My house is located in the southeastern part of Sweden and was built in 1840. It is 1.5 stories. I am renovating our bedroom because it was too small with low head height.
The last time it was renovated was in the 1950s. Please look at the pictures. My question is about the roof. When I opened it completely from the inside, I had 20 cm thick beams in the slope. I first put the oil panel on the entire roof for air circulation. I now have about 17 cm thickness left for insulation. How tightly should I place them?
After insulation, I will place the blue plastic in the picture to protect the room from moisture.
I want to cover everything with the white ceiling board in the picture. Should I place battens and screw the white ceiling into that? Or can I screw the white board directly into the blue plastic and the beams? The challenge is the head height.
