Hello
I am going to build an Attefall house and through Blocket I managed to get ready-made wall elements for free. Sheet metal-insulation-sheet metal. Since the guy wasn't going to use the materials that were left, he left them outside in the rain and bad weather. I haven't picked up the materials yet (it's over 100 km to drive). The person I got them from says that these are wall blocks usually used for building warehouses, etc. I would imagine they are Paroc wall blocks or something similar. I had planned to frame with wood and place these in between.
So the question is whether the wall blocks can withstand being left outside and getting wet? I understand that I can't put up the wall without letting the wall blocks dry first (I don't know how damp they are).
Thanks in advance!

It sounds a bit risky.
Water gets in everywhere if it's not hermetically sealed, and that's hardly the case here.
But the water doesn't escape, it remains trapped by the insulation.
So with a little solar heat, maybe it becomes a veritable fermentation factory inside the wall blocks.
Note, the above are my pessimistic guesses.

Not sure really. But it should probably be something quite stable, that maintains the stability in the blocks. They were almost 100 sqm wall blocks. In the size of 1.2 x 7 m. But I think many blocks were cut, hopefully that doesn't mean water has gotten in.

If they are sandwich panels, there should be no danger.

If they are sandwich panels, they should be placed on the outside of the studs and not in between.

I picked up a load now, but I need to try to get hold of a larger open trailer. I only brought 20 sqm and it's nearly 100 sqm.
The blocks must be of a different type, I think they are some kind of harder gullfiber between the sheets. I don't think the moisture is a problem anyway, because it seems like he had kept them well-covered, as they felt dry.
A huge mountain of insulation they become when they're not compressed like regular insulation during transport. I will need about 50 sqm in the walls, a thought I have is that surely I should be able to use these blocks in the walls and ceiling too? Because of the sheets, maybe I don't even need a blindboten in the joists?

They are probably sandwich panels with stone wool because they look like the ones in the link you sent.
Even if they are supposed to be mounted on the outside of the studs, they should be possible to mount between them, right? Otherwise, the wall will be so thick, and I want to save space. I might have to put an insulation strip on the edges just because the metal sheet sticks out a little from the insulation...
