We have built a new house with Myresjöhus. So have two of our new neighbors. One neighbor built their house a few years ago before Myresjöhus launched the "effect wall," and their wall is about 33cm thick if measured at the entrance door, including the casing. If we measure the same on our house, we also get about 33cm even though we should have the newer effect wall. The other neighbor, who is a few months behind us in the construction phase, has a 36cm thick wall, and it also states that they should have the effect wall.
I find it hard to believe that two walls differing by 3cm in thickness can have the same performance. I have tried to get answers from a technical manager but am getting somewhat unclear responses.
What do you think, did we get the old wall? If so, it would be the biggest scam ever...

It may be that the structure of your wall is different without necessarily being thicker, for example, it could be lättreglar instead of solid studs=decreased thermal bridge, there could be a so-called fasadskiva on the outside=better energy value and various other configurations.
What I have found so far is that the old wall had 240mm insulation + 6mm outer gypsum in addition to nail studs, panel, and hard gypsum on the inside. I haven't found anything about the studs.
Our wall is said to have 220mm studs with insulation and 30mm climate board on the outside.
In response to why the newer neighbor's house had thicker walls, I got:
"They should not be thicker. We have changed the effect wall so that it's 220 mm studs with 30 mm climate board on the outside, and then we insulate with 250 mm insulation between the studs. We are in a transition between these walls but they have the same performance."
That's where it stands now, I haven't gotten a response on what they mean by 250mm insulation between the studs which are only 220mm. I don't understand the answer, but maybe someone here does?

Klimatskiva is a good product from many perspectives, one is that you get better insulation with the same thickness as a framework with intermediate insulation. Another is that the insulation value is usually better than "regular" wool insulation (at the same thickness) 220mm studs & insulation + 30mm Klimatskiva = 250mm... could that be what he means?
I have now received some more info, apparently it looks like this:
Older wall: interior gypsum, 240mm studs/insulation, 6mm exterior gypsum, nail batten, panel
Our wall: interior gypsum, 220mm studs/insulation, 30mm climate board, weather protection, nail batten, panel
Newest wall: 220mm studs with 30mm climate board strips and 250mm insulation in between, weather protection, double nail batten, panel
They first said there wouldn't be a difference, and now they're saying that it's a standing nail batten that makes the neighbor's wall thicker, so I'm going to the neighbor's tonight to stick my fingers under the panel and check.
