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.

Komposthaufen10 Feb 2017 12:01The practical consideration of cleaning fixed glazing cannot be ignored.
Still, just as a thought: we have so many unusually sized windows that we have to hire a company to clean them. It’s not that expensive if you don’t do it monthly. I wouldn’t have thought to design a beautiful house based on how easy the windows are to clean.
Back to the topic: choose standard windows with a mullion. As far as I know, they are somewhat more common to manufacture and therefore possibly a bit cheaper, with a slightly more stable frame construction—and, as mentioned above, the sashes can be tilted independently of each other.

The windows in question (with roller blinds) are located on the eaves side (south side) in the knee wall area (finished interior height 1.80m (5 ft 11 in)) and are currently planned at dimensions of 2 m x 70 cm (width x height 72 cm (2 ft 4 in)) (it is known that fall protection is required). [...]

You can remove it from the hinges for cleaning, and it interferes less above a desk compared to having to clear space for fully opening it. For a secondary window, tilt-only should be completely sufficient. This could even make fall protection unnecessary (though I’m not fully familiar with the regulations). Regarding the window widths, I tend to avoid mixing many different sizes and lintel heights within one house. Therefore, I would also look at what other window sizes are being used elsewhere in the house before deciding.

Regarding window widths, I tend to avoid mixing multiple lintel widths in one house.You have to weigh this carefully: while you don’t need fall protection, cleaning can only be done safely with two people! We have a 70 x 150 cm (28 x 59 inches) window, and it’s quite heavy when detached.

Bieber081510 Feb 2017 13:21We had windows with a central mullion in the apartment and have now deliberately chosen French casement windows (to avoid the annoying mullion).
I wouldn’t want special solutions (tilt-only?), I would simply go for standard windows. Either with or without a mullion.

I wouldn’t want custom solutions (tilt only?), I would just go for standard windows. Either with or without a mullion.A mullion or no mullion basically just means a visual difference of a few centimeters (inches) of frame width in the middle. In my opinion, a horizontal layout looks more consistent and intentional if you don’t divide the width. Tilt-only isn’t a custom solution: it’s the same window with a slightly cheaper opening mechanism, nothing more. But unlike fixed glazing, it’s suitable for exterior cleaning without needing scaffolding.
A “normal” tilt-and-turn costs (a bit) more; I wouldn’t choose a solely turn-only window because at the installation height, it would swing out right over a table placed underneath.
