Now that the temperature outside has dropped, the windows start to accumulate water vapor. I am assuming that it might also lead to that black stuff forming. Is there a more efficient way of dealing with the condensate than wiping it dry every day?

    It doesn’t seem, that the movable part of the frame is even that cold. From the scale I’d estimate it at 17°C or so? It really seems that the contact between the frame and the pane is the weak point.

    For comparison, I’ve just gone and measured my relatively new windows, about 3 years old, plastic frame. Its -3°C outside as well.

    I’ve measured my pane temps by sticking a bit of matte tape to it:

    The pane is about 3°C colder than the ceiling and the floor:

    In my case, the coldest part is the fixed part of the frame:

    The contact area between the pane and the frame doesn’t cool off nearly as much as it does in your case. I guess, that’s your answer regarding the condensation. Not much you can do about that, it seems :/

    EDIT: Yeah, I think that is it. Just had a look at how the panes are fitted into my windows: The plastic frame overlaps them AND the pane edges aren’t metal or at least the metal is covered. In your case, the metal frame is isolated from the inside and the outside basically just by a bit of silicone. That’s probably what makes this heat bridge a lot less critical in my case.

      Thanks for the feedback! So, bad windows in my case. Either way, badly insulated windows just tend to form condensation it seems.

      I guess in the end it’s the usual: Regular short cross-venting and wiping off moisture - or go on an insane money spending spree on insulation and air conditioning.
