Draughts can increase heating and cooling costs by 25%, or $340 per year for an average 4-5 person Albury home. These costs can be reduced by installing draught seals around doors and windows. Internal doors can also have draught seals to minimise heat loss between rooms that are air conditioned or heated with those rooms not in use. This is a cost effective way to save energy and can easily be completed on existing homes.
The other benefit is that it stops windows from rattling!
