The Chimney Sheep® is the best of all chimney draught excluders and will ensure your home is kept draught-free! You’ll need the dimensions of your chimney in order to select the correct Chimney Sheep® chimney draught excluder. Instructions on how to measure your chimney can be found here. 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 sizes, don’t panic! Get in touch with your chimney measurements and we can give you a quote for a custom-made Chimney Sheep®.
