Exterior cladding - how big air gap against the concrete block wall
Hello! 
How far out from the edge beam/Leca row should one aim to place the panel?
I'm ordering trusses on Monday and would like to hear as many opinions as possible on where I should attach the sill on the Leca.
Some say the panel should rest against the Leca, while others suggest you can build so that the outer gypsum ends up 'edge to edge' with the Leca and gets a 28mm (28x70 nail batten) as an air gap.
As it stands today, the wall will look like this (from the outside):
Mansion panel
Nail batten
Outer gypsum
45x145
Vapor barrier
11mm OSB
13mm GYPSUM

I prefer to only lay the framework with the edge beam, why should gypsum etc. be able to absorb water?

Are you saying that in my case you would have placed the sill flush with the (outer) edge of the leca and let both the outer gypsum and nailing strip 'build out' from the edge?
My spontaneous feeling is that it wouldn't be wrong to have an air gap at the bottom between the panel and the leca, somewhat depending on how far down towards the edge beam you let the panel go?

Correct. Or I could let the plasterboard finish a few centimeters above the lecablock. That is, place a batten or something else as a spacer when putting up the boards. This is if you want the plasterboard inside the edge of the beam/foundation. It depends a bit on the measurements on the drawings if you build that way, if you are building freehand, you do as you please.
