A Chimney Sheep® is a highly efficient, removable chimney draught excluder made from felted Herdwick sheep’s wool. Our original and best-selling product ensures your home is heated efficiently by keeping the heat in and the cold draughts out.
We think a Chimney Sheep® is a no brainer! Why? Here are a few reasons:
This Chimney Sheep is suitable for chimneys 8″ – 12″ x 8″ – 12″ (200 – 300mm x 200 – 300m). This is a versatile size with an extra row of stitching so it can be trimmed to fit if necessary with a pair of sharp scissors. If you’re not sure what size to get have a look at the sizing chart.

A Chimney Sheep® draught excluder is made from highly durable and naturally breathable Herdwick wool, from a Herdwick sheep. The wool is treated with a unique ionic protect plasma which makes it 100% moth proof and aids with the longevity of the Chimney Sheep® (we have customers that have had the same ones for nearly 10 years!). It is then felted to create a unique flexible yet sturdy material. This makes the Chimney Sheep® perfect to plug the gap just above a fireplace.
The woollen pad of the Chimney Sheep® compresses to fit perfectly flues of all shapes and sizes making it far more efficient than any other chimney draught excluder on the market. Inflatable chimney blockers and chimney umbrellas require a small gap to be left in your flue to allow ventilation but because wool is naturally breathable, a Chimney Sheep® doesn’t require that gap. Instead, once inserted into your chimney flue the 4.43 tog rated Chimney Sheep® acts like a duvet, blocking 95% airflow into and out of your chimney, whilst naturally permitting sufficient ventilation. It works to prevent warm air from escaping up the chimney and stopping cold air from coming in via the chimney when not in use, reducing the ‘stack effect’ phenomenon.
It is as simple as that! Read more about the stack effect and how a Chimney Sheep® works here.
The list is endless but here are a few of the main benefits:
It really does! Don’t take our word for it, here is all the evidence:
Absolutely. We are really passionate about the environment and sustainability. Everything from our sourcing of wool to our packaging is chosen with the environment in mind and the aim of our reducing our carbon footprint as much as we can.
All Chimney Sheep® are made here in our factory in Maryport, Cumbria, using Herdwick wool sustainably sourced from farmers around Cumbria. We collect the wool once a year which we call our ‘Operation Wool’ project. We pay the local farmers a fair price for this which is usually more than the market price and helps to support them.
The felt head of a Chimney Sheep® usually lasts about 10 years and is 100% wool which means it is completely biodegradable and compostable. The handles are made with recyclable plastic therefore are extremely durable and designed to last for decades. We have designed them so that when the felt head does wear out, you can just replace it with a new felt head and keep the same handle to reduce waste and the use of excess plastic. When the time comes and you have to say goodbye to your felt head, get in touch with us.
By using a Chimney Sheep® you are doing your bit to reduce your carbon footprint and we are really passionate about helping you to reduce your CO2 output even further. That is why we have set up our very own Community Interest Company, Buy Land Plant Trees, so that with each purchase a proportion of the profits will go towards planting trees on agriculturally poor land.

All you need to do is measure your chimney. We promise, it sounds more complicated than it really is! Head over to our simple instructions which walk you through it. If you do have any trouble though, just get in touch and we can help.
Our standard Chimney Sheep sizes will fit the majority of chimney flues. However, each and every chimney (like us!) is unique so if your chimney doesn’t look like it will fit one of our standard sizes, contact us with the measurements and we will give you a quote for a made-to-measure Chimney Sheep® that will fit your chimney perfectly.
