Hi
I need some advice regarding the construction of a wall. Starting from the outside going inwards.
Wooden facade
Air gap
Asphalt board
Insulation, isover
Wind barrier
OSB board
Gypsum board
Wallpaper
The wall is framed with 12 cm studs.
Is an additional moisture barrier needed? What do you think about the construction, can it be done this way?

Do it like this from the outside
Wooden facade
Air gap 28*70 preferably beveled
Wind barrier instead of fiberboard, goes faster
Insulation
No wind barrier on the warm side, there should be plastic to make it airtight,
otherwise, warm indoor air can condense in the wall leading to mold.
OSB board, tongue and groove board or similar.
Gypsum board

and I would gladly see a switch from the windbreaker to a modern wind barrier instead. Breathes in one direction and is tight in the other.
Asfan has the advantage of stabilizing the construction before the inner gypsum is installed.

mats_o solutions aren't wrong either, mine were just suggestions and asfan isn't difficult to work with. mats_o, when you say modern wind protection, are you thinking of something like Isover Vario Duplex? Have you used it and does it work well? I guess it could be just as good a solution in old houses where it can be difficult to get it 100% airtight.
I think so 
I've only tried Paroc's version when I built my insulated storage shed after tips from an acquaintance who is a former carpenter. (he also got me a nice price)
The big advantage I see is partly the weight; a 25X2.70 roll doesn't weigh much more than a single asfa board.
Partly the speed with which you can put it up. You either attach it with roofing nails (that's what I did) or with a heavy-duty stapler.
Just attach it at the top of the frame and then you go and unroll the wall. I chose to go at the same height as the top plate so I could roll the build around that way.
Suddenly the walls were weatherproof.
The downside is if you're building something that you won't be putting panels on the inside on. For example, a cold storage. The fabric doesn't stabilize at all in the same way as, say, asfa, so if you're not putting panels on the inside, I would go with asfa, but otherwise, I think the fabrics are worth considering.

I put windbreak fabric on the garage last year, it's very easy if you are two people - one unrolls the fabric and the other attaches it. I used an electric staple gun and will never use felt, asfaboard, etc. after trying the fabric. I don't remember the brand, but it was green/white and kept the insulation dry during an unexpected rain shower as well.
