ᐅ Roller shutters or blinds on the ground floor

The wind sensor can be adjusted; you just need to check the manufacturer’s specifications.

Isn’t it possible to adjust that? And are rail-guided systems any different?

Well, let me start from the beginning:

In general, it is NOT the case that venetian blinds automatically move up. You can control the blinds with a motor just like you would with roller shutters. BUT: The big disadvantage of venetian blinds is their weight, which makes them very susceptible to wind. A normal roller shutter has its own weight but is far less vulnerable. As mentioned, the individual slats of the venetian blinds can rattle, and more importantly: the slats can jump out of their guides, tangle, bend, and so on. This can also happen with rail-guided venetian blinds—we’ve experienced it all. To prevent this, there are so-called sun/wind sensors. These sensors are optional, but for venetian blinds that are meant to last, they are practically mandatory. These sensors measure sunlight, wind direction, and wind speed (so-called astro functions) and then control the blinds accordingly. Therefore, manufacturers recommend placing one sensor on each side of the house. Personally, I think that is overkill; in my opinion, placing one sensor on two opposite corners of the house is sufficient. One sensor on the sunrise side and one on the sunset side covers everything. The sunlight response of the sensors can be deactivated, but the wind control is always active. At least, I am not aware of any major venetian blind manufacturer where this works differently. The sensors come as wired versions or with solar power, and the control of the individual venetian blind motors is then done wirelessly.

Why are the sensors optional but recommended? Imagine you have the slats down and go shopping, to work, or somewhere else. While you’re away, the wind picks up, your slats tangle and bend, and you come home to expensive repairs, having to replace individual slats. It’s no fun for a product that costs several hundred euros. The window installer will not cover the costs in this case, as it is not covered by warranty.

Of course, it varies from region to region. In some places, the automatic wind control will activate once a month, in others maybe once a year.

Here comes my point about durability again.

I’m spending a lot of money on this, and during severe weather, the chance that an external venetian blind breaks is significantly higher, right? That also makes me somewhat hesitant. I honestly find it a joke that I would have to pay only 1€ more for it—considering the effort and materials, it’s hardly even close to being as expensive as a roller shutter.

Oh, and another disadvantage I just thought of: cleaning a roller shutter is definitely easier, correct?

I would overlook that. There are venetian blinds with nano coating, highly weather-resistant coatings, etc. They’re pretty much the same—it just costs extra, of course.

It’s quite simple: if you want shading, light control, and the ability to see outside, choose venetian blinds. Otherwise, go for roller shutters. Both systems are mature and practical. We have neither.
