I am looking at Paroc's publication on wall constructions (http://www.stenull.paroc.se/produktdat/pdf_down/Vaggkonstruktioner.pdf) and wondering about the following text regarding their "Passive house wall":
"Structural stabilization required in the building corners can be placed on the inside of the load-bearing frame."
What could this mean? That the inner non-load-bearing framework for the installation layer should be attached in a specific way to the load-bearing frame in the corners?
Shouldn't the inner framework be attached to the floor and ceiling everywhere?

...) Bracing/stabilization is, as Andersmc says, done with perforated tape on the inside of the outer frame.Hmm, diagonally from one wall to the other (which meets it at a right angle)? Or do you just mean between the inside corner and the first stud?
Should one perhaps have diagonal braces between all the studs in the wall where possible?
...but what do you do if you have, for example, a large sliding door section in the middle, like 5.5 meters long?

You should have a "cross" of two bands, from hammarband to syll. Make it as long as you can, but it does not need to be more than over half the length of the wall, as it still braces the entire structure. However, just having bands between two studs does not brace well.
Hmm, I can't find anything in Träguiden about this.
How does it work in the corner? From the rafter plate of one wall to the sill of the other wall and vice versa? Or is it irrelevant to "connect" the walls with the plates and instead just make crosses on each wall separately?
Paroc's description specifically mentions the corners...

You should have a "cross" of perforated strap on each wall. It does not matter where on the wall they are located: the placement is dictated largely by where your windows are. The straps also do not need to be positioned over each other in exactly a cross. They can be placed separately if that works better.
These straps are normally used solely for diagonal bracing. They do not function to hold the walls to the slab or to connect two perpendicular walls.

Bringing up this thread again as I have a new question.
Would it work well to have a layer of OSB on the inside of the load-bearing stud frame and then continue inward with insulation, vapor barrier, insulation?
Maybe it becomes too tight with OSB so that there's a "double vapor barrier" effect (meaning moisture could "get trapped" between the vapor barrier and OSB)?
The reason I might want to do this is that I want to have wall blocks delivered by a house manufacturer, and I assume they would prefer to place the OSB at the factory to stiffen the blocks for transport.

What I envisioned was from the inside out something like this:
Plasterboard
OSB, Plywood or raw board
Non-load-bearing frame with insulation (70 mm)
Vapor barrier
Insulation (120 mm)
OSB - so this is the layer I'm considering
Load-bearing frame with insulation (195 mm or more)
Insulation in the form of facade boards (45 mm or more)
Wind barrier if the boards don't serve that function
Air gap
Wood facade
I think I thought wrong, it looks like it's outside the frame you want OSB: http://www.firmakubus.pl/se/domy_szkieletowe.htm and http://www.firmakubus.pl/se/images/Haugesund/flashThum/index.html

I'm sitting with the same thought. You want stabilization of the studs on both sides, but how do you solve this in a professional way when you have two independent frame structures as above?
How did you build prosit?
