Chimney balloons are a very effective way of blocking unwanted chimneys.

The Chimney Balloon is made from special, durable, long-life plastics.  Simply inflate it to block the chimney cavity.  Stops chimney downdraughts and updraughts. Stops debris, soot and bird mess.  Inflate to install, deflate to remove.  Allows a little ventilation.

Use again and again each year.

Saves heating costs.
