How Much Do Aluminium Windows Cost? — The Ultimate Homeowner’s Guide
Introduction — Why Aluminium Windows Are Worth Every Cent
When it comes to upgrading your home, aluminium windows are one of the smartest investments you can make. They offer sleek design, low maintenance, energy efficiency, and long-lasting performance — all while adding tremendous value to your property.
But one of the first questions homeowners ask is: “How much do aluminium windows cost?”
The answer depends on several factors, including size, glass type, configuration, and installation. In this comprehensive guide, we’ll break down all the elements that determine the price of aluminium windows in Australia — so you can make a confident and informed choice.
1. Average Cost of Aluminium Windows in Australia
Let’s start with the basics. On average, aluminium windows cost between $450 and $1,200 per square metre, depending on design and glazing specifications.
Here’s a breakdown by type:
| Window Type | Average Supply Cost | Average Installed Cost |
|---|---|---|
| Fixed Window | $300 – $800 | $600 – $1,000 |
| Sliding Window | $400 – $1,000 | $700 – $1,400 |
| Awning Window | $500 – $1,200 | $900 – $1,700 |
| Double-Hung Window | $600 – $1,400 | $1,000 – $1,900 |

2. Key Factors That Affect Aluminium Window Costs
Several factors influence the price of aluminium windows. Understanding these can help you plan your project and budget effectively.
a. Window Size and Configuration
Larger windows require more aluminium framing and glass, which naturally increases cost. Complex configurations such as corner windows or stacking systems also demand additional framing and labour.
b. Glass Type
-
Single Glazing: Most affordable but less energy efficient.
-
Double Glazing: Costs 30–40% more but drastically improves insulation and noise reduction.
-
Low-E or Tinted Glass: Adds UV protection and reduces heat gain — ideal for Melbourne’s climate.
c. Frame Finish
Standard anodised aluminium is cost-effective, while powder-coated finishes (available in over 100 colours) add visual appeal but slightly increase price.
d. Installation Complexity
If old frames need to be removed or structural adjustments are required, expect higher labour costs.
e. Customisation Options
Non-standard shapes, configurations, or matching heritage styles may add to manufacturing costs.
At EZ Windows, our direct-to-customer approach eliminates middlemen — meaning you only pay for what you need, not inflated retail mark-ups.
3. Comparing Aluminium to Other Window Materials
To understand value, it helps to compare aluminium windows with other common materials:
| Material | Cost Range (Installed) | Lifespan | Maintenance | Notes |
|---|---|---|---|---|
| Aluminium | $600 – $1,800 | 30+ years | Low | Strong, sleek, weather-resistant |
| uPVC | $500 – $1,500 | 20–25 years | Low | Good insulator, less rigid |
| Timber | $700 – $2,000 | 15–20 years | High | Classic look but requires painting |
| Steel | $1,500 – $3,000 | 50+ years | Medium | Premium cost and industrial style |
While aluminium isn’t always the cheapest option, it’s the most cost-effective over time, thanks to its durability, energy efficiency, and modern aesthetic.
4. How Much Does It Cost to Replace Old Windows with Aluminium?
Replacing existing windows with new aluminium units generally costs between $800 and $2,000 per window, including removal, disposal, and installation.
Factors that affect replacement pricing include:
-
Condition of the old frame
-
Wall structure (brick veneer, timber, or concrete)
-
Accessibility (ground floor vs second storey)
With EZ Windows, we handle everything — from precise measurement and manufacturing to installation and clean-up — so your renovation is effortless and stress-free.
5. Why Aluminium Windows Are a Smart Long-Term Investment
Many homeowners focus only on upfront cost. But when you consider performance and lifespan, aluminium windows offer unmatched long-term value:
-
Longevity: Aluminium won’t warp, crack, or swell like timber.
-
Energy Efficiency: Modern thermal break technology reduces energy bills.
-
Low Maintenance: No need for repainting or resealing.
-
Aesthetics: Sleek, minimal frames enhance natural light and curb appeal.
-
Durability: Built to withstand Melbourne’s changing weather conditions.
That’s why architects, builders, and homeowners alike continue to choose aluminium as their preferred window material.
