Chimney top damper reviews.
The damper closes all the way but due to it s design a very small amount of force can break the seal.
Mounts on top of your chimney to keep out animals leafs bugs snow and rain easily operates from inside your firebox and seals tight every time you close it eliminating any draft.
Only issue with ours is sometimes it closes all the way and sometimes it only closes about 3 4 of the way.
It immediately stopped the draft through the chimney in my house.
Top dampers are cheaper and easier to have repaired or replaced if need be as well.

The top sealing chimney damper is designed to stop cold air from coming down the flue and expensive conditioned air from going up.
Lymance top sealing dampers are as much as 90 more efficient than throat dampers because they provide a silicone rubber gasket seal rather than metal to metal seal.
Usually the default position for these dampers is open which means that if there is a problem with the damper s operation cord the damper will be stuck open.

3 0 out of 5 stars does enough for the job.
I think top sealing dampers are a great investment and energy savers and as a side benefit they preheat the stem of the chimney from the bottom to the top with warm air often allowing a much better up flow draft of the fireplace smoke.
It seems the cable sometimes interferes and only closes 3 4 of the way.
Lock top top sealing dampers are as much as 90 more efficient than throat dampers because they provide a silicone rubber gasket seal rather than metal to metal.
Pretty easy to install.
Unlike the top mounted damper which is obviously located on the upper end of the chimney the throat damper is located more towards the fireplace.
