33″ x 12″ (84cm x 30cm) Oblong Chimney Balloon


This size is suitable for Chimneys that are 33″ – 36″ wide x 10″ – 13″ deep (84 – 92cm x 25 – 33cm)


This size is designed specifically for larger flues: our 33 x 12 rectangular balloon fits into a variety of oblong chimneys.  Perfect if you’re worried our standard large balloon will be a little too big – the 33 x 12 will provide you with that perfect seal! 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 one then you’ll need to add a pump or mouth inflation tube to your order.

The Chimney Balloon is completely original and was the first chimney draught excluder on the market. There have been copies made however they do not take into account the subtle design features that the Chimney Balloon has, for example the venting system to allow your chimney to breathe and material that is strong and safe.

Each part of the Chimney Balloon was carefully designed to ensure it is completely fit for purpose, the material is an incredibly strong consumer safe plastic, that if accidentally exposed to excess heat will shrivel. Other inflatable chimney blockers on the market are made of PVC with is dangerous if accidentally set on fire.

The venting system in the Chimney Balloon has been carefully designed to allow for up to 13% of the air to still flow – an unnoticeable amount, but this helps to prevent damp in chimneys.

As you can see the Chimney Balloon is the Original and Best Chimney Draught excluder!
