Chimney Fireplace Dampers
An old throat damper leaks conditioned air straight up the flue. A modern top-sealing chimney damper mounts at the top of the flue and creates an airtight seal, cutting energy loss dramatically compared to a traditional metal-on-metal throat damper. Choose from lock-top, Lock Top II, and Lyemance designs to match your chimney and flue shape.
