WGD Chimney Sheep® Chimney Draught Excluders

How does a Chimney Sheep® draught excluder work? 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 over 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!
