But these cheap and innovative tricks can make a big difference.<\/p>\n
Hunt down and block draughts<\/p>\n
Heating expert Chris Barnes, from consumer group Choice, says air leakage from under doors and around windows is a big problem in many Australian homes.<\/p>\n
Based on Gadigal land in Sydney, Mr Barnes says a simple way to find the source of draughts is to walk around your home with a lit incense stick.<\/p>\n

And then you know where to target with door snakes,” he says.<\/p>\n Door snakes are long fabric tubes, often filled with sand, that sit along the base of a door to block cold air, and prices range from $4\u201320.<\/p>\n Jenny Edwards is a scientist working to create energy-efficient and cost-effective homes in Canberra\/Ngunnawal country.<\/p>\n Ms Edwards says door snakes are easy to pick up from the op shop and instantly solve “obvious leaks under your doors”.<\/p>\n For drafts around windows, Mr Barnes says weather strips, “which are just sort of rubber seals”, are extremely effective for window gaps.<\/p>\n They can be bought at hardware stores and typically cost $6\u201320.<\/p>\n Thermal cameras can help you find the cold spots in your home. (ABC\/Fremantle Media)<\/p>\n Hire or borrow a thermal camera<\/p>\n If you’re still feeling chilly after trying the incense trick, it’s worth investigating where the cold spots are in your home, as they may be where you’re losing heat.<\/p>\n “A lot of councils, through their local library networks, offer thermal cameras as a rental, or maybe just as a free service to ratepayers,” Mr Barnes says.<\/p>\n “A thermal camera can really help you sort out where the issues are in your house \u2026 looking for the hot spots or the cold spots.”<\/p>\n Like gaps in your ceiling insulation, he says, as an example.<\/p>\n “But you can use them all over the place, obviously.”<\/p>\n Place rugs on floorboards<\/p>\n One place a thermal camera may find cold spots is the floor.<\/p>\n “If you’ve got bare floors, rolling out rugs in winter does make a difference,” Mr Barnes says.<\/p>\n Rugs can help plug draughts from gaps in floor boards and add an extra layer of insulation to your room.

(ABC News: Lily Nothling)<\/p>\n Ms Edwards says most homes have curtains or roller blinds, but many don’t have pelmets, which are frameworks placed above a window (often associated with traditional-looking curtains) that can help prevent heat loss.<\/p>\n Warm air naturally rises, but when it “cools down, it drops across the face of the window creating a nasty draught”, which the pelmet stops, she says.<\/p>\n Ms Edwards says you can use a scarf or a piece of fabric to do the same job.<\/p>\n “After you close your curtains at night, lay that across the top of the curtain to create your own pelmet,” she says.<\/p>\n “You can also often create a pelmet out of cardboard, depending on the type of curtain rail.”<\/p>\n Lining your windows with bubble wrap puts a buffer layer of air between you and the cold outside. (ABC News)<\/p>\n Bubble wrap ‘double glazing’<\/p>\n Mr Barnes says while it can be unsightly, bubble wrap is another way to prevent heat loss and insulate your home.<\/p>\n![\"A](\"https:\/\/www.europesays.com\/australia\/wp-content\/uploads\/2026\/07\/cfc0c3385b027d095424e6e2880f3909.jpeg\")
