If you own an older home, you’re probably no stranger to drafts that come blowing into your living room each winter. Rather than cranking up the heat, a simple device can put an end to the drafts as well as your giant heating bills.

The Chimney Pillow is an air-tight, tear-resistant inflatable bag made from a special laminate. The Chimney Pillow inflates into the gap in your chimey, blocking it off. If you need to use the chimney again, just deflate the pillow and extract it. It’s perfectly safe and shrivels when it is heated.
