The Chimney Balloon was created by engineer and inventor David Woodman in the late 1980’s. He and his wife Irene developed the Chimney Balloon Co, and back in the days when there was no internet, grew it into an international business. When the patent expired in 2012 there was a flurry of cheap copies that appeared on the market. These were made by attempting to reverse engineer the Chimney Balloon but failed to appreciate some of the finer details. The Chimney Balloon remains the most effective and safest of the inflatable chimney draught excluders.
The Chimney Balloon Co was sold in 2017 to Chimney Sheep Ltd. There is a synergy between the two types of chimney draught excluder and the friendly team are happy to advise on which product is suitable for your chimney.
The Chimney Balloon is made by Watford Workshop, a charity which gives work experience, skills training and employment for disabled and disadvantaged people. You’d be surprised by how complicated it is to make the Chimney Balloon and each stage requires careful scrutiny to ensure the product doesn’t have any weak points. Watford Workshop have made over a million Chimney Balloons and there have only been 4 failed products in that time: testament to their skill and attention to detail.
The Chimney Balloon has been tested by BSRIA and was found to block 87% of airflow up the chimney. The Buildings Research Establishment state that 80 cubic metres of air travel up the chimney per hour so fitting a Chimney Balloon is one of the quickest and cost effective means of draught proofing your home.
