I would then choose a fixed panel over the full height and a door with a fixed panel above. And the door with a flat threshold.
Thanks also for the pictures. That is exactly the idea of our planner. But I wanted to inquire about further options, especially pure swing doors without tilt function. However, that seems to be something quite rare.
What material should the windows be made of? We have almost 3m high terrace doors with tilt and turn made of aluminum. In my opinion a total malfunction, because they are much too heavy and hard to operate and not properly adjustable. Therefore, I can understand the arguments of your window maker.
The material would probably be plastic, but that is not yet decided. We wanted to decide that in connection with the costs and the technical feasibility. The experience that 3m high tilt and turn doors are pointless is already very helpful. So would you prefer the variant suggested by Niloa (a fixed element above the door) or sliding doors, or would you forgo the tilt function? Thanks to you all in advance, it helps us a lot!
