Windows are key to determining the energy efficiency, comfort, and aesthetics of a home or commercial space.
But how do you know which type of window is best for your needs?
At O’Brien Glass®, we pride ourselves on providing quality glazing solutions to everyday Australians, so we’re going to walk you through the differences between the two primary types of windows – single-glazed windows and double-glazed windows, to help you make an informed choice.
What is the difference between double-glazed and single-glazed windows?
Single-glazed windows consist of a single pane of glass. They are the most basic and traditional form of window glazing. While they are popular because they are cheaper upfront and easier to install, they offer less thermal insulation and soundproofing than the double-glazed alternative.
On the other hand, double-glazed windows or units (or ‘DGU’ when speaking in glazing lingo) consist of two pieces of glass separated by a spacer bar and sealed to create an insulating gap. This gap is typically filled with regular air or other gases (such as argon), enhancing thermal and acoustic insulation properties. The double layer of glass significantly reduces heat transfer and noise infiltration compared to single-glazed windows, and as expected, is a costlier option. Nowadays, these types of windows are referred to as Insulated Glass Units (or IGUs).
Where are double-glazed windows and single-glazed windows used?
Single-glazed windows are commonly found in older buildings, homes and other structures that have a single-glazing framework, which would need to be replaced by a builder prior to installing double-glazed glass. They are also used as a budget option or in several instances where double-glazed glass cannot be used, such as:
- Balustrades and Pool Fences
- Cabinet Glass
- Shower screens
- Splashbacks
- Tabletops
- Wired Glass
Double-glazed windows are typically prevalent in newer constructions and buildings located in regions with more volatile weather conditions. This is because of their superior insulation properties which make them ideal for homes and offices in areas with fluctuating hot or cold climates.
Double-glazed windows are becoming increasingly common to mitigate climate concerns, and in urban settings to mitigate noise pollution like main road and air traffic, where the owner/builders want to ensure a quieter indoor environment.
The Benefits of Double-Glazed windows (over Single-Glazed windows)
Double-glazed windows offer several advantages over the single-glazed alternative:
- Double-glazed windows provide better insulation, reducing energy consumption and lowering heating and cooling costs for occupants.
- The dual glass panes and their insulating gas layer significantly reduce noise levels, enhancing indoor comfort.
- Double-glazed windows can improve window security, as they are harder to break when compared to single-glazed options. Whilst double-glazed windows are the costlier option for windows compared to than single-glazed windows, this type of window can help to save money in the long term with lower energy costs, improved safety and increased comfort.
That said, as discussed, there are also many instances in which single-glazed glass are perfect for your home or business and is what you require.
But the benefits of double-glazed windows make this option a worthwhile consideration when assessing what windows to install in your home or business, as they may well be worth the investment, and add to the overall value and enjoyment of your property.
