Different types of aluminium windows provide different ventilation, views, cleaning access and hardware requirements. The best opening style depends on the room, window size, building design, weather exposure and the way people use the space.
JL Windows supplies custom fixed, awning, sliding, casement and tilt-and-turn aluminium windows for compatible Melbourne projects. This guide explains the main differences without assuming one style is suitable for every opening.

Fixed Aluminium Windows
A fixed window does not open. It provides daylight and views with fewer moving components than an operable window. Fixed panels can be used alone or combined with awning, casement or other opening sections.
- Useful for: views, feature glazing and areas where ventilation is provided elsewhere.
- Consider: external cleaning access, solar exposure, privacy and required glass type.
Awning Windows
An awning window is hinged at the top and opens outward from the bottom. It can provide controlled ventilation while the sash remains outside the room. Opening size, wind exposure, hardware capacity and access must be reviewed for each panel.

Sliding Windows
A sliding window uses one or more sashes that move horizontally along tracks. Because the sash does not project into or outside the room, sliding windows can suit areas beside paths, decks, balconies and internal furniture.
- Useful for: practical ventilation and openings where projecting sashes are unsuitable.
- Consider: the portion of the opening available for ventilation, track cleaning, rollers, locks and flyscreens.
See our Essential sliding windows and Thermal sliding windows.
Casement Windows
A casement window is hinged on the side and opens like a door. Depending on the design and hardware, it can provide a wide opening and direct airflow into the room. The opening direction and clearance must be coordinated with paths, screens, curtains and surrounding architecture.
Panel size, wind conditions, hardware and any opening restrictions need assessment. Learn more about thermally broken casement windows.
Tilt-and-Turn Windows
A tilt-and-turn window can tilt inward at the top for ventilation or open inward from the side for a larger opening, subject to the handle position and selected system. This flexibility can support ventilation and internal cleaning access.
- Useful for: projects seeking two opening functions in one sash.
- Consider: internal swing clearance, curtains, furniture, handle operation and the required opening restriction.

Combination Windows
Large openings can combine fixed and operable sections. For example, a fixed centre panel may be paired with awning or casement windows, or a wide opening may use several sliding panels. The divisions should balance ventilation, views, structural requirements and the building elevation.
Choosing the Right Window Opening Style
- Identify the required ventilation and preferred clear opening.
- Check whether the sash can project safely inside or outside.
- Consider flyscreens, curtains, blinds and nearby furniture.
- Review cleaning access, particularly for upper levels.
- Confirm panel dimensions, wind requirements and hardware limits.
- Choose compatible single or double glazing.
- Coordinate any opening restrictions required by the project.
