We are building a house, a prefabricated house that was assembled a little over a week ago. On the long sides, there is still some facade missing that is supposed to connect two prefabricated wall elements. Now it has started to rain quite heavily, and in the places where the facade is missing, the underlying wind barrier has become wet, and it looks like it is soaked through to the insulation directly behind it.
What should one think about this? Inside the house, it is dry, but as mentioned, it seems like the insulation has become wet or at least damp from the outside. Will it dry out spontaneously if the weather stays nice for a while, or will it need to be replaced? I assume the plan is to put up the remaining facade next week, as soon as they're done with the roof tiles.

The question is whether only the fabric is wet, because if the insulation is wet as well, it's not good - it should then be given the opportunity to dry properly or be replaced. Why hasn't the unfinished wall been covered with tarps?
We asked ourselves the same question. Our carpenter said that there's not a significant amount of moisture reaching the insulation and that it will dry up without issues. Apparently, many constructions stand like this for a long time without problems. As we understand it, the insulation doesn't actively absorb any moisture, so it shouldn't be a concern. In any case, they've put up tarpaulin now, so no more rain should get in.
More concerns.... we believe and hope that everything had time to dry out because the weather was fine for quite a while before they put up the facade. The house was assembled, but the wind barrier was stapled and not taped together at the seams between the blocks. How does it actually work with the insulation, I've understood that it's a dead material that nothing grows in, but it still seems very important that it doesn't get wet... can someone explain how/why? IF a bit of water did get into a seam so that the insulation became damp, will that automatically give us moisture issues in the future since the wind barrier is tight and doesn't let it out? Is it really completely waterproof, it didn't feel like it?!
The question came up again now that it rained heavily over the weekend, and we have a facade below two window doors on the upper floor that is not protected at the bottom by a strip. This means that rainwater comes in (runs down along the door) into the air gap behind the panel and has made the back of the wood wet, as well as the wind barrier. The strips have not been installed yet because the balcony needs to go up first. We've tried to cover the gaps with plastic, but it was gone now.
What should we do? Breaking up the facade doesn't feel right! Our hope is that we can rely on the airflow in the air gap to dry it out over time.

Regarding whether the wind membrane is waterproof or not, I don't know, but I spontaneously think that it should not be diffusion-tight at least, which means that moisture can migrate out through the membrane.
