Hello, I need your assessment. I have extended my house by about 30 sqm (living room). The roof is finished (flat roof). I have partially already installed the insulation between the rafters. Next, I wanted to apply the vapor barrier on the rafters. Today I noticed that there are water droplets on the wall near the ceiling. I think this is condensate because the room is still quite humid. Is it advisable to apply the vapor barrier now, or should the moisture be 100 percent out of the cavity first? Thanks in advance. Lg

Why is the room so damp? I assume because it is not heated yet? Or because the screed is still drying?

Personally, I wouldn’t seal it up if it is still that wet. Additionally, one should be very, very sure that the moisture is really condensation and not coming from outside.

Hello, the masonry is still partially damp, hence the moisture in the room. I already have dehumidifiers running. I will also wait until it is completely dry and then close it. Thank you.
