Double Glazed Windows – Double-glazed windows are windows that contain two panes of glass separated by air or a non-toxic gas called Argon.
The gap between glass panels can have a significant impact on the transfer of heat from the outside of your home to the inside and vice versa. And depending on the glass combinations used with your double glazing, it can also have an impact on reducing noise inside and outside your home.
Double Glazed Windows
Now that we’ve covered the basics, let’s take a moment to consider how double-glazed windows can fit your home and your budget.

Jason Windows uses Argon gas because it is more effective than air at preventing heat transfer due to its increased density and reduced thermal conductivity.
Noisy neighborhoods can be a problem. Fortunately, with the right combination of glazing options, Double Glazing helps limit these noisy interruptions by absorbing sound waves to give you a quieter and more comfortable home.
Double glazing also works when the circumstances are reversed – for example, on movie night. With double glazing you can turn up the volume and still be an attentive neighbour.

It is estimated that 40% of a home’s heating energy can be lost and 87% of its heat can be gained through its windows. https://www.yourhome.gov.au/passive-design/glazing. With double glazing, heat regulation becomes easier and more stable.

Because of the temperature regulation that Double Glazing offers, you don’t need to use as much energy to beat the heat or stay warm. And by using less heating and cooling in your home, you can save money on your energy bill. Win, win!
Peter den Boer has worked in the Australian Glass Industry for over 40 years and is respected for his experience and knowledge within the industry. Peter has been the past President of the Glass and Window Society of WA since 2014 before joining in 2018 and had been a board member of the Australian Glass and Glazing Society since 2015. Now a board member of the merged entity – Australian Glass and Window Association. Is your home hot, cold, noisy or electric? If you answered yes to any of these things, then you should turn your attention to double glazing.

Double-glazed windows can help reduce heat transfer through the glass, which keeps your home warmer in the winter and cooler in the summer – and quieter and more energy efficient all year round.
Instead of a single pane of glass, double-glazed windows contain two panes of glass separated by a thin layer of air or gas.

“When you have a temperature difference between inside and outside, you get a heat transfer through the glass,” says Gary Smith of the Australian Window Association.
Double Glazed Window Styles: What You Need To Know
“Whether it’s cold air outside and warm air inside, or vice versa, cold is attracted to warmth. What double glazing does is slow down the transfer of heat.”
Slowing the transfer of heat in and out helps reduce the amount of heat that escapes in the winter and prevents unwanted heat from entering the home in the summer.
This helps to maintain a more comfortable living temperature and reduces dependence on artificial heating and cooling. Which means, of course, lower energy bills.
“Switching from a single glazing to a basic clear double glazing reduces heat transfer by about 50%.
Environmental Impact Of Double Glazed Windows: A Green Perspective
Heat transfer through a window is measured by a ‘U-value’. The lower the U-value, the lower the rate of heat transfer.
Additionally, Gary says double glazing can help reduce some noise frequencies, which can be especially helpful if you live in an apartment or on a busy street.
Wherever you live in Australia, double glazing can help lower your energy bills. It’s traditionally more popular in colder climates, but Gary says it’s also effective in warmer areas.
“When you’re in a hot climate, you also want to reduce the sun coming through the windows because the energy from the sun also creates heat inside,” says Gary.

“You do this with tinted glass products and low e-coating products [which emit low levels of radiant heat] inside the double-glazed unit.”
Meyry Kwik of Magnetite says the company converts single glazing to double glazing by adding a second layer of glass to the inside of existing windows.

“The reason people often choose secondary glazing is that they don’t need to replace their existing windows, which is really useful if you live in a strata unit or heritage unit where you can’t touch your existing windows,” she says. .
What Are Double Paned Or Double Glazed Windows?
This article was originally published on July 9, 2018 at 9:00 am, but is regularly updated to keep the information current. Double-glazed windows are insulated glass units (IGUs). The IGU has several panes in a window system. These are generally double-glazed, i.e. with two panes. A stationary layer of gas or air and a separator separate the panes of glass in these systems. Did you know that all windows must be double glazed?
When double-glazed windows are installed, some of the heat from the glass is lost to the surrounding environment and the windows become cold. When there are windows in a room that does not have winter heating installed, the space will cool even when it is only 10°C. Double-glazed windows help combat this problem because they have multiple layers of insulation. Double-glazed windows keep the heat in. What is heat? In very simple terms, heat is a measure of heat in a material. So, the more heat contained within the material, the warmer it is. If there is not enough heat in a material to maintain a comfortable temperature, this is called thermal degradation. This can lead to sagging in the window frames, or even rotting.
A double-glazed window helps reduce noise by blocking light. This is because windows form a barrier to sound waves. A double-glazed window also helps reduce heat by blocking the heat radiated through it. In some cases, double-glazed windows can help reduce noise by 10 dB. Double-glazed windows block light and heat. Windows are usually 3-8 mm thick and have a heavy or double glazing unit. Double glazing forms a barrier to sound waves and prevents heat radiation. Also, double glazing creates a layer of gas or air to protect the glass from breakage and reduce heat radiation. Double-glazed windows provide sound insulation between the panes. A good double-glazed window will usually have a rating of 90 dB to 110 dB depending on the application.
1. It’s energy inefficient Double-glazed windows are great for blocking out the cold and letting warm air in, but it takes a lot of energy to make IGUs. A double-glazed window will decrease the amount of cooling and heating you use and increase the amount of heating you use. You don’t just think the IGU is heating up, you feel it. Double glazing is also a relatively high energy consumer.
Replacement Double Glazing Windows
2. It costs more. Double glazed windows are expensive. They cost about twice as much as a regular window. This might not be a big deal if you want to spend all your money on other things. If you have a mortgage, a renovation budget or a family to look after, this is something you should consider.
The answer to this question is technically yes, but it may not be the best idea. You can miss out on significant energy savings by replacing a single pane in a double-paned window. The stacks can be damaged during the replacement process, resulting in less efficient windows. Any gas injected between the panes to make them more efficient will escape, again reducing efficiency. t is possible to cause further damage to the sash and the window itself when replacing a single pane of a single window. The replacement process may even get damaged in the process.
Additionally, the amount of work required to do window glass replacement on a double pane is more labor intensive, so it is likely to be more expensive as well.
Depending on the type of heating and the size of the house, it can be difficult to achieve optimal winter heating with natural gas. Windows are the most important factor in heating efficiency and, therefore, fuel use. Glazed windows allow the full effect of sunlight in summer and block it in winter. In addition, insulating a glass window unit is essential. It is recommended that the insulation consists of low-efficiency insulation, which will reduce the heat loss of the glazed window system.
