Aluminium exterior shutters combine the look of traditional shutters with adjustable louvres and a material chosen for outdoor use. The façade, fixing method and window function are at least as important as the colour and louvre size.
Outdoor applications require a different technical assessment
An outdoor application is exposed to rain, temperature fluctuations and wind loads. Panel dimensions, hinge points, locking mechanisms and the fixing substrate are therefore assessed as one structure. An interior solution cannot simply be transferred to the façade.
Control light from the outside
Adjustable louvres can control direct sunlight and privacy before the light enters the home. The exact effect depends on the louvre position, the façade orientation and the distance between the shutter and the window.
Coordinating the colour with the façade and window frames
Black can create a striking contrast against brickwork or a light façade, while white creates a calmer look alongside light-coloured window frames. The coating and colour should be assessed in daylight next to the brickwork, roofline, window profiles and other exterior details.
Projects in Arendonk
In Arendonk, DeVo installed black aluminium exterior shutters with 89 mm louvres across windows of various sizes. The same design was repeated around the home, giving the shutters a cohesive appearance despite the differing dimensions.
Measuring from the outside
Window sills, roller shutter boxes, rainwater drainage, solar shading and projecting façade details can affect the opening. That is why we measure not only the window, but also the clearance needed for each shutter to move freely on the façade.
Short answer
The essentials at a glance
The material determines the appearance, weight, maintenance requirements and suitability for the room. The best choice depends on the load and the desired atmosphere, not just on a photograph.
Practical: Assess material samples in daylight and in the actual room. Texture, maintenance and stability can vary significantly between collections.
The choices that make the difference
Four points to assess before requesting a quotation
Texture and colour
Oak, Basswood, Pinewood, Ashwood, Hydro and aluminium each respond differently to light and finishes.
Room and load
Humidity, sunlight, intensive use and panel size can influence the choice of material.
Maintenance
Smooth material is cleaned differently from a tactile wood grain or natural oak surface.
Panel size and engineering
Weight and stability determine which dimensions, hinges and operating systems are appropriate.
Avoid disappointment
Common mistakes when buying shutters
- Choosing the material based on price alone
- Assessing a small sample as if it were the entire window
- Forgetting about maintenance and moisture exposure
From idea to installation
How a carefully managed made-to-measure process works
- Collect photos and approximate measurements of the windows.
- Compare material, colour, louvre size and operation.
- Have every window professionally measured at multiple points.
- Confirm the panel layout, technical details, price and schedule.
- Have your shutters installed, adjusted and explained to you.

Frequently asked questions
Are aluminium exterior shutters the same as interior shutters?
No. Exterior shutters are installed on the façade and must take account of outdoor loads, fixings, window details and maintenance. They are therefore assessed as a separate made-to-measure project.
Can the louvres of aluminium exterior shutters be adjusted?
With a suitable design, the louvres can be adjusted to control light and privacy. The exact operation depends on the dimensions, panel layout and installation.
What colours are available for aluminium exterior shutters?
The available colours depend on the current aluminium collection and coating. During the consultation, samples are assessed alongside the façade, window frames and other exterior details.
Is the same solution suitable for every window or room?
No. Made-to-measure exterior shutters with adjustable louvres for façades, light control and a durable outdoor solution. The window type, dimensions, installation position, material loads and everyday use are assessed for each situation.
What does DeVo check during the professional site survey?
We take measurements at multiple points and check the frame, reveal, handles, opening direction, windowsill, available panel clearance, and the desired louvre and panel configuration, among other details.
How do louvre size and panel configuration affect the result?
They determine how many lines you see, how open the view through is and how practically the panels can open. The proportions in relation to the window matter more than one standard size.
Can I compare materials, colours and operating options first?
Yes. During your consultation and in the Oud-Turnhout showroom, you can compare current collections, colour samples, louvre sizes and operating options side by side.
