Louvre size sets the rhythm
Smaller louvres create more horizontal lines and a more refined look. Larger louvres appear calmer and provide a better view outside when open.
Consider window height and viewing distance
The ideal proportions depend on the scale of the window, the panel width and the distance from which you usually view it.
Compare the sizes in person
In the showroom, you can see 47, 63, 76 and 89 mm side by side. DeVo Aluminium features 89 mm louvres.
Short answer
The essentials at a glance
Technical details determine how calm the shutters look and how comfortably they work day to day. Operation, frame, hinges, louvres and panel layout must be designed together.
Practical: Have the window handle, opening direction, available depth and operating system checked together. These details determine whether the shutters work comfortably every day.
The choices that make the difference
Four points to assess before requesting a quotation
Operation
ClearView, Ultra ClearView and a tilter differ in visibility, feel and technical availability.
Frame
The window depth and installation position determine which frame provides the best fit.
Hinges and opening direction
The hardware must support the panel weight while allowing sufficient freedom of movement.
Splits and divider rails
Louvre sections can be operated separately when privacy and daylight require it.
Avoid disappointment
Common mistakes when buying shutters
- Consider the technical details after choosing the colour
- Forgetting window handles and opening angles
- Choosing an operating system that is not compatible with the collection
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
How can I assess this choice in my own interior?
View samples in daylight alongside the window frame, wall, floor and fixed furniture. A colour or proportion may look different on a small screen than across an entire window.
Is the same solution suitable for every window or room?
No. A spacious look and excellent visibility when the louvres are open. The window type, dimensions, installation position, material load 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.
Are measuring and installation included in the process?
Yes. DeVo guides the project from advice and technical measuring through to made-to-measure production, installation, adjustment and guidance on use and care.
