It's no different for now: outdoor blinds are still not really breaking through in the Netherlands and Belgium. They are there, of course, but not en masse. You see them more in Germany, but less in the Low Countries. We are more of the screens. Still, outdoor blinds can be a very suitable solution in certain situations.
Suppose the main sleeping quarters in the house have windows facing east. The occupants naturally want to air those rooms, but then the sun shines in first thing in the morning. With the strength of the sun we had in June, a lot of heat comes in right away. Closing the shutters is not an option, because although the sun is kept out, the airing is also finished. Screens do let air through and they block the sun, but ventilation is still limited. No, then outdoor blinds! By tilting the slats, the sun is blocked extremely effectively, but still (fresh) outside air can enter unrestricted. The ability to block the sun and ventilate combined in one product. Could it be more convenient!
And technically, the exterior blinds from the leading providers on the market are also getting better and better. Improved guide systems combined with new, cleverly designed slats mean that exterior blinds are now more stable and rattle less or not at all. In addition, they seal better, providing a sealed layer of stagnant air in front of the window. As a result, in the cold seasons, they contribute to the window's insulation value - similar to shutters - which can help reduce heating costs.
An all the other benefits of outdoor blinds, of course, remain unchanged. Blocking out the sun without blocking out light, for example, reducing the need to resort to artificial lighting. And exterior blinds make one feel less confined because the view through to the outside is maintained. In fact, it's a mystery why everyone doesn't want outdoor blinds!
