Chimney Draught Excluders

When it comes to draught-proofing chimneys, you can’t get better than a Chimney Sheep® chimney draught excluder. As the best chimney draught excluder on the market and the only one with industry reassurance via the BBA , a Chimney Sheep® chimney draught stopper will ensure your home is kept draught-free. Our open fire draught excluders stop around 5% of household heat from escaping, reducing energy bills for the average household by £99 per year as well as helping to reduce wind noise down your chimney.  

A Chimney Sheep® is a sheep wool chimney draught excluder made of Herdwick Sheep’s wool which we source from our local farmers in Cumbria. The device lodges into the throat of an open fireplace stopping warm air from your home escaping and keeping the outside cold air out. Unlike a chimney balloon draught excluder which leaves a small vent in the side for airflow, the wool used to make a Chimney Sheep® is naturally breathable allowing for more efficient ventilation whilst still being effective at keeping draughts at bay. A Chimney Sheep® can be used as a draught excluder in open fireplaces and can also be used as a chimney draught excluder for gas fires that have been decommissioned as advised by Gas Safe.  

There is no such thing as a universal chimney draught excluder (despite what you might have seen) as each chimney is different in shape and size, which is why our range of wool chimney draught excluders come in a range of dimensions. To ensure you get the correct sized fireplace draught excluder, head over to our instructions on how to measure your chimney. Once you’ve measured your chimney you can use our size guide to choose the correct size. We have tried to keep our sizing as simple as possible but chimneys vary in size hugely. If your chimney is too big or won’t fit our standard size of chimney draught blockers, don’t panic! Get in touch with your chimney measurements and we can give you a quote for a custom-made Chimney Sheep®.
