To ensure that you get a Chimney Sheep® chimney draught excluder that works effectively, you’ll need to ensure you get the correct shape and size. To get the right shape and size chimney draught stopper, you’ll need to measure your chimney flue. Don’t worry, it’s pretty simple. You can watch our ‘How to measure’ video or follow our simple step-by-step instructions below. Measuring your chimney can be a bit of a messy job so we recommend you don’t wear your Sunday best!
Find your perfect fit! Input your measurements into the sizing calculator hey presto, it’ll tell you which sized Chimney Sheep® you need. Remember to add the extra extension rods to your order if you need them. The size you need will be a few inches bigger than the dimensions of your flue so it wedges into your flue and stays in place. Any excess felt will squash and fold into the flue to fit and create a nice seal with no gaps.
