Does Isover's spacer sleeve provide an air gap (facade board)?
Here are no crossed battens.Nyfniken said:

you also set the battens so that the insulation is held in place.No, but isn't the distance some inch longer than the insulation is thick?
It gives the same effect.
you use the spacer sleeve so that the insulation isn't compressed, and it prevents air in the insulation.
Interesting discussion!
Gives a face to the saying painting oneself into a corner
I have previously explained my view and the advantages of horizontal paneling.
But now I've started to wonder.
Since I have an unventilated so-called climate attic, there is no air gap up under the roof deck. And, of course, the meticulous carpenters have built the walls super tight at the connection between the outer wall's Z-panel and the roof deck and the outdoor drywall, which serves as a wind barrier in the walls and the roof deck.
Hmmm, maybe I should go up with the hole saw and make some ventilation holes in the outer panel just under the roof, so all the moist air can escape.
But you can see from below how the joints in the Z-panel are not airtight. Maybe that's enough?

you probably know where I stand on the issue if you've been following the thread.KnockOnWood said:

Since I have an unventilated so-called climate attic, there is no air gap up under the tongue and groove roof. And of course, the meticulous carpenters have built the walls super tightly at the connection between the outer wall's Z-panel and the tongue and groove in the roof and the exterior gypsum, which acts as a wind barrier in the walls and tongue and groove.
Hmmm, maybe I should get up there with the hole saw and make some ventilation holes in the outer paneling just below the roof, so all the moist air can escape.
But when looking from below, you can see how untight the joints in the Z-panel are. Maybe that's enough?
I would have somehow ventilated at the top if I were you; it's such an easy solution.
Don't forget the insect net.
I wouldn't be super surprised if the vertical spikläkten is lost in translation between the designer and the technical documenter who wrote the assembly instructions.
They have hardly written the section about needing vertical läkt by mistake.

what does isover's documentation have to do with new construction or renovation of a house?
That's right, thanks!
Just drilling a bunch of Ø30 mm holes would be like giving free housing to thousands of wasps.
Just move in, you know
Maybe I'll have to make a small test hole and stick in the moisture meter to see how things are in there in the dark.
Presumably a lot when choosing to use one of their systems, which is what this thread largely discusses, hence the title "Does Isover’s distance sleeve provide an air gap (facade board)?"SBH said:
It's even you who has referred to their installation documentation and advocated that the supplier of their system knows best.
So. Now I have emailed their support.Who will take on the task of calling Isover?
By the way, I noticed that they have somewhat disclaimed responsibility: "There is also standing panel with cover boards where the base board is at least 19 x 150 mm and the cover board 22 x 150 mm. Here the batten board is quite wide, which forms ventilation channels behind the cover board, see image below."
(Why on earth would anyone buy panel where there is a 3 mm difference in thickness?)

Yes, clearly some air will pass behind the cover board.
But studies have shown that this is not sufficient and a free air gap of about 20mm is optimal.
There is quite a lot of water that needs to be ventilated away so it doesn't push into the facade.
Then something can happen like a gutter becomes overfull, a storm, a seal becomes old, a fastening is removed and forgotten to be put back, etc., etc.
The stresses on the air gap can then be very large, and the turnover with dry air that can ventilate away moisture needs to be substantial.
It's written with a bit of humor, I think
"Horizontal paneling consists of panels that are at least 22 x 175 mm," they write.
So my 22 x 120 mm Z-panel is not good enough then?
So it's starting to come together a bit now after this enormous number of posts, i.e., #267, 268, that what is almost self-evident for a person like, for example, SBH should be so difficult for some to accept is strange. That is, with the best understanding under the right conditions, one can build with these boards and spacers without any extra vertical ribs if they are not needed for other reasons. And completely without problems or increased risks.
