Glass wall as wind protection - How high - How does wind behave?

Hello,

our terrace is somewhat exposed and elevated. Often, quite a strong wind blows through there.
On the main side from which the wind comes, there is a retaining wall, so a fall protection must be installed there anyway (so far only a provisional one is in place).

The idea now is to install a glass wall instead of a railing.
Ideally, we want to kill two birds with one stone: wind protection and safety.

Now the appearance comes into play. Especially since this wall is located in the line of sight into the distance from the living room. We don’t want to “block” the view more than necessary. Even though it is glass, the view is still somewhat restricted.

Therefore, the question is how high we should make this glass wall.
I estimate the minimum height for safety reasons is 90 cm.
Most elements have maximum heights of 180-200 cm. That would be too high for us visually, but probably the best option in terms of wind protection.
Now it gets more subtle: some elements come in 100, 120, 140, 150 cm (depending on the provider).
From an aesthetic point of view, 120 cm would certainly be a good solution, 140 cm would still be acceptable.

Before I jump to the premature conclusion of taking 140 as the apparently best compromise (as high shielding as possible with still acceptable appearance), I would like to know how wind behaves behind such a wall.

I’ve also heard that with a higher wall, the wind would swirl more strongly directly behind it and “fall down” heavily.

The seating furniture is located about 1-2 m away from the glass wall.

Could someone perhaps give an assessment?
- The higher, the better?
- How is it with these swirls?
- Doesn’t it all make no difference if it doesn’t become 2 m?

Thank you very much.

My fundamental view is already stated here: and here: . From a wall perpendicular to the wind - and without diffusers in front of it - I would expect nothing else than that it is flooded from the front and shaken thoroughly - and of course, also overflowed.

Get inspired by [Strandcafé-Lösungen] and take a tour with seat testing at various locations. Long weekend in the Netherlands on the North Sea - that should be next.

I don't have diffusers (in German Windbrecher) and I can't have them. Not in that spot.

We've already dealt with the beach cafés. They all have approximately 2m high glass walls and the tables right behind them. Tables in the 2nd or 3rd row get their own glass wall again.
There is a lot of wind by the sea but it's practically a constant condition.

How about a solution with a fixed glass module as low as possible and a movable one that folds over it when there is wind? Depending on the length to be spanned, that could work. Sitting without wind and looking without glass.

didn't even know that exists
need to find out how much something like that costs and if it’s also reliably stable, things that are movable tend to wear out
but if there is a reasonable solution, why not
