Which window fittings are recommended - experiences?

Basically correct, but for windows on the 2nd and 3rd floors without a balcony – so 6-8m high – negligible ;)

That is completely correct. I had meant to say that more generally.

As always, the question of security depends not only on the window but also on whether the neighbor has easy access to his large ladder and the window is open ;)

Hi Thank you I will save the money if the quality is about the same. Because if someone wants to enter the house, it would be at the bottom and not at the top, which would be much more complicated. And since I have the 2/3 floor in the house, I can save it. Thank you
