Dear forum community,
I would like to ask for a brief assessment regarding window options.
It concerns the windows in the children’s rooms. These are the second windows, meaning there is also a floor-to-ceiling window on the gable side.
The windows in question (with blinds) are located on the eaves side (south side) in the knee wall area (finished interior height 1.80 meters (5 ft 11 in)) and are currently planned to measure 2 m x 70 cm (height x width 72 cm (28 in)). It is known that fall protection will be required. The children’s rooms are 15 square meters (161 sq ft), so natural light is more than sufficient.
However, we are no longer sure whether 2 meters (6 ft 7 in) is too wide. We are now leaning towards a width of 1.76 m (5 ft 9 in). The windows are not tall, which might compensate for the width.
Now the question is, would tilt-and-turn (French) windows without a mullion be better for increased daylight, or should we choose windows with a central mullion? There is no need for load-bearing capacity through the window.
Has anyone installed similar windows and can share their experiences? How does the daylight performance actually compare between these two options?
Thank you for your assessments and opinions.

I meant: leave the bottom hinged as usual and unhook the top sash to switch from tilt opening to full opening.
...I also meant that: however, the window needs to be supported, which is not easy... and we only have double glazing.
And don’t tell me that the window with the unhooked top sash doesn’t need support, because I would never want to test that myself [emoji23]
If I had known that, we wouldn’t have chosen them!
I imagine the space arranged so that a desk is placed below the window (the sill height fits this). The top edge of the window, with the handle in the middle, is roughly at the housewife’s shoulder height. When opened and tilted downwards, the window with its handle rests on the desktop. This is much less strenuous than when the top edge of the window is above head height and the bottom edge above shoulder height over the bed, as is the case in some bedrooms. The perceived weight always depends on the relative heights between the center of gravity and the person applying the force.

Knallkörper10 Feb 2017 20:24We have tilt-and-turn windows without a mullion at the top and with a mullion at the bottom. The increased daylight performance of tilt-and-turn windows without a mullion is certainly measurable but, in my opinion, not necessarily decisive. Windows with a central mullion offer better resistance against driving rain, but since you have roller shutters, that should protect you from rain. Another advantage of tilt-and-turn windows without a mullion is that you might be able to bring in a sofa with a crane at some point.
However, I also tend to prefer the tilt-only window design.

Hello,
thanks for the many contributions. We have now decided on windows with a central mullion and reduced the width from 200 to 173cm (79 inches). From the outside, they still look the same—so no noticeable difference.
By the way, the windows were "slightly" more expensive compared to sliding windows without a mullion, but the extra cost was waived due to the small difference.
I’m now looking forward to the result....
