Windows & window size: what to choose? Double-leaf windows?

Hello,

we have partially planned 3 windows for our bungalow measuring 138.5 x 126 high and one measuring 138.5 x 76 high. With this width, maybe one should take double-wing windows? Do they even exist?

Since we have not planned a controlled residential ventilation system, we will ventilate more often, so relatively wide windows (single-wing) will be opened into the room when ventilating, which I find disturbing; over time, it can also sag a bit (weight and long lever), and if you have a flower vase or something else on the windowsill, you have to completely clear it when ventilating, whereas with double-wing windows you can slide it to the side.

Thanks for your tips

There is everything... everything is custom-made anyway. I wouldn't choose single-pane for such wide windows either, but with two panes the window area becomes quite small, 1.50 m in width would be better, it also looks less square.

Best regards
Sabine

Hi, why did you decide against ventilation? Have you thought it through carefully?

more because of the costs of such systems.

As a supplement, I add the following data:

I consider "Golgend" to be a very beautiful word
