Use Chimney Balloons and Get Better Output than Metal Dampers and Glass Doors

The Chimney Balloon fireplace chimney damper is made of a heat reactive material. It is designed to safely deflate within seconds and allow the smoke and gases to exit your chimney if it is exposed to heat or flame. The chimney pillow is made of a specially engineered 3-ply poly membrane. You can easily install this inflatable chimney damper by holding it in place in the chimney while you inflate it with air through the detachable inflation hose. It can be re installed and can be re used many times.
