Those of you who have built wooden houses and used asfaboard as a "windboard," have you sealed the joints that occur between the boards in any way?
I mean the joints you get when building upwards with asfaboard, laterally they're nailed (screwed?) into the studs.
What I'm wondering is if it's a mistake not to seal the joints in the asfaboard or if it's not needed at all (insulation-wise).

I have spent the day calling various construction companies and even manufacturers of asfaboard. No one had even considered the idea of sealing the joints. Possibly, if there were a joint that was very unsealed, a gap of one or a couple of centimeters, you could seal it with a strip of tape.
So I can be at ease then.
The builders have already managed to cover the wall externally with paneling and internally with insulation.
It would be a bit troublesome to have to tear down a lot.
Thanks for the quick response.

Used a system from Gullfiber, where there were joints of plastic.

Don't know if it's possible to get these joints separately.
Or how meticulous one should be.
Masonite can be cut to size without needing to be joined.
With a stapler with high pressure, it can be secured without the hassle of nailing.
The main thing is that cold air doesn't blow into the insulation.

You can treat yourself with the expensive PE-folietejpen,
Hello! I thought the asfaboard was out, who uses this? No builders that I know of. UTV gypsum with plastic strips. How long does tape last?
Yes, isn't it so? Does anyone know why? Is gypsum much better? Probably when it comes to density, too dense?
Asfaboard or gypsum?

The Asfabord may have been in at the time the thread was written?
asfa or gypsum, time will tell.
but.
I chose asfa because the boards are very light and therefore easier to put up (especially if you're building taller houses)
asfa is said to insulate somewhat.
asfa breathes better than gypsum.
I once worked on a construction site cutting out for windows where gypsum was used. oh, how it smoked, got this dust in my eyes and hair.
the downside with asfa is when it rains, some dark color runs off and stains the base coat, plus it bends a bit if you haven't nailed it enough.
does anyone have statistics on how common mold is on asfa in walls?

Agree with the Asfa advocates. Easy-to-work-with material, especially at heights. However, one problem is if it remains in place for too long before, for example, the cladding. It can stain windows, etc.
A gypsum board on the outside stabilizes the house well before the interior boards are installed, so the frame doesn't move much when working on laying raw boards on the roof. How is it with asfabord, does it also stabilize the frame? or? or is there a risk that the boards will crack if the walls are not diagonally stabilized with temporary boards?
