ᐅ Floor-to-ceiling windows on the upper floor without a parapet or knee wall

Hello everyone!

I have been following the forum for a while, but now I have some current questions that I haven’t found answers to yet, so I have become a more active member.
I would like to avoid using guard rails on the lower edge of floor-to-ceiling windows upstairs to eliminate the risk of falling from the window sill.
Therefore, I plan to implement the following alternative measures:

1. Use safety glass corresponding to category A *

2. Lockable with a key, with the key stored elsewhere

3. Visible indicators on the window such as blinds or frosted glass stickers

4. Restrict access by placing furniture or plants in front of the windows

Has anyone here already received official building approval for something like this?

I would also be willing to remove the window handles if it came down to it.

For those who haven’t figured it out yet—I’m not a fan of French balconies, transoms, or divided windows.

Perhaps someone has done something similar with windows that are basically fixed?

Thank you for sharing your experience!

40 cm (16 inches) parapet? That must be questioned!

You’re welcome to do so. However, there will still be a fixed panel of about 50 cm (20 inches), which is much better when it comes to plastering. (We specifically discussed this in advance with the building authority.)

So we are looking at a “parapet height” (fall protection) of 90 cm (35 inches). Then state it clearly and correctly right away!

Then there are always problems with cleaning, right? You can’t clean the roller shutters anymore either. No matter how often it’s necessary.

It’s not impossible. There are special tools with magnets (slider on the outside, sponge on the inside) that still allow you to clean roller shutters from the inside (if anyone ever actually does that).

Parapet = brickwork 🙄

Yes, Master :p

When it comes to aesthetics: There are venetian blind systems that integrate an almost invisible (glass pane) as a fall protection.

That’s exactly how we have it. Maybe I used the term French balcony incorrectly for this. The glass pane is installed within the window frame and is almost invisible. When the venetian blinds or roller shutters are closed, they cover it completely, so it is not visible from the outside at all.

Do you always lie on the floor to look out the window?

😀 Not always, but from the upper floor I like to look down into the garden at an angle.
Or to put it another way: seeing some of the crossbars doesn’t really offer any ADVANTAGE. At least not for me. Pigeons or similar creatures probably think quite differently about it.

The tip about cleaning the blinds is really valuable. I hadn’t thought about that at all! Even though I already have a blind that I can’t clean from the inside, which is incredibly annoying with all the squashed insects stuck in it.
