ᐅ Condensation on windows, mold, thermal bridging. Are the windows poorly insulated?

Hello everyone,

There are periods, especially in winter when it’s really cold, when our windows sweat heavily from the inside. Additionally, despite airing out and sufficient heating, mold develops on the exterior wall where there is a thermal bridge.

On one hand, this obviously happens because the radiators are located far from the exterior wall. On the other hand, I would like to know how well—or of course how poorly—the wall is insulated, or if it is unacceptably poorly insulated. The only thing I was able to do is the lighter test. Please have a look at the linked video.

Thank you!

So what am I doing wrong?
And what was the temperature at the exterior wall/window? If there is moisture present, the surface must be cold enough.

Are you starting a new thread every time you don’t like the answers? Your heating and ventilation habits don’t match your apartment.

So either change your behavior or move out...

Heat more and ventilate accordingly. If you don’t want to do that, then look for a new apartment.

Addendum, since you are being unwilling to see reason: If you simply continue like this, even though the landlord has already told you what is necessary (more ventilation and heating), then you will be liable to compensate him for damages.
