Hello,
I have a Gullringshus built in 1978. The walls are modules of some kind of 12mm building board, I don't know the width but it doesn't seem to be a standard size. I am now planning to renovate a room and thought of putting drywall on the walls to make it a bit nicer/more stable/less prone to cracking.
However, according to the drawings, there is pastfolie behind the building board. Can I safely screw the drywall directly onto the existing panels, or will I perforate/damage the plastic film?
I don't know where the studs are; it seems like there is a horizontal sparse panel behind the board, 20x95 c 400.
What should I do?
