How Much Do Aluminium Windows Cost Per m²?
Introduction: Why Cost Per Square Metre Matters
When it comes to custom aluminium windows and doors, one of the most common questions Melbourne homeowners ask is:
“How much will it cost per square metre?”
Unlike buying a fridge or a sofa, where pricing is clear and fixed, window pricing can be complex. The cost per m² depends on a variety of factors: size, glazing, frame finish, hardware, and installation requirements.
But understanding cost per m² is essential for:
-
Budgeting new builds and renovations.
-
Comparing aluminium to other materials (uPVC, timber).
-
Evaluating suppliers (Bunnings vs custom manufacturers).
-
Calculating long-term value.
This blog will provide a comprehensive breakdown of aluminium window costs per m² in Melbourne, including real-world examples, case studies, and the benefits of going custom with EZ Windows ComfortEdge.

Across Melbourne, aluminium windows typically fall into the following ranges:

2. What Factors Affect Aluminium Window Costs Per m²?
✅ 1. Size & Shape
Larger windows cost more, not just in glass but in thicker, stronger aluminium frames. Unusual shapes (arched, trapezoid) also increase fabrication costs.
✅ 2. Glazing Type
-
Single Glazing: Cheapest option, but poor insulation.
-
Double Glazing: Adds 20–40% to cost but saves up to 30% in energy bills.
-
Laminated or Acoustic Glass: Essential for urban areas; adds further premium.
✅ 3. Frame Profile
-
Standard aluminium profiles = cheaper.
-
Slimline or thermally broken = premium.
✅ 4. Finish & Colour
-
Powder coating in standard colours (white, black, silver) is often included.
-
Custom finishes (timber-look, anodised, specialty colours) add 15–30%.
✅ 5. Hardware & Accessories
High-quality locks, handles, restrictors, and flyscreens impact pricing.
✅ 6. Installation Complexity
Second-storey, tight access, or heritage builds push up installation costs per m².
3. Aluminium vs Other Window Materials (Per m²)
| Material | Average Cost per m² | Pros | Cons |
|---|---|---|---|
| Aluminium | $280 – $1,200 | Sleek, modern, durable, low maintenance | Conducts heat (unless thermally broken) |
| uPVC | $200 – $600 | Affordable, insulating | Bulkier, limited colour range, less durable in heat |
| Timber | $450 – $1,500 | Classic, heritage look | High maintenance, expensive, prone to rot |
| Steel | $1,000 – $2,500 | Ultra-slim, architectural | Expensive, heavy, limited suppliers |
👉 Verdict: Aluminium offers the best balance of price, durability, and design flexibility.
