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!

Retlaw

What is that? Could you please briefly describe it?

If it is a completely fixed element, then that is not a problem. However, if the window can be opened (with a key or similar), then it is equivalent to a normally operable window. It sounds strange, but that is the case.

By keeping windows locked and discarding the keys, I actually prevent misuse more effectively than someone with a window that can be opened starting 40cm (16 inches) above the floor, or someone who still allows a tilt function.

Try explaining that to your contact at the building authority. 😉

The tilt lock allows you to tilt the window when it is locked. For example, to clean the window, you can unlock it using a key at the lower frame to fully open it.

In multi-family houses, for example, it’s quite common. It looks like this (I quickly took a photo of the hallway in my current building):

White window frame with two sashes and textured glass; green jade plant in the foreground.

Ah! I see! But I can’t apply THIS system to my plan, can I? Your windows have a transom.
