Knowing how to choose window profile correctly sets the foundation for every successful build. Walk into a window manufacturer’s catalogue without a clear plan and the choices can feel overwhelming. Specifically, awning, sliding, double hung, frameless, bi-fold, fixed, louvre, partition. Furthermore, that is before you address profile family, glazing, finish and hardware. However, the choice matters. Get the profile right and the window will perform for forty years. Get it wrong and even the best frame and glass will underdeliver.
This guide walks through the practical decision framework we use at City Aluminium. Specifically, we apply it when working with builders, architects and homeowners across Melbourne. Notably, nearly forty years of fabrication experience has taught us something important. Profile selection is rarely about picking one window. Rather, it is about matching different profiles to different openings within the same build.
How to Choose Window Profile Step 1: Define the Function
Function comes before form. Firstly, map what each opening actually has to do. Is it ventilation-driven, like a bathroom or laundry needing reliable airflow regardless of weather? In that case, an awning window is the workhorse choice. Specifically, it hinges at the top and opens outward. As a result, it sheds rain while open.
Is it about access, where the opening doubles as a passageway? In that case, sliding doors, bi-folds and stackers belong here. Alternatively, is it a fixed view window with no operational requirement? If so, a frameless or fixed picture window maximises glass and minimises framing.
Some openings have multiple functions. For example, a kitchen window above a bench may need to ventilate, frame an outlook, and look refined from both sides. In that case, combinations solve the multi-function brief without compromise. For instance, fixed alongside awning, or sliding alongside fixed. Notably, the City Aluminium range covers awning, double hung, frameless, bi-fold, fixed, sliding, louvre and partition windows.
How to Choose Window Profile Step 2: Match the Architecture
The visible frame is part of the architecture. Specifically, heavy traditional homes can carry chunkier profiles without looking dated. By contrast, contemporary architecture wants slim sightlines that defer to glass and view. Notably, the Architectural Range suits the latter. Anchored by the Ultra Low-Profile Series and Designer Door Range, it suits projects where slim profiles, refined finishes and high thermal performance carry equal weight.
For instance, steel-look black-finished slim aluminium suits warehouse conversions, heritage renovations and contemporary infills. Conversely, bronze, anthracite and Surfmist tones recede into the architecture. Therefore, they suit projects where the frame should sit neutral.
Commercial settings have different priorities. Specifically, shopfronts, schools, multi-storey developments, hospitals and hospitality favour the Commercial Range. In these settings, extensive spans, durability, security and scale carry the priorities. However, the same thermal break and double glazing capabilities sit available. As a result, commercial projects do not trade aesthetics for performance.
The Australian Glass and Window Association (AGWA) maintains independent technical guidance on window profile selection, glazing performance and Australian standards across residential and commercial applications.
How to Choose Window Profile Step 3: Specify Performance by Orientation and Site
Different orientations want different glazing. Specifically, north-facing rooms typically benefit from high SHGC double glazing for free winter solar warmth. By contrast, west-facing glazing usually wants lower SHGC and Low-E coating. Consequently, this manages summer afternoon heat. South-facing rooms see less direct sun. As a result, they may prioritise daylight and acoustic over solar control. East-facing windows generally tolerate moderate SHGC.
Site context layers further requirements. For example, bayside and coastal Melbourne sites need marine-grade powder-coat systems such as Dulux Alphatec for corrosion resistance. Furthermore, bushfire-affected fringes need AS 3959-compliant glazing assemblies up to BAL-FZ. Examples include Warrandyte, Eltham, Hurstbridge, and the Yarra Ranges. Additionally, inner-suburban heritage overlay sites often dictate sightlines and proportions. Equally, growth corridor volume builds prioritise cost-effective 7-star NatHERS compliance.
How to Choose Window Profile Step 4: Coordinate Finishes and Hardware
Finishes carry the design intent across the whole opening. Specifically, City Aluminium offers seven profile families. Furthermore, the complete Dulux Duralloy, Duratec, Alphatec, Pearl and Kinetic powder-coat ranges sit available. Additionally, Colorbond colour-matching integrates with roofing and cladding.
Hardware sits as part of the visual story. For instance, concealed multi-point locks and flush handles preserve clean lines on slim profiles. By contrast, statement hardware can become a design feature on heavier traditional profiles. Notably, our hardware catalogue spans entrance handles, lever handles, sliding handles, digital handles, mortice locks and window locks. Additionally, butt and concealed hinges plus specialist hardware sit available.
Why City Aluminium for Profile Selection
- Forty years of Melbourne fabrication — operating since 1986. Furthermore, we have the experience to match the right profile to the right opening across every build type.
- Local manufacture — we manufacture every product in our Melbourne facility. Consequently, custom sizes move through our process without imported lead-time risks.
- Architectural and Commercial range depth — from the Ultra Low-Profile Series and Designer Door Range to commercial-grade systems for shopfronts and multi-storey work.
- Twelve product types plus bespoke — every common window and door type in the catalogue. Furthermore, custom configurations come as standard.
- End-to-end One Stop service — manufacture, delivery, installation, retrofit and replacement. Additionally, supply-only sits available for builders.
- Specification collaboration — we work alongside architects, builders and homeowners through profile selection. Notably, we do not just supply off a catalogue.

Frequently Asked Questions
There is no single answer. Generally, premium new builds use a mix. For example, sliding doors and stackers handle the indoor-outdoor connection. Furthermore, awning windows ventilate kitchens and bathrooms. Additionally, fixed picture windows frame views. Likewise, double-hung windows suit traditional facades. Notably, the Architectural Range supports all of these in low profile, double-glazed configurations.
Usually, different openings have different functional and aesthetic requirements. As a result, a thoughtful project mixes profiles across rooms. By contrast, a single-profile choice often forces compromise somewhere. Typically, this lands on ventilation, sightlines, or budget.
The Architectural Range suits premium residential and architecturally designed projects. Specifically, slim sightlines and refined finishes carry the priorities. By contrast, the Commercial Range suits shopfronts, schools, multi-storey developments, hospitals and hospitality. Both ranges support thermal break and double glazing. However, the choice depends on durability, scale and security requirements.
Yes. Specifically, we walk through profile options with builders, architects and homeowners during specification. Furthermore, local manufacture out of our Melbourne facility means we can discuss custom configurations, finish samples and hardware combinations directly.
Lead times vary with project size and configuration complexity. 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.
Yes. Specifically, our One Stop service covers manufacture, delivery, installation, retrofit and replacement end-to-end. Furthermore, builders running their own installation crews can specify supply-only. In that case, delivery to site comes included.
