How Useful Are Double Glazed Windows In Summer? Facts, Myths And How-To

Myth: Double Glazed Windows Make Your Home Even Warmer In The Summer

There’s a misconception that double glazed windows heat your home. In actuality, the science behind double glazed windows simply makes them a barrier for heat to escape. Meaning, that it doesn’t magnify the outside temperature indoors, it simply keeps the indoor temperature warmer for longer. So in reality, when the summer sunshine rolls in, double glazed windows keep heat out of your home.

Myth: Opening The Window Cools The House Down More In The Summer

In any other climate, this could be true. But for the Australian climate where humidity spikes up to 65% in the summer, opening the window allows warm air to circulate into your home.

Fact: Closing Your Double Glazed Window Will Keep Your Home Colder

Although it may appear counterintuitive, closing your double glass windows in extremely hot weather might actually make your home feel cooler, thanks to how much they reflect heat.

If you do need additional fresh air, both our uPVC and Aluminium double-glazed windows feature a trickle vent mechanism that allows air to circulate even if the windows are entirely closed. 

Fact: Double Glazed Windows Protect You From UV Rays 

If you’ve ever changed your carpet before and noticed some discolouration, chances are that it’s not just dirt or wear & tear. More likely than not, sunlight did that damage over a long period of time.

Renowned as the biggest contributor to fading and discolouration, UV rays are the culprit behind 45% of fading and discolouration. On the other hand, infrared and other sources of visible light contribute by up to 25%. 

So what does this have to do with double glazed windows? They combat UV rays. Ordinary glass on its own can filter out a large amount of UV in the light that passes through it. Double glazing has two glass panes that do so, as well as the inert gas in between. If anything, not only can it protect your furniture, but it can also protect you from that Australian summer sunshine. 

How to Customise Double Glazing FOR The Summer

While on the topic of glass, different types of panes offer different types of protection based on what your home needs most this summer. Here at Ecostar, we make sure you’re spoilt for choice when it comes to choosing the right materials for your home. Examples of these include:

Laminated Glass

Laminated glass is not only tougher and more durable than ordinary glass, but it can also filter out up to 95% of UV Rays. It helps if you think about the glass panes of the window as two separate filters, with the first filtering out almost all the UV rays, and the second blocking out what’s left, making laminated double glazing a very suitable option for sunnier climates.

Sound Reduction Glass

Everyone knows that summer is the best time of year to get together with friends. As nice as it sounds, it does bring the season of noisy neighbours. Our sound reduction glass features a very broad outer pane and an even thicker inner pane which is purpose-built for blocking out the noise of those pesky neighbours.

Low Emissivity Glass

Through the use of an invisible coating, we’ve incorporated the use of low-e, or low emissivity glass into our energy efficient builds. 

Much like how we explained how double glazing works, low-e glass also reflects heat out of and into the household. This means if you use this material in combination with double glazing, it serves to reflect even more heat away from your home, keeping you cooler for longer.

Security Glass For When You’re On A Summer Getaway

On its own (even without using the security glass) double glazed windows are structured in a way that makes them harder to break and deform. But combined with our security glass, which is five times harder to break through than standard window glass, you can rest assured that your home is well-equipped with security measures to prevent any would-be thieves.
