Let’s be honest—Australian weather can be brutal. Whether it’s a 40-degree Sydney heatwave or a freezing Melbourne winter night, our houses often feel like they have no protection. We crank up the AC or the heater, and we watch our hard-earned money leak straight out the window.
If you are building or renovating, you’ve probably heard about the advantages of double glazed windows. But is it really worth the investment?
As a top windows and doors supplier in Australia, we don’t just import windows; we are an Australian-based powerhouse that designs and manufactures high-performance systems for our unique climate. With over 30 years of expertise and a massive 60,000㎡ advanced manufacturing base, we know exactly what it takes to keep an Aussie home comfortable.
Here is your simple guide to why a double glazed window is the best investment you can make for your home.
What Exactly is a Double Glazed Window?
Before we dive into the perks, let’s get the basics right. An awning window definition (or any window type) is simple: it’s about the frame and the glass.
A double glazed window consists of two panes of glass with a sealed space in between. This space is filled with air or Argon gas, acting as a thermal shield. Think of it like a high-tech “puffer jacket” for your house.
The Top 4 Double Glazed Windows Benefits
There are many advantages of double glazed windows, but for most Australians, it comes down to these four game-changers:
1. Massive Savings on Energy Bills
This is the number one reason people switch. One of the primary benefits of double glazing is heat retention. In winter, it keeps the warmth inside. In summer, it blocks the scorching heat from entering. This can reduce your heating and cooling costs by up to 30%.
2. Peace and Quiet
If you live near a busy road in Brisbane or under a flight path in Sydney, you know how annoying noise can be. Double glazing is a world-class sound barrier, significantly reducing external noise so you can finally get a good night’s sleep.
3. No More “Crying” Windows
Tired of waking up to fogged-up glass and mouldy sills? Because the inner pane stays closer to the room temperature, it reduces condensation, keeping your home healthier and drier.
4. Better Home Security
Two panes of toughened glass are much harder to break than one. When you combine this with Jolong’s multi-point locking systems, you have a home that is truly a fortress.
Spotlight: Awning Type Windows for the Australian Lifestyle
One of the most popular ways to enjoy the benefits of double glazing is through our awning range. Awning type windows are hinged at the top and open outward from the bottom. They are incredibly practical because you can leave them open for fresh air even when it’s raining!
- [Large Awning Window] Solutions: If you have a room with a view, a large awning window can flood your space with light while maintaining incredible energy efficiency.
- [Stacked Awning Windows]: For a modern architectural look, many designers choose stacked awning windows. This allows you to have multiple opening sashes in one tall frame, giving you total control over airflow.
- The [Awning and Casement Window] Combo: Can’t decide? You don’t have to. Combining an awning and casement window in the same room creates a balanced look with maximum functionality.
