Draught proofing is one of the easiest DIYs one can do to fix your home of draughts and leaks, making your home more comfortable and energy efficient. Draughts are similar to ventilation, in that both let fresh air into your home. Good ventilation helps reduce condensation and damp and can help cool down a hot house. Draughts, on the other hand, are uncontrolled – they let too much cold air in and waste too much heat.
Draught proofing stops warm air from escaping your home in winter and hot air from entering in summer, saving you money and making your home more comfortable. Up to 25% of winter heat loss from existing houses is caused by air leakage (also known as draughts). In fact 9 out of 10 homes in Victoria have unwanted draughts!
Draughts come into your house through gaps and cracks around doors, windows, exhaust fans, fireplaces and so on. To draught-proof your home you will firstly need to find the draughts.
- Look for obvious gaps
Visible light under and around doors and windows is a good clue.
- Listen for rattles or whistling
Take time out, especially during strong winds, to listen for rattles and whistling around doors and windows.
- Feel for moving air
Feel around doors, windows, fireplaces, air outlets, vents, stairways, floorboards, exposed rafters and beams, built-in heaters and air conditioners, architraves and skirting boards.
- Look for movement in curtains
Movement in and around curtains can be an indicator of draughts.
