Aluminium Windows Melbourne
JL Windows supplies custom aluminium windows in Melbourne for homeowners, builders, new homes, renovations and window replacement projects. Our range is organised into three clear JL product families: Essential, Thermal and Thermal Plus. See how frames, glass, seals, drainage and hardware work together in our complete window and door system guide.
Choose the JL Series That Fits the Project
Essential Series
Practical aluminium systems for everyday residential projects.
A strong starting point for standard new homes, renovations and replacement projects where durable aluminium frames, straightforward operation and value are the main priorities.
Typical configurations include sliding, awning, fixed and combination windows.
Thermal Series
Thermally broken aluminium for stronger whole-window performance.
Designed for projects requiring improved thermal separation through the frame and broader performance options. Thermal Series can be paired with suitable double glazing and Low-E glass according to the project requirements.
Available configurations include awning, sliding, casement, tilt-and-turn and fixed windows.
Thermal Plus Series
Higher-specification options for demanding architectural and energy-performance briefs.
Thermal Plus sits above the core Thermal range where the project calls for a more advanced frame and glazing package, larger or more demanding openings, or stronger performance targets.
Final configuration and performance depend on the selected product, glass, size and project documentation.

Window Styles
JL window configurations include sliding windows, awning windows, casement windows, tilt-and-turn windows, fixed windows and combination windows. Not every style is available in every series, and final suitability depends on opening size, glass, performance requirements and the project design.
Performance & Glazing
Series selection is only one part of the specification. Whole-window performance also depends on the glass, opening type, size, seals and installation. Review JL whole-window U-value and SHGC data, AS 2047 performance information and the glass selection guide.
Planning & Cost Guides
Before requesting a project quote, compare the main aluminium window cost factors in Melbourne, including opening style, size, glazing, frame system, hardware and installation scope.
Which Series Do I Need?
You do not need to choose the series before requesting a quotation. Send the project plans, energy report or replacement requirements and JL can compare suitable options against the brief.

For builder projects, JL can review plans, window schedules, glazing requirements and installation scope before quotation. Send plans for project review.
