Choosing materials for high moisture levels
In sauna, spa and wellness areas, moisture resistance is more important than in a typical living space. Hydro is therefore usually the first material we assess from a technical perspective.
Ventilation and temperature remain key considerations
Shutters must not block ventilation openings, opening windows or air circulation. The installation location is determined in relation to heat sources and condensation zones.
Privacy with adjustable daylight
The louvres can reduce overlooking while allowing the room to remain open to daylight.
Short answer
The essentials at a glance
In a humid room, it is not just the colour that needs to be right. The material, ventilation, distance from water and accessibility of the window all determine whether the shutters remain durable and practical.
Practical: Have moisture exposure, ventilation and window function assessed on site. This ensures that the material and installation are selected together to suit the room.
The choices that make the difference
Four points to assess before requesting a quotation
Moisture exposure
A bathroom next to a shower requires a different assessment from a well-ventilated kitchen or a dry toilet room.
Material choice
DeVo Hydro was developed for moisture-resistant applications and has an aluminium core for added stability.
Ventilation and window function
The tilt position, ventilation grille and window handle must remain accessible after installation.
Cleaning and use
Louvres and frames should be easy to wipe clean without harsh products or excessive water.
Avoid disappointment
Common mistakes when buying shutters
- Treating every bathroom as the same environment
- Forgetting about ventilation behind closed panels
- Choosing the material based on appearance alone
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 are moisture and ventilation taken into account?
Distance from water, condensation, ventilation, cleaning and window use are assessed in advance. In humid conditions, DeVo Hydro may be the appropriate material choice.
Is the same solution suitable for every window or room?
No. Moisture-resistant solutions for saunas, spas and pool areas. The window type, dimensions, installation position, demands placed on the material 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.
