Very robust air gaps for Swedish conditions, but that's probably not a disadvantage.

No, to keep the insulation in place. I was thinking of something equally good on the inside but cheaper than plywood inside. Right now, the wall plans look like this from the outside in:
Vertical paneling
40mm battens for air circulation
3mm plywood
150mm rockwool insulation
3mm plywood
50mm battens for air circulation
50mm rockwool insulation
12mm construction board similar to OSB
12mm gypsum/wood paneling
3mm plywood, what is that? Are you thinking of masonite?

Then, 40mm battens are not enough, you also need ströläst to have approved ventilation.

there will be no air gaps at all the way he has planned the construction
 
The choice of timber is not so extensive here in North Africa. So I've had to split most of it myself.
So it ended up being 40mm x 40mm for the air gap.
The wall studs are 150mm x 55mm put together with 120mm French galvanized screws.
 
You can have staggered "releases" in the horizontal battens, otherwise there will be no ventilation.

Yes, I know, but they are too few.
The solution you mention is essentially equal to zero ventilation.

There are tons of studies and research on this area; we read a lot about this when I studied.

You must have double to get adequate ventilation, as all tests showed.

Most manufacturers recommend it now.
 
You're probably right, but it also depends on what you are ventilating against. In Sweden today, it's a lot about compensating for the problems with diffusion-tight paints and using wood that is not dry. I imagine that the conditions in Morocco are a bit different. But I do not know that for sure. I think KillerBee should check out their neighbors' building methods.
 
Hehe my "neighbors'" construction style is brick houses with fake planks and have no insulation whatsoever. Either for warmth or the cold days.

What's wrong with my construction method?
Once upon a time, neither air space inside nor outside was used. Now 45mm x 70mm is recommended while many companies in Sweden use 45mm x 35mm.
That's how I was thinking about the paneling. The right image

you get none or minimal ventilation which is the whole point.
especially if you have vertical paneling, you must have both nail and counter battens

I appreciate the answers you give, they are very helpful so don't get me wrong now.
But when I worked in construction in Sweden, ströläkt was never used in walls, only in roofs?
 
No, until the 70s, air gaps were not commonly used in connection with wooden facades at all. It is diffusion-tight paints and the presence of wood that is not carpenter dry that have driven this development. It is always good to ventilate the facade, but if you know which paint to use and that the wood is dry, it is not so important.
 
The rules are first selection Swedish imported timber which, according to samples, has a moisture content of about 10%. And facade color is not determined. I'm considering Lasera it.
 
That sounds good. Just make sure there are no other unpleasant things, such as small rodents, that we don't have in Sweden.
 
The remaining timber for the paneling is well-packaged with the original packaging and weather-protected under an awning on a moisture-insulated elevated platform. These too I have imported from Sweden.

During this time of year, there aren't many insects or rodents, and all open packages are inspected and repositioned.
 
That sounds like an exciting project. What kind of connection do you have to Morocco?
