Chimneys: Draft Stopper

Whether or not your fireplace flue is open, there's may be heat going up the chimney. The Fireplace Draft Stopper is designed to be inserted into the fireplace's flue and inflated (using breath power), creating a seal against heat loss.

Two sizes (round and square) are designed to fit masonry (traditional brick) fireplaces or round (for prefab fireplaces). Before installing it, you'll want to check the fireplace opening for sharp projections that could puncture the inflatable device.
