7 Factors That Affect Aluminium Window Prices in Australia

1. Size and dimensions

The size of the aluminium windows in your home or premises will play a major role in the final cost. Bigger windows require more raw materials, potentially more complex fabrication processes and additional labour for installation. All these factors contribute to a higher price tag. Oversized or custom-sized windows may also need reinforcing for frames or extra structural support, and this will add even more to the total cost.

For better affordability, choose a standard window size. This is typically more affordable because manufacturers can mass-produce standard windows in larger quantities, which reduces manufacturing and supply costs. 

2. Window type and design

The style and functionality of your aluminium windows will affect the price. Basic designs like sliding windows are more affordable thanks to their straightforward construction and ease of installation. Meanwhile, styles such as awning, casement or bi-fold windows tend to cost more because they have additional moving parts, specialised hardware and intricate manufacturing requirements.

Custom configurations such as multi-panel setups or unusual shapes will raise the final price further. When you set your budget, before you get too attached to looks, consider the practicality of the design you choose.

3. Glazing options

Glazing also plays a pivotal role in the overall cost of aluminium windows. For instance, single-glazed windows are the most budget-friendly option, but they offer less insulation and noise reduction compared to double-glazing. While they are more of an investment, double-glazed windows provide optimal insulation, noise reduction and energy efficiency. This upfront expense has the power to pay off in the long run.

If you’re looking for even more window benefits, specialty glass options like tinted, low-E or laminated glass can enhance privacy, UV protection and security. However, they will also add to the final price. Choosing the right glazing depends on your climate, lifestyle and budget.

4. Frame quality and finish

Another key factor that affects the price of aluminium windows is the quality of the frame. Thicker, higher-grade aluminium frames offer greater strength, durability and resistance to warping but naturally cost more than lighter, thinner options.

The finish you choose also affects the cost. Standard powder-coated colours are often part of the base cost, but if you want custom colours, anodised finishes or premium woodgrain effects that emulate timber, expect to pay extra. 

Investing in higher frame quality and tailored finishes can enhance both the performance and visual appeal of your windows.

5. Energy efficiency requirements

Windows with higher energy efficiency will need upfront investment because features like thermal breaks or advanced glazing cost more to manufacture and install. These designs help reduce heat transfer, keeping homes cooler in summer and warmer in winter, which can lead to significant energy savings over time.

Choosing energy-efficient aluminium windows is not just about meeting building standards. It’s also a smart choice for long-term comfort and lower electricity bills.

6. Installation complexity

If your new aluminium windows require complex installation processes, this will add to the total. If your site is easily accessible and the installation is straightforward, labour costs will generally be lower.

More challenging projects that require extra time, equipment, and expertise will cost more for installation. Examples include:

• Fitting windows in high-rise buildings
• Hard to reach areas
• Older homes that require structural modifications

Always factor in installation conditions when you budget for your new aluminium window project.

7. Additional features

Extra features increase the overall cost of an aluminium window. Insect screens and security locks are examples; they add functionality but require additional materials and installation work.

While these features may seem like small additions, they will affect the final price.
