Choosing aluminium windows requires several connected decisions: frame system, opening style, glass, colour, hardware, screens and installation. Selecting one feature in isolation can create a window that looks suitable on paper but does not match the energy report, opening size or way the room is used.
This practical guide explains what Melbourne homeowners and builders should confirm before approving a quotation or window schedule.
Standard or Thermally Broken Aluminium
Standard aluminium is durable, slim and practical for many residential projects. Thermally broken aluminium includes an insulating section between the internal and external profiles, reducing direct heat transfer through the frame.
The appropriate system depends on the energy report, design, window sizes, glazing, budget and performance goals. Compare JL aluminium windows and doors with our Thermal window and door systems.
Select the Opening Style
Fixed, awning, sliding, casement and tilt-and-turn windows provide different ventilation and clearance. Consider flyscreens, curtains, furniture, cleaning access and whether the sash can project safely inside or outside.
Our aluminium window opening style guide compares the main options.
Confirm the Complete Glass Specification
Do not approve a quotation that states only “clear glass” or “double glazing” where a more complete specification is required. Confirm pane thicknesses, cavity, Low E coating, tint, obscure glass and any laminated or toughened safety glass.
Glass thickness and makeup must suit panel dimensions, location and the selected aluminium system. See how to choose window glass and our double-glazed windows page.
Frame Colour and Architectural Style
Powder-coated aluminium colours should coordinate with roofing, cladding, brickwork, internal finishes and nearby doors. Dark colours can create stronger visual lines, while lighter colours may produce a softer appearance. Check the selected colour name and finish on the quotation rather than relying only on a screen image.
Decorative options such as colonial bars and glazing bars should be shown on elevations or approved drawings so bar positions align across windows and doors.
Hardware, Locks and Flyscreens
Handles, locks, rollers, hinges, operators and flyscreens must be compatible with the selected system and panel size. Confirm colour, operation and quantity. Large or heavy sashes may require different hardware from smaller residential windows.
Window Sizes and Configuration
Overall dimensions do not describe the complete window. The schedule should show fixed and opening panels, mullions, transoms, opening direction and any coupled frames. Large panels require review of glass, wind requirements, frame capacity and transport or installation access.
New Builds and Replacement Windows
New-build windows are generally coordinated with architectural plans and construction details. Replacement windows require assessment of existing openings, reveals, wall condition, flashing, access and surrounding finishes. Clarify who is responsible for measurement, removal, disposal and making good.
