Double Glazing Cost in Melbourne: A 2026 Price Guide
What double glazing really costs in Melbourne in 2026 — per window, per square metre and whole-home — and how to compare quotes properly.
Double glazing is a significant investment, so it is worth understanding the real numbers before you get quotes. Here are transparent 2026 Melbourne ranges and how to read a quote properly.
Per-window and whole-home ranges
- Standard double glazed window, installed: around $2,200 – $3,000
- Premium (acoustic laminated, larger sizes, sliding doors): $3,500 – $4,500+
- Whole 3-bedroom home (10–15 windows): $15,000 – $40,000+
Per square metre
Many installers quote per square metre for medium-to-large windows — commonly $1,000–$1,800/m² installed depending on glass. Smaller windows carry a higher per-m² rate because fixed handling and installation costs apply regardless of size.
Glass build-up changes the price
- Standard clear double glazing: lowest cost
- Low-E double glazing: modest premium, better thermal control
- Acoustic laminated double glazing: premium, best for noise
- Triple glazing: highest, rarely needed in Melbourne's climate
How to compare quotes properly
Cheaper is not always cheaper. Compare on identical glazing spec, frame system, hardware and installation scope, and confirm whether removal and making good are included. A quote that is 30% lower often has a thinner glass build-up or excludes install.

Common questions
Frequently asked
Standard double glazed windows run about $2,200–$3,000 installed; premium acoustic or large units and sliding doors run higher. Size, glass and access drive the figure.
Yes — larger windows have a lower per-m² rate because fixed handling and installation costs are spread over more area. Small windows cost more per m².
Melbourne's climate rarely justifies the extra cost of triple glazing; well-specified double glazing (with Low-E or acoustic glass where needed) delivers excellent results for less.
