It's just like most of the time, a curse and a blessing at the same time :eek: Since these are 3.10m wide, floor-to-ceiling glass surfaces, they would have to be divided into three sections each, in order not to get doors that are too bulky. Then at least one part would remain as fixed glass anyway. Visually, I prefer the free glass surface of fixed glazing... but with the mentioned disadvantages. To avoid the problem of cleaning, all three parts should be openable, although we will have exclusively Venetian blinds and no shading on the windows/doors, which makes cleaning easier. At the old house, I had a huge lift-and-slide door and next to it a three-part casement solution with Venetian blinds in front of each. A fixed glass section would also remain with the lift-and-slide doors. Of course, a piece of furniture or something similar will partly be in the possible opening area of the doors, which doesn't exactly make the decision between practical and stylish easier for me. I am aware of the necessity of cross-ventilation, but getting experience values here also from owners of controlled residential ventilation systems is interesting for me, since it is new to me. Ideally, I would prefer 3 x folding windows on the south front to the garden/terrace, but then you have such a block standing to the side when opened. Hm... still searching for the holy grail... nothing has happened yet. But the topic of ventilation has already been somewhat clarified again.
