A top mount chimney damper is a modern, energy-saving solution installed at the top of your chimney flue. It seals off the chimney when not in use and helps control airflow when burning a fire. These dampers are commonly used to replace outdated throat dampers, which are located just above the firebox in traditional masonry chimneys.

Unlike old-fashioned metal-to-metal seals, top-sealing dampers use a silicone rubber gasket, offering a significantly tighter seal. This helps prevent warm or cool air from escaping your home, reducing drafts and cutting down on energy costs.
