Open windows on opposite sides of your home to let air flow through. This works best when it’s cooler outside than in. If security is a concern, use window latches. In multi-storey homes, open upstairs windows to help hot air escape.
Keep sun-facing windows covered – especially those facing north and west. Light-coloured curtains work best, as they absorb less heat and help keep your home cooler.
Pointing a fan towards an open window may seem backwards, but it helps push warm air out and pull cooler air in, especially if you also open a window on the shady side of your home. This can be more effective than just circulating hot air inside.
A thin plastic film on sunny windows can reduce heat coming in by up to 78%. It also protects furniture from UV damage. Your local hardware store can help you choose the right film, and many options are easy to install yourself.
Trees that lose their leaves during winter provide shade in summer and let sunlight through in winter. Plant them near north- or west-facing walls and windows to reduce heat inside your home. Ask your local garden centre for the best trees for your area.
Investments
We've put together a range of investment solutions to help you ready your home for the impacts of high heat.

Good insulation keeps heat out in summer and warmth in during winter. It slows the movement of heat through your walls and roof, making your home more comfortable year-round. If you’re renovating, check your insulation and consider upgrading.
Double or triple glazing helps control indoor temperature. Some window films or coatings can also reduce how much heat comes through. If you’re replacing windows, ask about frames that insulate well – timber and uPVC are better than standard aluminium. Thermally broken aluminium is a good alternative too.
Screens and shutters block out heat before it enters your home. They’re especially useful on west-facing windows that get strong
afternoon sun.
Eaves, awnings, and pergolas reduce harsh sun while still letting in low winter light. For a natural touch, plant climbing vines or other plants to create dappled shade to cool your home without losing all the sunlight.
Plants, lawns, and permeable surfaces, like gravel or mulch, reflect less heat than concrete or paving. They also help manage water and cool the area around your home. If you’re landscaping, aim for more green cover and fewer hard surfaces where possible.
