I have completed the ground floor of the house and will start on the upper floor soon. I have insulated the exterior walls with 195 but have not yet added plastic or installed 45 insulation. I also haven't put plastic on the ceiling, so there is still the external temperature there. Now there has been a lot of condensation on the wind fabrics and the outer side of the insulation. Why? Same temperature outside as inside and no condensation from below since I have plasticized the ceiling from underneath. Does anyone have any idea why and what I can do about it? Sorry if it's hard to read, I will edit when I get home/sebbe
