Proper drying / tilting the window?

Hi,

over 5 weeks ago we received our cement screed.
For almost 2.5 weeks now we have been diligently drying our house. The heating curve is now falling again.

Unfortunately, we can't get the moisture under control. Ventilating more than twice a day is impossible; in the first week we ourselves only managed once a day.

We are therefore still at 95%.

Now I wanted to ask how advisable it is to keep 2 opposite windows on each floor tilted.
Does that make sense or is it rather disadvantageous?

After 5 weeks, the cement screed should have reached its equilibrium moisture. In your house, considerable amounts of water will therefore be stored, which, for example, ensure illuminated insulation in the ceiling/roof structure if it has already been installed. It should dry out as quickly as possible.

Be sure to set up 2-3 condensate construction dryers, run them for several days, and empty them daily until a maximum relative humidity of 55%-60% is reached.

Tilted windows are by far not sufficient; in addition, rainfall must be taken into account. Last year, a moisture damage occurred on a construction site in this way because the windows tilted by the builder on the weather side were heavily rained on at night.

Yes, presumably. We want to put a few dryers in at the latest after priming the walls and the fine plaster on the interior walls. The controlled residential ventilation would also be optimal for drying, but we were told that it will only be activated at the end when no more construction dust is produced. But basically, airing through tilted windows at temperatures below 10 degrees is not harmful to the building fabric now, is it?

Tilt-and-turn windows do not provide significant air exchange and you get drafts at exposed spots. I would use the [Kontrollierte-Wohnraumlüftung] now - with appropriate filters in front and low speed.

Hello

I would keep the windows closed and set up dehumidifiers.
Either from the company for drying technology or rent from the construction machinery rental.
Everything else is not effective.

I would use controlled residential ventilation now - with appropriate filters in front and low fan speed.

Tilted windows then achieve a higher air exchange rate than controlled residential ventilation on a low setting with extra filters that prevent the airflow. Oh, I also think proper construction dryers are better avoided.
