Hello
I have another question for you.
Our solid construction house (basement, ground floor, attic – 270m2 (2900 sq ft)) will be plastered inside next week. After that, the floor insulation will be installed, followed by the screed (anhydrite). Unfortunately, there were delays in the construction process, which now means that the roof will only be insulated and fitted with a vapor barrier after plastering and screed work.
I am concerned that the roof structure will accumulate moisture and won’t dry in time before winter to allow the insulation and vapor barrier to be installed properly.
Therefore, I would like to start using a construction dryer early to help dry the roof structure and protect the wooden windows somewhat.
Of course, as always, everyone involved in the construction has a different opinion...
Screed installer: Not necessary, it damages the screed while curing.
Design office: Great idea, do it. By the way, we rent them out at a reasonable price.
Neighbor: We had huge problems with mold on the wood.
Acquaintance: No problem, just ventilate thoroughly.
And so on.
So, my questions to you as outsiders:
Should I use a construction dryer, yes or no?
Should it be used right after plastering or only after the screed?
One per floor?
Additional fans?
What relative humidity should be maintained?
What capacity/performance should the devices have?

A few details would be helpful.
Do you have a concrete ceiling or a wooden ceiling?
How is the roof insulated?
A few weeks ago, I looked into this topic because we have a concrete ceiling and a cold roof.
So, on top of the concrete ceiling, there is a vapor barrier (which is a thick foil), then styrofoam insulation, and finally OSB boards.
As far as I understand, the vapor barrier is only needed to prevent moisture from gradually penetrating into the styrofoam and getting trapped there.
So, if you have a concrete ceiling with no insulation above, it doesn’t really matter. Just seal the attic hatch with foil to prevent any water from getting through, and that’s fine.
