Possibility to open windows with controlled residential ventilation - planning ideas

I find the controlled residential ventilation very good and would not want to do without it anymore. But I have a fixed window and the part of the sliding door that is fixed, and these are exactly 2 fixed elements too many.

Controlled residential ventilation reduces the reasons to ventilate, but something is missing. I do not want to miss the smell after the rain, the air in spring, the feeling of freedom that the open window wants to convey.

And the windows are easier to clean.

I understand you! In the end, there will always be one part that is fixed, unless you use exclusively the folding version for it. Do you happen to have a picture of your "fixed version" that you describe? I read that you would do this differently now, controlled residential ventilation or not, right?

I have controlled residential ventilation and I think it's great, never without again! As I said, there are reasons why window ventilation is still useful when needed. And in the end, 2 small holes are enough if they generate a draft. Air exchange does not only occur through as much open area as possible, but through airflow over opposite openings.

As a window solution, I'll throw Solarlux into the mix. You can open it completely, and nothing solid remains standing. In suitable weather, you then have 9m open and your living space practically outside. We love it.

Yes thanks, I already made some calls today regarding such folding doors. With 3.07m I should probably have 4 parts, according to what was said, although that would be too much material around it for my taste. For us it’s more of a hybrid anyway, we handle some areas ourselves, but windows are by the construction company or general contractor, although our supplier is not a typical GC in the often described sense here. I’m considering whether to do this one 3.07m window in the middle, in front of the dining table, as a folding door of some sort and have the other two "blocks" done more in the standard mode with one hinged door each, which alone would be sufficient in terms of usability (kitchen + small living room). At the other two windows it might be tight inside with the then pushed-aside stack of window panels. I also looked at some pictures of yours today; the folding windows open outward or inward and all in one direction, so basically like an accordion in one piece, right? And you fitted a whole area, that is one window block, with those and took the remaining windows from elsewhere? Somehow I feel that although that would be stylish, there might be a problem I’m not thinking of right now. I’m attaching a picture of this area with the three equally sized window blocks on the south side facing the terrace. Middle as mentioned would be dining, left mini fireplace reading area and right kitchen (still somewhat flexible). I would be glad if you could answer this and maybe you have an idea especially regarding our arrangement concerning windows/folding windows or similar. The currently recorded -fixed- was only the idea so far.

I understand you!
In the end, a part will always be -fixed-, unless you use the folding version exclusively for that.
Do you have any picture of your "fixed version" that you describe?

That's what I would do. The folding version instead of the lift-and-slide door
and the other simply to open instead of fixed.

I just imagine how wonderful it would be to open it completely. Behind it is the dining area.
