampers typically do a better job of sealing off the chimney than their ancestors.
Having a top-sealing chimney damper installed is one of the best ways to cut down on heat loss and energy costs in your home, while simultaneously keeping animals, water, and debris out of your chimney. A top-sealing damper closes at the top of the chimney instead of in the throat. Instead of metal-on-metal contact, these dampers use a rubber gasket to create an airtight seal, keeping the warm air in your home and the cool air out. This can decrease heat loss by up to 75%! In addition to keeping in conditioned air, it also keeps water, debris, and animals out!
A top-sealing damper is operated with a handle inside the firebox. Before starting a fire, you must open the damper to allow the smoke and dangerous gases an avenue of escape from your chimney — otherwise, they would build up in your home and cause major problems. After enjoying your fire, simply close the damper. The airtight seal will help ensure that no conditioned air is lost, no water enters your chimney flue, and no animals or debris make their way inside.
