30″ x 9″ (76cm x 23cm) Oblong Chimney Balloon


This size is suitable for Chimneys that are 25″ – 30″ wide x 7″ – 9″ deep (64 – 76cm x 18 – 23cm


This is a size that can only be found here on the Chimney Balloon website! The 30 x 9 is designed for long, narrow chimney flues. Perfect if your flue is just a little too short and narrow for our standard large balloon. It fits into a range of rectangular chimneys and will help to prevent draughts along with other chimney related issues.

It comes without a mouth inflation tube – if you’ve got an airbed pump or suchlike then you won’t need one. If you haven’t got a pump then you’ll need to add a foot pump or mouth inflation tube to your order.

Having an open chimney is like leaving a window open all the time. Chimneys are designed to draw air from your home, and this happens constantly (even when the fire is out). Around 80 cubic metres of air travels up the chimney per hour (BRE). We all spend money heating our homes, so by letting that warm air escape you’re letting your money escape too! It’s not always noticeable but because the warm air is sucked up the chimney, cold air rushes in to replace the warm air that’s been lost. This causes the draughts we notice from under doors, around windows, and other leaky parts of the building. Keep the warmth in your home and save money – fit a Chimney Balloon.

There are six standard sizes of Chimney Balloon but we found that there was demand for this non-standard size so we’ve added it to our range. If you don’t think this will be quite right for your chimney, and you can’t find the right size in our other range, then get in touch about getting a bespoke one made.
