guys, I'm planning on dry-lining my attached garage by building stud walls and using plasterboard to finish it off.
my question is that one of the walls is a single skin wall built with blocks and rendered on the outside.
I know I need to use some sort of membrane, but I am looking for advice with regards what kind to use and where to put it. and do i only need to use it on the one wall that is single skin, the others are a cavity.
i will be filling in the gaps in the stud wall with kingspan insulation.
