Have added to the home about 30 sqm (living room). The roof is finished (flat roof). Have already partly equipped the intermediate rafters with clamping felt. Next I wanted to apply the vapor barrier to the rafters. Now I noticed today that on the wall to the ceiling are water drops. I think this is condensation because the room is still quite damp.
Is it advisable to apply the vapor barrier now or should the moisture be 100 percent out of the false ceiling?
