Advantages and Disadvantages: Raffstore or Roller Shutters?

If roller shutters have to stay up during strong wind, that's already a downside for us, as we often have storms and we frequently forget about things

Retracting during wind can be automated.

Venetian blinds are indeed more susceptible to wind, that is true, but shutters also must/should be raised during a real storm. At the latest when hail is added.

We also have two 2.60 wide venetian blinds! Nothing shakes or rattles at all, and the wind guard is included in the control system. In my opinion, such a system doesn't make sense without a proper control system anyway. Additionally, we were able to run some lighting controls through the control system.
We are here on a very windy mountain. The venetian blinds would go up starting at 14m/s. That means it has to be really windy. This hasn't happened so far.
We have blinds at two windows; of course, you have to pay attention to matching colors. However, they don’t offer any burglary protection either. A strong person could probably "move" them somehow.
Since venetian blinds must be planned very early if they are not supposed to be visible from the outside when raised, we decided against them at four windows back then for cost reasons. At that time, we still felt we could save money somewhere :P
That was actually the only (so far encountered) mistake: today, all windows would have venetian blinds. These things are simply great!
You can shade the interior without it immediately becoming dark inside the house. Why make great, large window surfaces only to always pull down a blind? I find that totally oppressive!
So: from my side, a clear YES to venetian blinds (even though they are more expensive than blinds) in combination with a proper control system. Warema units with Climatronic are installed here. The whole system also runs via app on the phone. Perfect for us!

We have blinds everywhere and would definitely do it that way again. I used to also sleep with roller shutters, but when you have children that changes, because you don't want to wake up with sore skin^^ And when we are tired, we also sleep even if it’s not pitch dark at night, aside from the fact that with z-lamellae you can also make it even darker.

For aesthetic reasons, we decided against the Z-slat and chose the S-slat. In my opinion, it also makes it dark enough!

I am someone who initially had roller shutters offered throughout the house by the window manufacturer. On the ground floor, we have 2 patio doors/windows measuring 2.33m x 3m on the south side and 2 patio doors on the west side measuring 2.33m x 1.76m. But when I saw last summer that all the neighbors had their roller shutters permanently down, the decision was easy. At least for these 4 openings, we had to have venetian blinds. However, since the budget is naturally limited and we like to sleep in complete darkness, roller shutters remained on the upper floor. Unfortunately, the color selection is problematic if you don’t take an aluminum roller shutter cover, because then the only venetian blind color option if you want everything to be homogeneous is white-aluminum.

My window manufacturer said that aluminum covers are three times more expensive than conventional roller shutters, but then you can also get RAL7016, DB703 or gray-aluminum.

For summer, I can actually only recommend venetian blinds on the ground floor for south or west orientation, unless you want to live like a madman (said ironically) or turn the light on when the roller shutters are down.

I wouldn’t worry about burglary protection with suitable RC2 or RC2N windows.
