What is draught proofing, and why is it important?
Draught proofing means sealing up all the gaps (big and small) where air sneaks in or out of your home—around windows, doors, vents, chimneys, and even curtains. It’s one of the easiest and most effective ways to improve comfort, reduce energy waste, and lower your heating and cooling bills. Generally draught proofing is the first step in you making your home energy efficiency. The major component of a home’s energy costs is used on heating and cooling. Your home can’t be effectively heated or cooled if you can drive a “mac truck” under your front door.
Will this really make a difference to my energy bills?
Yes! Draught proofing reduces how often your heater or air con needs to run. Less hot air escaping in winter, less heat sneaking in during summer = lower energy use, more comfort, and more savings. In the ecoMaster test house, which was draught proofed more than 20+ years ago, we saved 50% of our $2,500 heating bill in the first year after completing it. And of course, we have continued to save that amount every year.
How do I know where the draughts are coming from?
A walk-through your home on a windy day can help you feel where air is leaking in (like under doors or around windows, chimneys and exhaust fans). You can also check unused heating vents, behind curtains, skirting boards, cornices and picture rails —these are often the hidden culprits.
If you’re not sure where to start, you’ve got three great options:
You can try to track down the draughts yourself, or get a little help with our Find and Fix My Draughts program—designed to guide DIYers in spotting every sneaky gap in their home. Prefer to leave it to the pros? We can connect you with a trusted draught proofing technician in your area for a full in-home assessment. Just get in touch and we’ll point you in the right direction.
What products do I actually need?
That depends on where the leaks are!
- Draught Dodgers for effectively sealing doors and windows.
- Chimney Draught Stoppers block open fireplaces.
- Goodbye Heating Vents seal off unused ducted heating.
- DraftStoppas stop airflow through ceiling exhaust fans.
- Invisible Pelmets help block airflow and heat loss behind curtains.
- UltraClear seals gaps and cracks where one surface meets another.
If you’re not sure, start with either work with the online program Find and Fix My Draughts, follow the Draught Proofing Information Hub one room or hire a draught proofing technician. Or contact us for a referral to a trusted draught proofing technician in your area.
Can I install draught proofing myself, or do I need a tradie?
Most draught proofing products are totally DIY-friendly—especially with the help of our video guides. They’re designed for everyday Aussies, not just seasoned professionals (althought they also buy ecoMaster products). If you’re comfortable using basic tools, you can do this. We indicate where any particular product requires an experienced hand.
If you could prefer for a draught proofing assessment and professional installation, please contact us for a referral to a trusted draught proofing technician in your area.
