The sealant on the windows and doors is important, but don’t forget about the fireplace! The combustion process can release a ton of hot air into the flue.
Home fires don't just come from an open fireplace. A blocked throat damper- an iron frame and door that opens and shuts the firebox- in a fireplace can lead to dangerous slow leakage.
A chimney cap is the best way to seal your fireplace. It's also the easiest and least expensive option out there. You can find one on any website or at your local hardware store.
A chimney cap is installed at the top of the chimney and should be spring-loaded for a tight seal. To open it, you should use a steel cable to release the lid.
The chimney cable will hook up to the damper at the top of the fireplace, and all the way down to wherever you store firewood. You may need to replace it after several years if it's used very often.

If the cable disconnects or there is a chimney fire, the candle will remain in its open position.
The right type of cap will keep the rain out, prevent leaks and preserve your chimney. They can also stop pests from entering, like squirrels & birds- no need to worry about downdrafts
We at Spray Foam Insulation Today offer 2 different types of dampers. It's important for your fireplace to stay free of ashes and debris, which is why mesh animal guards are installed to keep animals from getting inside.
Another important feature is chimney caps that shield the apparatus from rain. Stainless steel and cast aluminum are popular fireplaces materials because they're durable and resistant to rusting.
The second unit is aluminum and can be used for round or square flues. Like the first, it has silicon rubber seals that work just as well. The pivoting damper is less prominent and of sight frame of view.
Top sealing dampers are great for wood stove inserts or log fires. We use a round stainless steel flue that threads through the throat damper on the insert/fireplace to do this.
Replace this area of the seal by using fire-proof insulation, which is of course necessary for safety. A more reliable seal can be made by installing a top-seal damper, which is preferable considering the potential gas leak.
