Draught-proof gaps, windows, doors and vents to save money on energy costs.
Even if your home is well-insulated, heated or cooled air can leak in and out through gaps and cracks.
Draught-proofing your home is one of the easiest and cheapest ways to lower energy costs.
Yearly saving on energy up to $120.
Save up to 240kg of CO2 per year (average family).
Put draught stoppers at the base of doors to help keep warm air in during winter and cool air from escaping in summer.
Energy saving data from Tony Isaacs thermal model using Melbourne climate and pre-1990 130m2 house with gas ducted heating. Improvement cost assumes no draught sealing in place initially and spending over 6 rooms for tape, foam, external doors excluders and sealer.
Select self-closing models (automatic shutters or dampers) to stop air leaks, and always vent exhaust fans and rangehoods to the outside, not into the roof space or wall cavity.
For existing fans, fit a lid over the outlet. The lid blows open when the fan is switched on and falls shut when the fan stops. Products are also available to seal non self-sealing exhaust fans.
