Specifying aluminium windows for new builds Melbourne requires more care than at any point in the city’s history. Specifically, from May 2025, every new home and major renovation must meet a minimum 7-star NatHERS rating. Notably, this lifts the bar from the previous 6-star benchmark. Furthermore, buyers now expect floor-to-ceiling glass and indoor-outdoor connection as a baseline. Additionally, the Victorian climate demands framing that handles genuine extremes. For example, cold mornings, hot afternoons, coastal salt in the bayside, and frosts in the outer north.
Aluminium remains the dominant framing material for Melbourne new builds. Indeed, the reasons run as technical as they are aesthetic. Specifically, modern thermally broken aluminium with double glazing routinely achieves whole-window U-values of 1.8–2.5 W/m²K. Notably, this comfortably matches the range certified energy assessors target for 7-star outcomes. Furthermore, aluminium frames typically last 45 years or more. By comparison, the most common alternatives last 20–30 years. Additionally, aluminium’s strength-to-weight ratio supports slim sightlines and oversized openings without compromise.
Aluminium Windows for New Builds Melbourne: Suburb-by-Suburb
Melbourne is not one climate or one design brief. Consequently, window specification needs to flex with the suburb, the streetscape, and the site’s regulatory environment.
- Bayside and coastal (Brighton, Sandringham, Mentone, Williamstown) — salt-laden air calls for marine-grade powder coating systems. For example, Dulux Alphatec delivers corrosion resistance suited to coastal exposure.
- Inner suburbs (Carlton, Fitzroy, Richmond, South Yarra, Prahran) — heritage overlays and tight sites demand custom-sized glazing and slim sightlines. Notably, builders increasingly specify steel-look black aluminium. Specifically, this suits warehouse conversions and contemporary infills.
- Eastern suburbs (Camberwell, Hawthorn, Kew, Balwyn, Glen Iris) — premium new builds typically call for the Architectural Range. Furthermore, the Ultra Low-Profile Series and Designer Door Range deliver the refined sightlines this market expects.
- Growth corridors (Craigieburn, Mernda, Tarneit, Point Cook) — volume new homes need cost-effective products that still meet 7-star NatHERS. Notably, we achieve this without compromising on weather performance or buildable glazing area.
- Outer south-east (Berwick, Cranbourne, Officer, Pakenham) — family homes on larger blocks suit expansive sliding stackers and bi-fold openings. Specifically, these are applications where aluminium’s structural capacity proves decisive.
- Bushfire-affected fringes (Warrandyte, Eltham, Hurstbridge, the Yarra Ranges) — compliance with AS 3959 and BAL ratings is mandatory. Notably, aluminium integrates into compliant systems up to BAL-FZ.
City Aluminium services all of these suburbs across Greater Melbourne and beyond. Furthermore, local manufacture out of our Melbourne facility tunes specification responses to Victorian conditions. Consequently, we do not import them from offshore catalogue defaults. As a result, your specification reflects how Melbourne actually performs across the seasons.
The Nationwide House Energy Rating Scheme (NatHERS) sets the official benchmark all aluminium windows for new builds Melbourne projects must now meet, with detailed climate zone data for Victoria.
Choosing Aluminium Windows for New Builds Melbourne Projects
The Architectural Range suits premium residential, architecturally designed homes and bespoke builds. Specifically, it includes the Ultra Low-Profile Series. Notably, this Series delivers minimal framing and maximum glass. Additionally, double glazing comes as standard. Furthermore, the Designer Door Range delivers sleek lines, expansive glazing and seamless indoor-outdoor flow. Specifically, we offer this across sliding, hinged, bi-fold and stacker configurations.
The Commercial Range covers shopfronts, schools, multi-storey developments, multi-unit residential, hospitality and similar settings where durability, security and scale matter most. Thermal break and double glazing capabilities are available across both ranges, allowing energy targets to be hit without forcing a compromise on aesthetic intent.
Why City Aluminium for Your Melbourne New Build
- Forty years of Melbourne fabrication — operating since 1986. Furthermore, we have built the process knowledge that thermally broken and slim-profile work demands.
- Made and controlled locally — we manufacture every product in our own Melbourne facility. Consequently, we turn around custom configurations without the lead-time risks of imported systems.
- End-to-end One Stop service — we cover manufacture, delivery in our own trucks, installation, retrofit and replacement. Additionally, builders running their own crews can specify supply-only.
- Twelve product types plus bespoke — awning, double hung, frameless, bi-fold, fixed, sliding, louvre and partition windows. Furthermore, hinged, sliding, automatic and bi-fold doors round out the range. Notably, custom configurations come as standard.
- Full finishes library — seven profile families, plus the complete Dulux Duralloy, Duratec, Alphatec, Pearl and Kinetic powder-coat ranges. Additionally, Colorbond colour matching integrates with the facade.

Frequently Asked Questions
Lead times vary with project size, configuration complexity and current order volume. Generally, we manufacture standard configurations in a few weeks. However, thermally broken systems with custom glazing and finishes may take longer. Notably, local manufacture keeps timelines in-house. Consequently, they do not depend on offshore shipping. Furthermore, we recommend booking specification at the framing stage. As a result, the timeline aligns with site readiness.
In most Victorian climate zones, the practical specification combines thermally broken aluminium framing with low-emissivity (Low-E) double glazing. Specifically, this combination typically delivers whole-window U-values in the 1.8–2.2 W/m²K range. Furthermore, we tune SHGC by orientation. Notably, your accredited NatHERS assessor will model the exact requirements for your design and site.
Both options work. Specifically, builders managing their own installation crews can specify supply-only. Furthermore, we deliver to site in our own trucks. However, for projects without a dedicated installation team, our One Stop service covers manufacture, delivery, installation, retrofit and replacement end-to-end.
Yes. We service new builds across Greater Melbourne and throughout Victoria. Specifically, this includes coastal, inner-suburban, eastern, growth-corridor, outer south-east and bushfire-affected fringe areas. Notably, each location carries slightly different specification considerations. For example, coastal salt resistance, BAL compliance, and heritage overlays. Consequently, we tailor product selection accordingly.
The Architectural Range suits premium residential and architecturally designed projects. Specifically, it includes the Ultra Low-Profile Series and Designer Door Range. Notably, these projects prioritise slim sightlines, refined finishes and high thermal performance. By contrast, the Commercial Range serves shopfronts, schools, multi-storey developments, hospitals and hospitality. Specifically, these settings demand higher durability, security and scale. However, both ranges support thermal break configurations and double glazing.
Yes. Notably, aluminium resists combustion. Furthermore, it integrates into systems compliant with AS 3959 across all Bushfire Attack Level ratings up to BAL-FZ. However, your specification needs to consider the entire glazing assembly. Specifically, the glass type and seal materials matter. Additionally, make sure you confirm the correct BAL rating for the site before we begin manufacture.
Cost depends on several factors. Specifically, window size and quantity, glazing specification, frame configuration, finish selection and whether you specify thermal breaks. For example, glazing options include single, double, laminated and tinted. Notably, the fastest way to scope an indicative cost is the City Aluminium online estimator. Furthermore, it captures the variables and returns a tailored estimate.
