Fitting a Chimney Balloon to an open chimney is like fitting the gap with double glazing. The Chimney Balloon is designed to inflate and push against all four walls of the chimney, holding itself firmly in place. There is a small vent in the side of the product which allows some airflow, permitting your chimney to “breathe”.

The rubber bands hold the top and bottom together, enabling it to push outwards as it’s inflated. Being stretchy, they allow far greater range of flex than some other inflatable chimney draught excluders with inflexible central cores. This means each size will fit a greater range of chimneys.

Being effectively a double barrier with the top and bottom of the balloon, air is trapped inside, insulating the chimney against cold air sinking down, while simultaneously preventing warm air from rising up.

The balloon also insulates against sound, prevents debris and wildlife from falling in, and reduces weather ingress.

I purchased a chimney balloon from a few weeks ago. It arrived in record time. I had set up a giant jixsaw to do over christmas right in front of the fireplace, and prior to installing the chimney balloon, I was subjected to a strong draught which was coming down the chimney. Since installation, I have experienced no draught! The chimney balloon has made a huge difference to sitting room. It is cheaper to heat and there is no noise from the chimney.

I am delighted to have come across, finding the website and service very efficient and any staff I’ve had the pleasure to deal with most curteous and friendly

Chimney Balloon Spare Tap



  1. I hate to be devil’s advocate here, but I’d like to know when and where the first chimney fire related to these devices occurs. Naturally somone will forget such a device is in place and light a fire. Don’t these fireplaces have dampers? There’s a quick and easy diagnosis if you forget to open the damper when starting a fire as your entire home will fill with smoke. Oops! How do you explain to your home insurance company the cause of the fire was a plastic balloon that you voluntarily stuffed up the pipe, and will they pay out for the damages?

    1. David firstly I would like to say that this product is on the market since the 1990s and we have sold thousands of units ourselves over the past 6 years we are in business so it isn’t something new. It has been tried and tested and is designed for chimneys which are never or rarely used only.
      Secondly it comes with a red label which says “remember to remove the chimney balloon” and it is suggested to customers to place this label in the fireplace to highlight the fact that it is installed. We also suggest that the inflation tube that comes with the chimney balloon is not removed after it is installed and instead hangs into the fireplace and is thus clearly visible.
      Finally if you do light a fire the chimney balloon will simply shrivel up and fall into the fireplace. We have spoken to many people in the past that wished that they had bought a chimney balloon rather that stuffing there unused chimney flue with old pillows and cushions. If you were to light a fire in this situation it would cause far more damage.

  2. Hi
    Can I ask what length is the inflation tube as it would have to be at least 24 inches
    For me to able to inflate it in position
    Thanks Martin
