Types of windows: single-leaf, double-leaf, which widths - experiences?

No, the lower part is fixed at about 50 cm. It was approved that way. We were also in show houses where it was the same.

These are casement windows. The difference from 50 to 80/90 cm sill height must be realized through masonry; however, this is not approved by all building authorities. Some refer to a commentary which states that the required sill height must be created within the window itself. Rhineland greetings

Interesting, I didn't know that. Exactly, with us it is generated by masonry.

so you have 50cm of masonry and then a 40cm fixed window? but that is not floor-to-ceiling. besides, you could easily step onto the masonry (50cm) and then you only have 40cm of protection against falling (popular with small children). but I still don’t understand what the grid is for. a picture would be best.

I have no idea at all what you're talking about... I never said the windows are floor-to-ceiling, nor did I mention anything about bars.

a picture would be best.
