The home upgrade helping Australians stay warm this winter
And it’s not what you think
Australian homeowners are increasingly treating thermal window furnishings as an energy saving investment rather than simply a styling choice, with new data revealing demand for insulated curtains is growing year on year and starting earlier each season.
Three years of internal sales data from DIYblinds shows demand for its thermal curtain range, including blockout, double and lined curtains, has grown by 44 per cent across the peak cooler seasons between April and September.
The figures suggest Australians are becoming more proactive about improving the energy efficiency of their homes, with many looking to their windows as an affordable way to keep the warmth in and household bills down.
GM Marketing & Online at DIYblinds Liv Tully said Australians are increasingly treating window furnishings as a home performance investment rather than a finishing touch.
"Australians are rethinking what window furnishings are actually for. We're seeing a real move towards double and thermal curtains, not just as a style choice but as a practical response to poorly insulated homes. People are coming to us because they want to feel warmer this winter without a full renovation, and they're planning ahead to do it."
"April sales were 42 per cent higher than they were two years ago. That tells us customers aren't waiting for the first cold snap anymore. They're thinking about comfort and energy costs before winter hits, and they're prepared to invest in it."
July has more than double the demand for thermal curtains since 2023, increasing by 134 per cent by 2025.
The trend doesn't stop when winter ends. September and October consistently emerge as peak buying months as Australians prepare their homes for the summer heat, reinforcing that thermal curtains have become a considered household investment rather than an impulse purchase.
The increasing popularity of DIYblinds' thermal range comes as homeowners search for practical ways to improve comfort without the cost and disruption of major renovations.
According to the Australian Government's Energy Department, windows account for almost 90 per cent of a home's heat gain and can be responsible for up to 40 per cent of heating energy loss. Improving window efficiency can therefore have a significant impact on energy bills.
In Australia, the first insulation requirements came into effect in the 1990’s, and energy has always been accessible, leaving many homes reliant on artificial heating and cooling to maintain temperature in a home.
DIYblinds' thermal range includes thermal backed roller blinds, blockout curtains, lined curtains, double curtain systems and honeycomb blinds, all designed to create an insulating barrier between indoor and outdoor temperatures.
As cost of living pressures continue to affect Australian households, the data paints a clear picture that homeowners are becoming increasingly strategic about how they manage energy use, and thermal window furnishings are emerging as one of the simplest ways to improve both comfort and efficiency.
DIYblinds is currently running its End of Financial Year sale, which falls within the broader winter demand period, giving homeowners an opportunity to upgrade to thermal curtains and blinds while preparing their homes for the colder months.
Until 5 July DIYblinds is offering 20% off custom blinds, curtains and PolyLux shutters for those who are looking to upgrade and keep warm without the hefty price tag.
