Double Glazed Windows and Doors with clear glass



Double glazing windows and doors may have long been popular in colder climates, but they’re a valuable asset in warmer climates too. There are several lesser-known benefits of double glazing over single glazed windows and doors. So in this blog post, we’re exploring their many benefits.


Double glazing windows and doors have panels that consist of two pieces of glass bonded together with a spacer between them.

This space is hermetically sealed and filled with argon gas.

Structurally, these gas-filled, separated panes are the critical difference between double glazed products and their single glazed counterparts.

However, this fundamental difference results in a world of difference when it comes to outcomes and benefits.


The space between the two pieces of glass acts as a thermal barrier between your home and the outside environment.

This space makes them more effective insulators than standard windows and doors. They keep your home’s temperature steadier and insulate you from the full effects of temperature extremes.

By reducing your heat loss and gain, you can keep your home cooler in summer and warmer in winter – which is what everyone wants.


Almost half the energy used in Australian homes goes to powering heating and cooling devices, according to the Australian Government’s sustainable home guide.

By reducing your heat loss and gain, double glazing windows and doors reduce your need for this electrical temperature control.

As such, they can reduce your energy costs by more than 20% compared to a house with single-glazed windows and doors.

That’s some serious energy efficiency.

Condensation occurs when the moist air inside your home is exposed to a cooler surface such as a single glazed window.

While condensation is generally just an annoyance, it does have the potential to cause severe problems for your home.

Double glazing products reduce the likelihood of condensation by removing its key cause – a cold window. The interior glass pane stays close to room temperature, reducing your condensation risk.


The space between the two glass panes doesn’t just insulate you from temperature extremes – it also minimises external noises.

This air gap allows double glazed products to absorb more sound energy than single glazed windows and doors.

Special acoustic seals along with acoustic layers within the glass can also be added to increase the acoustic effectiveness of double glazing.

Aesthetically-speaking, all our double-glazing windows and doors have profiles that are uniform across the range.

Meaning they’re not just architecturally symmetrical with one another. They are also architecturally symmetrical with our other windows and doors.

This symmetry gives you greater flexibility in choosing the most suitable windows and doors for you.


As you can see, there are lots of benefits to choosing double glazing windows and doors.

If energy efficiency and insulation against temperature and noise are what you’re looking for, double-glazed products are probably the way to go.

But if you’re still having trouble deciding, we recommend asking for a comparison quote. You (or your client) can compare your single- and double-glazed options side-by-side, while still keeping the benefits we’ve discussed in mind.

Choosing the right windows and doors can be a challenge, especially if you’re new to the process. Our selection guideline will help you find the correct windows and doors for your project.
