"In Europe, double-glazed windows are standard. But in Australia, these
energy-saving windows are remarkably uncommon.
Correctly installed, the effect of double-glazing is remarkable. Instead of a
house losing or gaining huge amounts of heat through its windows, double-glazed
windows help keep the indoor temperature at a consistent temperature – reducing
the need to crank up the air-con or heater.
In hot parts of Australia, these windows would keep out heat. In cold, they
would keep heat in. They also slash outside noise. Houses with double-glazing
can add resale value and even improve occupant health.
Why are they not standard? There are several reasons. But our research in
Victoria found the main one is cost – double-glazing costs much more than a
standard single-glazed window.
Heat loss and gain through windows is responsible for about 1.5% of Australia’s
total energy use. As climate change intensifies, making double-glazing standard
in Australia would cut household energy bills and make life indoors more
pleasant. Other countries are moving to even higher performance triple-glazed
windows. But Australia is stuck."
