Hello
We are considering building a house with Myresjöhus and are wondering about their wall construction. An overview of how it looks can be found here:
https://issuu.com/myresjohus/docs/dinavalmojligheter_2021-04_webb/10
Since Myresjöhus is a very large company, I assume the wall is quite and it has a U-value of 0.164 according to an energy declaration I found, so the insulation capability is essentially similar to many other walls (see below). But how "dangerous" is it to have the vapor barrier right behind the drywall on the inside? Every thing you put up will make a hole in the vapor barrier. Additionally, there is no wood fiberboard behind the drywall, which many other walls have, making it more complicated to put things up.
Compare, for example, with Trivselhus

or A-Hus walls
https://www.a-hus.se/att-bygga-hus/om-vara-hus/vaggkonstruktion
both of which have installation zones and more layers of insulation. What are your opinions? Is the Myresjöhus wall something to "worry" about?
Best regards
Anders

I think it sounds very budget, I thought no one builds like that anymore.
Compare the total insulation thickness in the walls, if it is the same, the multilayer walls will be better.
Both thanks to fewer thermal bridges and the effect of construction errors becoming smaller. (exists in all houses).
The difference can also be that some calculation programs do not take into account the difference that occurs with multiple layers (in normal manual calculations you usually don't).
