What is the Cost Estimate for Aluminium Windows?
Introduction: Why Cost Estimation Matters
When planning a new build, renovation, or window replacement, homeowners and builders in Melbourne often ask:
“What’s the cost estimate for aluminium windows?”
Unlike flat-rate products, aluminium windows have variable pricing. The final cost depends on size, design, glass type, energy requirements, finishes, and installation complexity. Getting an accurate cost estimate upfront is essential to:
-
Avoid budget blowouts.
-
Compare options (Bunnings vs custom).
-
Plan energy-efficient upgrades.
-
Select the right supplier.
In this guide, we’ll explore how aluminium window costs are estimated, provide real-world Melbourne case studies, compare alternatives, and explain why custom aluminium windows and doors from EZ Windows ComfortEdge provide the most accurate and cost-effective solutions.
1. Typical Cost Range for Aluminium Windows
In Melbourne and across Australia, aluminium window costs generally fall into the following ranges (supply only):
| Window Type | Average Price (AUD) |
|---|---|
| Sliding Aluminium Window | $280 – $550 |
| Awning or Casement Aluminium Window | $300 – $600 |
| Fixed Aluminium Window | $250 – $450 |
| Double Glazed Aluminium Window | $450 – $950 |
| Thermally Broken Aluminium Window | $650 – $1,200+ |
| Custom ComfortEdge Aluminium Window (EZ Windows) | $500 – $950 |
👉 Installation adds approx. $150 – $300 per m². Complex installations (e.g., second-storey, heritage properties) may cost more.
2. Factors That Affect Cost Estimates
When estimating the cost of aluminium windows, suppliers and installers take into account the following:
✅ Size & Design Complexity
-
Larger or uniquely shaped windows increase both material and labour costs.
-
Complex configurations like sliding-stacking doors or bifolds cost more than a fixed pane.
✅ Glazing Options
-
Single Glazing = baseline cost.
-
Double Glazing = adds 20–40% upfront but provides energy savings.
-
Acoustic/Laminated Glass = premium option for noise reduction and safety.
✅ Frame Profile
-
Standard Aluminium = affordable and durable.
-
Slimline/Architectural = premium look at higher cost.
-
Thermally Broken Aluminium = prevents heat transfer, higher upfront cost but lowers long-term energy bills.
✅ Finishes & Colours
-
Standard powder coating is included.
-
Timber-look or anodised finishes add 15–30%.
✅ Installation Factors
-
Ease of access, removal of old windows, scaffolding, and compliance requirements can all affect estimates.
3. Aluminium Window Cost Estimate vs Other Materials
| Material | Average Price (AUD) | Pros | Cons |
|---|---|---|---|
| Aluminium | $280 – $1,200+ | Strong, slim, low maintenance | Conducts heat unless thermally broken |
| uPVC | $200 – $600 | Budget-friendly, insulating | Bulky, less aesthetic flexibility |
| Timber | $450 – $1,500 | Warm, natural look | High maintenance, prone to rot |
| Steel | $1,000 – $2,500 | Ultra-thin profiles, high strength | Expensive, fewer suppliers |
👉 Aluminium sits in the mid-range for cost but delivers excellent durability and design flexibility.

5. Why Custom Estimates Are More Accurate
Big-box retailers like Bunnings may advertise “standard aluminium window prices”, but those often don’t reflect:
-
On-site measurement requirements.
-
Compliance with energy efficiency ratings.
-
Unique architectural requirements.
-
Long-term durability expectations.
EZ Windows provides instant online cost estimates with precise dimensions. No hidden fees, no guesswork — just an accurate price tailored to your project.
6. Long-Term Cost Considerations
When estimating costs, think beyond upfront pricing.
-
Maintenance: Aluminium requires minimal upkeep compared to timber.
-
Energy Efficiency: Double glazing and thermal breaks lower heating/cooling costs.
-
Lifespan: Aluminium windows last 30–40 years, spreading cost over decades.
👉 While initial estimates may look higher than cheaper options like uPVC, lifetime value is superior with aluminium.
