This is the answer to the question Can I open the windows while the screed is drying?
Revision 1
The cement screed should reach equilibrium moisture after 5 weeks. This will cause a significant amount of water to accumulate in your home, which will cause the insulation to shine through, such as in the ceiling/roof structure if it is already installed. It should dry as quickly as possible.
You need to install 2-3 condensate dryers, run them for a few days and empty them daily until a maximum relative humidity of 55%-60% is reached.
Tilting the windows is not enough; the amount of precipitation must also be taken into account. Last year, a construction site had wet drywall damage this way because the windows on the weather side, which were tilted by the builder, received a lot of rain overnight.
