Our New Sealed Cast Iron dampers substantially prevent air from escaping the chimney while also preventing outside air from entering the home. This damper utilizes a high temperature fiberglass gasket to form a tight seal, offering energy efficiency for masonry fireplaces without the use of glass doors or chimney top dampers.
