Re: Cold air from fireplace despite 2 dampers
You have to remember that you have a rather sizable masonry mass sticking above the roof, it gets cold and cools the air in the chimney, the cold air falls and comes out the fireplace. Fire place dampers are notorious for leaking. Even if they don't when new a few fires and they start to warp and not fit as they should. Blocking the fireplace opening will help. A good set of glass fireplace doors properly installed will come as close to accomplishing that as possible.
