Why draught proof?
Your house or commercial property will lose heat during cold weather partly due to poor thermal insulation, but also due to the air-leakiness of the building. This warm air loss is technically known as infiltration or permeability and is measured in metres cubed per hour per square metre of floor area. A typical building built 1900 to 1990 will loose around 20-30 metres cubed of air per hour per square meter of floor area. This is due to natural leakage through the fabric of the building, but largely through gaps around windows and doors. Good use of draft proofing could reduce your air permeability to around 8-10 metres cubed per hour which is a good low cost way of reducing you heating bills. The amount of air infiltration to your property will also depend on its exposure to wind so if you are on a hillside or near the coast then it is even more beneficial for you have good draught proofing.
These Chimney draught excluders are designed to be pushed into the narrow part of the chimney above the fireplace, used when the fire is out and the central heating is on.

It has been calculated that for an average sized flue these chimney draught excluders can save you 23 per year off your heating bills for EACH chimney, with the added benefit of reducing draughts within rooms. If you have several chimneys then the savings will be much higher.
