Hello
I have received a quote from a company that builds prefabricated houses. I would need help to see if the specification for the exterior walls looks okay:
From outside to inside:
Batton ventilation 28x70 mm c/c 600mm
Wind barrier GU 9 mm
Frame Stud 45x195 mm
Insulation 195 mm
Vapor barrier Age-resistant plastic foil 0.20 mm
Horizontal stud 45x45 mm c/c 600 mm
Insulation 45 mm
Plywood 12 mm
Drywall 13 mm
Top plate Kerto beam 63x300mm
Double Kerto beams over Living Room 2x45x300 mm
Posts l-wood in corners 200x200 mm
Is anything missing? Is the insulation sufficient (for Stockholm)? Any questions we should consider asking? Panel not included.
Thanks in advance!

Windy? Asfaboard?
Traditionally, wind barrier paper has been used, many think it is too low-tech today, while others think it is perfect, especially for the price.
I think you'll get quite varied answers on this...
Personally, I would not hesitate to use wind barrier paper for simpler buildings, garages, sheds. Windy and exterior gypsum board have the advantage that the cladding doesn’t have to go on immediately, as I understand it, or maybe I've misunderstood. I didn't know that exterior gypsum board would have any moisture issues, isn't it treated with some kind of wax or something?
Anyway, you got some tips on a few alternatives...
Otherwise, I think the specs sound perfectly OK.

I recommend some type of wind barrier (not paper) precisely because it is easy to work with and it serves as weather protection during the construction. It's great to have wind and waterproof walls early on so that the future house can be used as storage for materials in the meantime.
Insulation 195 mm
Vapor barrier Age-resistant plastic film 0.20 mm
Horizontal stud inside 45x45 mm c/c 600 mm
Insulation 45 mm
The vapor barrier should still be on the inside of the last insulation. Otherwise, you would have a vapor barrier between two insulations.

It is common to place the diffusion barrier between the insulations. In the 45-millimeter space, there is room to run the electricity and water without risking puncturing the diffusion barrier.
