Hello
I need help with connecting the vapor barrier.
I have already renovated the side rooms in my old Appenzeller wooden house. Now the attic is next. I have sketched this on the two attached drawings (a cross-section through the rafters and a cross-section through the main beam).
However, I am not sure where to connect the vapor barrier. The main beam is covered by about 30mm (1 inch) thick rough-sawn boards, and I would prefer not to remove them because they are in good condition, sit neatly, and also form the ceiling of the rooms below (bathroom and bedroom). Can I attach the vapor barrier airtight to the rough-sawn boards, or will this cause moisture problems?
At the gable walls, I have the same issue at the bottom. Here, I cannot remove the rough-sawn boards because the beginning and end of the boards rest on the gable plates. However, I think the best solution is to attach the vapor barrier airtight just above the rough-sawn boards before installing the insulation, and then extend it upward after insulating.
I would appreciate any advice!
Regards, Nick
