Hi,
I need some advice. In our house (3 years old, solid construction, 36.5cm (14 inches) Poroton blocks), there is mold forming in one room at the corner where two walls (both exterior walls) and the ceiling (upper floor under the flat roof) meet. There is no mold anywhere else in the house, and we ventilate the room daily.
I had the roofer check the site, and they removed the roof down to the concrete layer, but everything is dry there.
Now we’re really stuck... Everyone is puzzled. What could be causing this problem?
Thank you and best regards

Yes, it is a thermal bridge.
Once you have dried out the wall, it should improve. I don’t understand how this fits with your previously mentioned very good contribution. If a thermal bridge is present, simply drying out the wall once will only help temporarily. The thermal bridge must be eliminated.
If you revert to the old behavior, it only helps in the short term.
None of us knows how the thermal bridge was created. External corners, for example, notoriously tend to develop thermal bridges even with entirely correct construction. There is nothing more that can be done to eliminate them.

But who heats a bedroom above 19 degrees? It is often much cooler there. I don’t see a practical solution in that!We... We keep the entire house consistently at 22 degrees Celsius (72°F). We use thin duvets and keep the door open for fresh air. It’s wonderful for sleeping. If needed, the window can be opened.
