Double Glazing - What is it?

Double glazed windows are also known as double-pane windows or insulated windows.
In simple terms, double glazing comprises of two separate glass panes bonded together by a spacer and separated by a gap of approximately 6mm to 20mm. The gap is then sealed and acts as a break between the inside and outside pieces of glass.

The Benefits of Double-Glazing Windows
Heightened Security
Double-glazed windows are constructed with two layers of glass and are more resistant to impact, in comparison to single-paned windows- potentially making it more difficult for intruders to gain access to your home.
Double Glazing Saves Money
Lower Energy Bills - energy costs have increased significantly in Australia over the last decade. With some significant increases in more recent times, with our country struggling to keep inflation under control, post COVID. An interesting fact is approximately half the energy used in Australian homes is used to power heating and cooling devices. Therefore, keeping your home cool in summer and warm in winter has become more unaffordable than ever before.
Double-glazed windows provide improved thermal insulation, meaning that less energy is required to heat or cool the interior of your home. Double-glazed windows are a great feature of a home allowing for the heating and cooling systems to operate more effectively by consuming less energy, ultimately resulting in lower power bills.
Not only are double-glazed windows energy efficient, they are also more durable than single-pane windows due to their construction and are less prone to breakage and damage.
Reduces Noise
Due to the gap between the glass panes, double glazed windows can significantly absorb more sound energy than standard single products. Making double-glazed windows a key contributor to reducing outside noise, such as vehicles, planes, trains, people, animals and other sources - well over 50% compared to single glazing.
Condensation
Condensation occurs when moist air inside your home is exposed to a cooler surface, such as a single glazed window. Whilst condensation normally is just an annoyance, it does have the potential to cause severe problems for your home, such as moisture damage, reduced energy efficiency and respiratory issues.
Double glazed windows are a great contributor in removing the key cause of condensation – a cold window. The interior glass pane of the two panes stays close to room temperature, reducing any potential condensation risk.
Easy to maintain, double glazed windows have two panes of glass that are well-sealed to help prevent humidity and dust from creeping into hard-to-reach places.
Increases Home Value
A home with double glazed windows will improve the value of your home based on all the benefits outlined above.
Furthermore, your home will appeal to prospective buyers who place a high value on energy efficiency/sustainability as they value the long-term savings associated with homes that come equipped with double glazed windows.
Not only are double glazed windows an attractive and durable solution, they will also protect the interior of your home and provide additional comforts such as noise reduction and more consistent indoor temperatures.

How much does double-glazing cost?
Installing double glazed windows to an existing home can be costly and time consuming, as it involves re-plastering, redecorating, and refitting blinds and curtains. Also, you must be wary if any of your existing windows are built in load bearing walls, it creates further complexities and challenges. When you choose windows with double glazing in your new build home, none of these items pose an issue as you will move into a brand new home with all windows and doors installed with double glazing.

New builds have double-glazing already
This is a fallacy!
One thing you need to be cautious of as a new home buyer is understanding what is included in each home. With several new home builders, the house inclusions (also known as standing inclusions; inclusions; specifications, spec) outline all inclusions. Be wary as several builders have different inclusions for different house designs, not always a one size fits all approach. For example, at JG King Homes Alpha homes are a different set of house inclusions to Up homes, etc.
Double glazing currently is not a house inclusion for several builders or builder housing ranges. So do your due diligence and make sure you know what you are getting with your home.
