How Much Does an Aluminium Window Cost?

Introduction: Why Aluminium Window Costs Matter

When planning a renovation or new build, one of the first questions most homeowners in Melbourne ask is:
“How much does an aluminium window actually cost?”

The answer is not as simple as quoting a single number. Aluminium window pricing varies based on size, glazing, frame design, installation, and supplier. But understanding these costs is crucial for:

• Budget planning.

• Comparing options (Bunnings vs custom-made).

• Deciding between materials (aluminium, timber, uPVC).

• Long-term value analysis (energy savings, lifespan).

This blog will break down the true cost of aluminium windows in Melbourne and Australia, explain the factors that influence pricing, and show why custom aluminium windows and doors from EZ Windows ComfortEdge offer the best combination of performance, style, and affordability.

1. Average Cost of Aluminium Windows in Melbourne

Here’s a breakdown of supply-only prices for different aluminium window types:

👉 Installation adds $150 – $300 per m², depending on access and complexity.

2. What Influences the Cost of Aluminium Windows?

✅ 1. Size & Style

Larger and more complex windows require more materials and labour.

✅ 2. Glazing Choice

• Single Glazing = cheapest, but least efficient.

• Double Glazing = +20–40% upfront, but saves on energy bills.

• Acoustic or Laminated Glass = premium option for urban/traffic areas.

✅ 3. Frame Profile

• Standard aluminium = affordable.

• Slimline/architectural = sleek look but higher cost.

• Thermally broken = essential for performance; slightly more expensive but worth it.

✅ 4. Finish & Colour

• Standard powder coating included.

• Custom finishes (timber-look, anodised) add 15–30%.

✅ 5. Installation Factors

Second-storey, difficult access, or heritage facades increase labour costs.

3. Aluminium vs Other Window Materials

👉 Verdict: Aluminium balances affordability, durability, and style better than alternatives.

4. How Much Do Aluminium Windows Cost in Australia?

Across Australia, aluminium window costs are relatively consistent, though Melbourne and Sydney tend to be slightly higher due to labour and demand.

• Standard aluminium window: $280 – $600

• Double glazed window: $450 – $950

• Architectural slimline/thermally broken: $700 – $1,200+

Custom windows cost more upfront but save in construction adjustments. Builders often find that “cheap” Bunnings windows lead to higher site modification costs — making custom windows cheaper in the long run.
