Does Isover's spacer sleeve provide an air gap (facade board)?

Don't pretend, hopefully nothing is unclear in that post for someone with your capacities. That you're doing some sort of ring dance with SBH is one thing, but as I see it, it looks extremely boring, not to say silly. I wrote earlier and now just to give a signal that what you are doing does not lead anywhere.

It doesn't interest me enough and doesn't add any value to the thread for me to get involved in this chatter. The only difference would be that it would soon crystallize into a much more fact-based direction where each party would have to show through their own responses and rough calculations what they are referring to. And then no laboratory conditions help, when it's easy to question if they're relevant in reality.

Perhaps you could send PMs to each other instead of all these short posts without much value, at least for me as a reader. Yes, continue if you want, nothing forces me to read them, but still.

SHB and I will take our discussion over PM.

Come up with some fact-based theories or calculations if you wish, showing that horizontal battens alone provide an adequate air gap.
That is what I have been asking for all along but no one has managed to present anything, whereas I have presented several different ones.

Don't pretend to be dense, hopefully nothing is unclear in that post for someone with your capabilities. That you play SBH in some sort of ring game may be true, but as I see it, it looks incredibly dull, not to say silly. I wrote earlier and now just to give a little signal that it doesn't move forward the way you're going.

It doesn't interest me enough, and it also doesn't add any value to the thread for me to join this chatter. The only difference would be that quite soon it would crystallize into a much more fact-based direction where each party would immediately have to show through their own responses and rough calculations what they mean. And there, no lab walls would help under conditions where it's quite easy to question if they're relevant in real-world walls.

Perhaps you could send PMs to each other instead of all these short posts with little value at least for me as a reader. Yes, continue if you want; nothing forces me to read, but still.

By the way, why do you say that I play with SHB?
he is a trained civilian with more years than me in the industry so he should know his stuff, right?

If I go to Isovers website and click on Fasadskiva, it says under the heading "Air gap behind wood paneling" the following:
"Ventilation behind wood paneling is as important as behind other facade materials ... With vertical paneling ... Here the nailing rule is set horizontally, which means that no air gap is formed. By placing a batten vertically before the horizontal nailing rule is set, an air gap is created."

Have you really read the installation instructions when you built all those houses?

If I go to Isover's website and click on Fasadskiva, under the heading "Air gap behind wood panel" it states the following:
"Ventilation behind wood paneling is just as important as behind other facade materials... For vertical paneling... Here, the nail batten is placed horizontally, which means no air gap is formed. By placing a batten vertically before setting the horizontal nail batten, an air gap is created."

Have you really read the installation instructions when you built all those houses?

They quite clearly support my claims, I think.
and show that the installations some have made in the thread are completely incorrect.

If I go to Isover's website and click on Facade board, it says under the heading "Air gap behind wood panel" the following:
"Ventilation behind wood panel is as important as behind other facade materials ... With vertical panel ... Here the nail batten is placed horizontally which means no air gap is created. By placing battens vertically before the horizontal nail batten is set, an air gap is created."

Have you really read the installation instructions when you've built all those houses?

But this is common knowledge and yet I have built quite a few properties and never experienced skipping the air gap, except when building single-step sealed facades a number of years ago.

The people in the thread who build in this way with only a horizontal batten are basically constructing a single-step sealed facade. We all know about the problems that can arise.

Do you mean K-ritnigar?

 

[Nyfniken]

You mean K-ritnigar?

You can call it whatever you want. Every serious builder who receives documents with obvious or suspected deficiencies naturally points this out back up the chain to confirm that the documents are correct.

Both you and hul have somehow gravely failed in several essential steps in your constructions if what has become the thread's absurd writing circus, i.e., if vertical battens are so important/necessary, turns out to be crucial. Several of the questions that some have introduced, such as what do the numbers from the studies mean and at what levels should we view it as problematic? What percentage of covering surface needs to be freed by slots due to bottom/cap boards for vertical ventilation to be sufficient? Why is the vertical component seen as so important; don't different water transports apart from free occur equally in all directions?

I haven't built a thing. But I find the subject interesting.

"Why is the vertical component seen as so important; don't different water transports apart from free occur equally in all directions?" - I don't know if that was a question directed at me, but at the end of these horizontal compartments sit the corner boards/equivalent. That air is trapped and doesn't go anywhere.

"Why is the vertical component considered so important, doesn't the transport of water occur freely in all directions?" - I don't know if that was a question directed at me, but at the end of these horizontal sections sit the knot boards/equivalent. That air is trapped and doesn't go anywhere.

That's exactly what I'm trying to say, that the air gets trapped, creating no free air flow.
To ventilate out humid air, new dry air is needed. Without a high air turnover, it's impossible.

I understand it is drawn incorrectly on purpose you mean?

No, if it's drawn on purpose then it's not drawn incorrectly. But everyone makes mistakes, even those behind desks.

Stranger things have happened than a designer forgetting to include some battens in a drawing. If you then get a drawing in your hand where such is missing where you think it should be included, it would be wise to check with the person who made the drawing if it really should be that way.

Or you pretend it's raining and build exactly according to the drawing and blame someone else when it turns out that it's wrong (but as it was drawn).

No, if it is drawn intentionally then it's not drawn incorrectly. But everyone makes mistakes, even those behind desks.

Or you can act like it's raining and build exactly according to the drawing and blame someone else when it turns out to be incorrect (but as it was drawn).

If we had built blindly according to the drawings, there would have been quite a lot wrong; designers are human too, mistakes are made all the time.

Then you should know that those who draw structural drawings are often newly graduated designers, and they start by just drawing CAD. It's easy then to miss something or not notice a mistake if it's made. If they mention it in their description, then it should of course be there.

Moreover, it's quite logical that a ventilation gap is needed.

The ones I know are absolutely no doves when it comes to construction drawings.

But now Isover says that slope with horizontal and vertical battens is required for wood paneling to create an air gap.

You said earlier that you followed Isover because they are the supplier and should know.
Doesn't that still apply?

 

[hul]

all producers change as needed.

what is the slope you need?

Ventilation that I think everyone understood except you.

 

[hul]

Haven't complained about your spelling.

Can you answer how you feel about Isover now also advocating for cross-battening?

 

[hul]

see previous post

Can you respond to how you feel about Isover (supplier) now recommending cross battens to create a proper air gap?
