1 Upgrade insulation As Guy Manthel of Knauf Insulation explains, when a home is well insulated, heat is prevented from escaping through the walls, roof and other surfaces. “So less energy is required to maintain a comfortable indoor temperature,” he says (see table, below). Not sure whether your insulation needs updating? Firstly, consider that older homes may not have any insulation at all! Secondly, look at your energy bills. “Consistently high bills could be a sign that your insulation – if you have it – is no longer performing effectively,” says Guy. “If it is no longer doing its job, your heating and cooling systems will have to work harder to maintain a comfortable indoor temperature, which can drive up your energy bills.” An uneven temperature is another clue – having some rooms significantly cooler than others can signal poorly installed or ineffective insulation. Updating your insulation may be an achievable DIY job, particularly in the ceiling (see Watch it!, next page). “When retrofitting ceiling insulation, it’s important to choose a product with a suitable R-value – a measure of insulation’s resistance to heat flow – for the specific location, and ensure it is installed correctly,” advises Guy. Unless you’re doing an extensive reno, retrofitting wall insulation can be complex. If you have access to the ceiling and underfloor, Guy suggests insulating these first, using the highest R-value possible for the ceiling to help compensate for uninsulated areas.

To find the most likely culprits, close all windows and doors, turn off appliances that might create a breeze, then light a candle and – very carefully! – hold it near the window and door frames, running it up and down, watching for a flicker in the flame. The most common draughts can be simply fixed with a few cheap DIY tools. Using a caulking gun and gap filler, you can quickly fill cracks between the walls and window or door frames, and even between timber floorboards. Adhesive weather seal tape can be applied around window and door frames, where the wind often whistles in. Seal the bottom of exterior doors by installing a door sweep or utilising an old-fashioned door snake. bunnings.com.au | bunnings | bunnings | bunnings 35
