How much do aluminium windows cost in Australia?

Aluminium windows may be prized for their durability, but they’re not exempt from wear and tear. If yours are at the brink of surrendering to built-up grime and rust after years of use, or if a simple glass repair won’t be enough to revive them, then you’re due for a window replacement project.

Learn more about the different factors that can affect aluminium window costs and how you can improve your home’s comfort without going beyond your budget.

The prices of aluminium windows vary across Australia. Labour rates, local demand, and availability of suppliers can all play a part in the final calculation. If you’re from a major city, for instance, you’d typically encounter higher installation costs than in regional areas.

Below is an aluminium windows price list (supply only) for different areas across the country, based on available third-party pricing.

The window style you choose may also be a determining factor in the overall price. Some designs tend to require more materials, hardware, or manufacturing than others, so keep that in mind when planning around a budget.

Sliding windows

If you’re after something practical, aluminium sliding windows are hard to beat. Their horizontal sliding design suits areas with limited outdoor space, making them one of the most popular window styles in Australian homes.

Expect to pay around $350 for a standard-sized sliding window. Wider options or customised configurations cost more.

Awning windows

Awning windows are hinged at the top and open outward from the bottom, allowing proper ventilation, even during light rain. They’re typically installed where airflow matters most, such as kitchens and bathrooms.

Prices start at $205 for smaller windows in this style, with larger sizes reaching around $975.

Double-hung windows

Double-hung windows have two movable sashes that slide vertically, letting you open the top, bottom, or both for better airflow. This design is timeless and suits both classic and modern Australian homes.

Supply-only prices generally start at $600, with higher prices for larger sizes and premium glazing.

Casement windows

Casement windows are a popular choice for living rooms and bedrooms where maximum ventilation is a must. Hinged on one side and open outward like a door, this window type offers plenty of fresh air and, even better, an unobstructed view.

Standard casement windows cost around $380. Premium brands may also charge more, so it’s worth comparing Stegbar aluminium windows prices with other manufacturers before locking in a decision.

Louvre windows

Louvre windows are made of horizontal glass blades that can be angled to control airflow while still keeping the indoors concealed from public view. This is why they’re a staple choice for bathrooms and laundry areas, where you probably wouldn’t want to choose between proper ventilation and privacy.

Prices range from $300 to $600, depending on the window size and number of louvre blades.

Bifold windows

If you want a smooth connection between your indoor and outdoor spaces, bifold windows are an excellent choice. Their folding panels open up wide, making them a go-to option for kitchens, entertaining areas, and servery windows.

Supply-only prices tend to vary considerably, but the typical cost is around $1,250 per m².

Here’s a quick summary of prices per aluminium window type:

Factors that affect aluminium window costs

While window style is a crucial consideration, your quote relies heavily on other factors, from the size of your window to the complexity of the installation process.

Knowing exactly what might impact the cost can help you compare quotes much more confidently and save yourself the trouble of paying for upgrades you may not need.

Window size

As a general rule, bigger windows cost more since larger frames require more aluminium and glass. On the other hand, custom sizes and specifications, such as getting oversized panels or unusual shapes, typically increase manufacturing costs.

Glazing

The type of glazing you go for has a major impact on both the final cost and the window’s performance once it’s installed. Standard single-glazing is the most affordable choice, but options that come at a higher price, such as acoustic glass, laminated glass, Low-E glass, or double-glazed windows, offer more benefits, including energy efficiency, insulation, and noise reduction.

Frame finish and colour

If you’re working with a tighter budget, standard aluminium finishes are generally the most cost-effective. If you have more wiggle room for prices, powder-coated or anodised finishes offer greater durability and a wider choice of colours at higher rates.

Installation complexity

Aluminium window installations aren’t always straightforward. If old windows need to be removed or are on an upper storey, or if the installation requires any form of structural modification before the new frames can be fitted, prices are expected to go up.

Number of windows

Replacing several windows at once is often more economical than completing the project in stages. Many suppliers and installers offer bulk discounts, helping reduce the average cost per window.

Location

Where you live can also affect the overall cost of aluminium windows in Australia. Labour rates are generally higher in major cities like Sydney and Melbourne, while regional areas may incur additional travel costs if the installer you hire is based elsewhere.

As you’ve read, you have the option to either buy windows as a standalone purchase or as part of a package that includes installation. The ideal choice between these two usually depends on your budget, experience, and the scope of your project.

Buying aluminium windows and doors on a supply-only basis can be a smart way to save money if you’re replacing an existing window of the same size or already have a qualified handyman or licensed builder lined up. It also gives you the freedom to compare products from different suppliers and shop around for the best deal.

However, if you’d rather leave the hard work to the professionals, a supply-and-install package is often the more convenient choice. Professional installation typically costs around $40 to $50 per hour, although the final labour cost per window depends on the specifics of the job.

While hiring professionals to supply and install new aluminium windows costs more upfront, this option ensures that the fitting is correct and the project is compliant with Australian building standards.

Getting aluminium windows doesn’t have to break the bank. Here are simple ways you can keep costs down while still investing in quality windows that’ll last you for years:

• Choose standard window sizes rather than custom-made designs, unless necessary or if working with a higher budget. The former is usually more affordable and easier to source.

• Compare quotes from several suppliers and installers before finalising your decision.

• Stick with standard frame colours and finishes if you’re looking to reduce upfront costs.

• Only upgrade to double glazing, acoustic glass, or Low-E glass if the extra performance is worth the added expense.

• Check whether hardware such as locks, hinges, winders, flyscreens, and other accessories are included in the quote.

• Schedule your installation alongside other renovation work to help reduce labour costs.

• If insects are a concern, ask whether retractable flyscreens can be bundled with your window purchase instead of buying them separately.

What to look for in a window installer

Even the best aluminium windows won’t perform well if they’re installed incorrectly. It’s always worth taking the time to choose an experienced installer who can fit your new windows safely and to a high standard, saving you on future window repairs.

Licensing requirements for glaziers and window installers vary by state and territory, so it’s a good idea to check what’s required where you live. If possible, look for a licensed and insured professional with experience installing aluminium windows.

Membership with industry organisations such as the Australian Glass & Window Association (AGWA) can also be a good sign that they follow recognised industry standards.

Before hiring an installer, consider asking the following:

• Are you licensed and insured for this type of work?

• How much experience do you have in installing aluminium windows?

• Does the quote include the removal and disposal of old window frames?

• Are materials, hardware, and glazing included in the quoted price?

• What warranty do you provide on workmanship and materials?

• How long will the installation take?
