If you are pricing a Melbourne new build, townhouse package or window replacement, the search you type is usually some version of double glazed windows cost or cost of double glazed aluminium windows. The honest answer is a range - and the range only tightens once opening sizes, glass, access and install scope are known.
Typical Melbourne price ranges (2026)
As a local aluminium manufacturer quoting weekly across greater Melbourne, these are the bands most projects fall into. They are guides for estimating, not a fixed price list.
- Standard residential double glazed aluminium window, supply & install: about $2,200-$3,800 each
- Larger fixed panels, corner windows or complex shapes: $3,500-$6,000+ each
- Supply-only trade pricing for builders (labelled site delivery): commonly 20-35% under installed retail
- Whole 3-bedroom home replacement: often $15,000-$40,000 depending on count and glass
- Premium acoustic / high-performance Low-E IGUs: add roughly 10-25% on the glass line
What moves the cost up or down
1. Opening size and configuration
A small awning is not priced like a 3-panel sliding door. Stackers, bifolds and corner openings need more extrusion, hardware and glass - and often crane or two-person site handling.
2. Glass specification
Clear double glazing is the baseline. Low-E coatings, argon fill, warm-edge spacers and laminated acoustic glass each add cost and performance. Builders chasing 7-star energy reports should lock glass early with their energy consultant.
3. Frame system - standard vs thermally broken
Thermally broken aluminium inserts a polyamide barrier in the frame. It costs more than a standard aluminium section but reduces frame heat transfer and condensation risk - important on west elevations and NCC energy compliance.
4. Supply-only vs supply & install
Builder window supply Melbourne jobs are usually supply-only: we fabricate to your schedule, label per opening, and deliver to site or yard. Homeowner replacements more often include install. Mixing scopes without a clear schedule is where quotes blow out.
Builder vs homeowner pricing
Trade accounts get schedule-based quoting, consistent powder-coat batches across multi-unit sites, and staged delivery. Retail homeowners get free measure, itemised openings and install options. Same workshop - different workflow.
How to get an accurate number
- Send a window schedule or mark-ups with rough opening sizes
- Note glass targets (U-value / SHGC) from the energy report
- Flag install access issues - scaffolding, upper levels, occupied homes
- Confirm colour and hardware early to avoid rework
