Starting to wonder how tightly the renovation plasterboard should fit against each other or a trim around the front door that isn't removed. Byggmax says 2-3 mm between edges but that's not something I've heard or seen elsewhere.
The plasterboards taper a couple of cm out to the edges on both long sides and are also beveled. I guess they should be cut so that the thickness of the board is even at wall corners and that they become unbeveled.
