WHAT IS DOUBLE GLAZING?
Double glazing windows and doors have two glass panes bonded together by a spacer and separated by a gap of at least 6mm.
The gap is hermetically sealed and filled with argon to provide an added layer of insulation. Ideally, double glazed windows and doors should use toned or low-E glass to improve their performance.
Structurally, the gap between these separated panes is the critical difference between double-glazed and single-glazed windows and doors. Yet, the real difference lies in the unique benefits of double glazing.
SUITABLE FOR HOT AND COLD CLIMATES
Double-glazed windows and doors are popular in colder climates such as Victoria and Tasmania.
Still, many people don’t realise they are an incredibly energy-efficient solution for all Australian climates.
While some energy-efficient products can only reduce heat loss or gain—or both—inefficiently, quality double glazing is different.
Its unique insulation properties keep the home cooler in summer and warmer in winter by limiting the hot or cold airflow between the two panes. Not only does this make the home comfortable year-round, but it also helps minimise reliance on artificial heating and cooling.
REDUCE HEAT LOSS AND GAIN
Windows and glass doors play a crucial role in your home’s energy efficiency.
It’s estimated that almost half of all heat loss during winter and nearly 90% of heat gain during summer can come from windows and doors.
The unique design of double-glazed products insulates against heat and cold up to four times more effectively than single-glazed windows and doors.
The space between the two panes of glass acts as a thermal barrier between your home and the outside environment. It prevents warm or cool air from escaping, maintaining a steadier temperature and insulating you from the effects of climatic extremes.
LOWER POWER BILLS
Energy costs have climbed by over 50% in Australia over the last decade – with half the energy used in Australian homes powering heating and cooling devices, keeping cool in summer and warm in winter is more unaffordable than ever.
Australians pay the highest energy prices in the world, two to three times more than American households.
The good news is that installing double-glazed windows and doors is one of the most effective ways to make a home more energy-efficient.
Double gazing is such an effective insulator that it can reduce your need for electrical temperature control. This design feature can decrease your power bills by more than 20% compared to single-glazed windows, while also helping the environment.

DOES DOUBLE GLAZING REDUCE NOISE?
Double glazing can reduce outside noise—from voices, animals, vehicles, planes, trains, and other sources—by up to 60% compared to single glazing.
The World Health Organization has found that exposure to prolonged noise can contribute to stress, sleep and cognitive problems, and health conditions such as cardiovascular disease.
Double-glazed products absorb more sound energy than standard single-glazed products due to the gap between the glass panes. Adding acoustic glass increases the effectiveness of double glazing.

Condensation occurs when the moist air inside your home is exposed to a cooler surface’ such as a single glazed window.
While condensation is generally just an annoyance, it does have the potential to cause severe problems for your home.
Double glazing products reduce the likelihood of condensation by removing its key cause – a cold window. The interior glass pane stays close to room temperature, reducing your condensation risk.
DOUBLE GLAZING VS SINGLE GLAZING
As you can see, there are several benefits to choosing double-glazed windows and doors for your home.
