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.
