Chimney Sheep® draught excluder

Having an open chimney is like leaving a window open all the time. Close it off with a Chimney Sheep®, the most effective chimney plug.

What is a Chimney Sheep®?

A Chimney Sheep® is a removable chimney draught excluder made from highly durable, naturally breathable Herdwick wool. The wool is felted to create a perfect plug for the chimney and a handle added for easy insertion and removal. A Chimney Sheep® makes your home feel more comfortable by stopping warm air escaping and preventing cold air from coming in, whilst providing sufficient ventilation to prevent damp issues occurring. Installing a Chimney Sheep will make your home feel warmer, reduce wind noise, heating bills, CO2 emissions and prevent any debris fall down from the chimney into your hearth.

Small Range

Our range of small Chimney Sheep® draught excluders are for small chimneys. All our round-shaped chimney draught stoppers form part of this range as well as our smallest oblong Chimney Sheep®. If you measure your chimney and there isn’t a size small enough, get in touch for a bespoke Chimney Sheep® quote. Please ensure that if you're using a Chimney Sheep® chimney plug in a gas fireplace, it has been decommissioned as advised by Gas Safe or use one of our magnetic fireplace draught excluder blankets.
