Aluminum-wood triple-glazed window with internal condensation despite the warm edge

...
But I have noticed another effect.
I found a window in my place that is fogged up on the lower half from the outside. The fogging can be wiped off, but it reappears after a short time. It only affects one pane out of 11 on this side of the building (east). And that at -5 to -15 degrees.
I am already pondering how to explain this.

Is the heating behavior in the room with the window different?

Is the heating behavior in this room different with the window?

No, about 21.5-22.0°C and the window has two sashes, only one is affected.

Are you now accepting the fogged-up windows? Unfortunately, I forgot to ask the carpenter who installed the windows when he was here again today because of the new front door. But I will still follow up on that. I have to call him tomorrow or the day after anyway. However, I assume that even today’s windows show certain weaknesses at significant subzero temperatures. The window is certainly still the coldest spot in the (modern) wall, isn’t it? And if there is increased humidity on top of that ...

Yes, we do not complain, we are not in the mood. Such cold nights only happen every few years and it also dries quickly by itself again.

The window is certainly still the coldest spot in the (modern) wall, right? Especially if there is increased humidity ...

That would also be my explanation. Even with triple glazing, one can assume that with temperature differences of 35 Kelvin (outside -15, inside +20), physics cannot be outsmarted.
