External aluminium sliding screens give architects a flexible way to manage privacy, views and external shading without fixing the façade in one position.
Their biggest strength is positional control. You can move the screen across glazing when privacy or shade is needed, then slide it away to open up the view. But that flexibility has limits when a project needs responsive, hour-by-hour solar control.
This guide explains where our aluminium sliding screens work best, how they compare with operable louvres, and what to consider when specifying them.
Sliding screens are best suited to projects where privacy, architectural screening and movable shade are the priority. They can reduce direct sunlight reaching glazing, but most sliding screens provide fixed shading once the panel is in position.
Where more responsive solar control is required, operable louvres may be the better option.
Yes. External aluminium sliding screens can provide effective shade by intercepting direct sunlight before it reaches the glazing.
The important distinction is that their adjustability is mainly positional. You move the entire panel across or away from the opening rather than continually changing the shading angle throughout the day.
This makes sliding screens particularly useful where a project needs a combination of privacy, screening, views and movable shade.
Australian Government passive design guidance also supports the principle of stopping direct solar radiation before it reaches the glazing.
Sliding screens and operable louvres both provide external shading, but they control it differently.

Neither system is automatically better. The right choice depends on what the façade needs to achieve.
Sliding screens are a strong choice when privacy, screening and flexible control over views are the main priorities.
Panels move horizontally along a track, so they can be positioned in front of exposed glazing when shade or privacy is required, then moved away when you want more daylight or an uninterrupted view.
They work particularly well around:
Aluminium is also well suited to external applications. It does not warp like timber and can be finished in powder-coated, anodised or woodgrain options to suit the wider architectural design.
A standard sliding screen allows you to change the position of the screen, but not the shading density of a fixed infill.
If a panel uses fixed louvre blades, for example, the blade angle and spacing determine how much light, privacy and shade the panel provides. Sliding the panel changes where that shading occurs, but the blade geometry stays the same.
The same applies to perforated sheet and swaged grating. Their screening density is selected during specification rather than continually adjusted after installation.
This is why sliding screens work particularly well for privacy and movable screening, but may not provide the same dynamic solar control as operable louvres.
We can configure our sliding screens with different infills depending on the project's privacy, airflow, shading and aesthetic requirements.
Aluminium louvres provide consistent screening and shade. Blade angle and spacing can be selected around the performance and appearance required.
For projects where the screen itself does not need to move, we also offer dedicated fixed louvre systems.
Manually operable louvres can also be incorporated into a sliding panel, giving you control over both the screen position and the blade angle.
This can provide greater flexibility, although panel spacing and movement need to be considered carefully during specification.
Perforated sheet and aluminium swaged grating provide alternative architectural screening options.
Both create a consistent level of privacy and screening, with the selected pattern or profile determining how much visibility and light passes through the panel.
Start by defining what the screen needs to achieve. Privacy, shade, view control, ventilation and architectural appearance can all influence the final configuration.
Orientation matters because different façades experience sunlight differently.
East- and west-facing glazing can be particularly challenging because of low-angle morning and afternoon sun. North-facing glazing generally receives higher-angle summer sun, which can often be addressed with appropriately designed horizontal or adjustable shading.
If responsive solar control is the main objective, an operable louvre system may be more suitable than relying on a fixed-infill sliding screen.
The size and weight of the panel affect the hardware and support structure required.
Our sliding-screen documentation includes top-hung and bottom-rolling configurations, with system limits that need to be checked against the selected screen design.
This is best resolved early rather than after the façade and surrounding structure have already been detailed.
Track position, fixing substrate, waterproofing and cladding interfaces should be coordinated during design development.
We provide product and fixing details to help architects integrate the system with the surrounding structure.
Sliding screens can be manually operated or motorised.
Where motorisation or home automation is required, power and control requirements should be coordinated early so the necessary cabling can be incorporated before linings and cladding are completed.
External screens need to be designed around the conditions they will experience, including their size, support structure and project-specific loads.
We provide technical drawings, fixing details, CAD/DWG files and other specification information through our architectural resources.
Sliding screens are an effective option when you want to combine privacy, movable screening and architectural flexibility.
Where the project needs more responsive control over solar heat gain and airflow, operable louvres may be more appropriate. On some projects, the best solution is to use both systems in different parts of the façade according to orientation and performance requirements.
The important part is deciding what each section of the façade needs to do before selecting the system.
