How wet is core insulation allowed to be? (during installation)

Since it is currently raining a bit, I would be interested to know how wet cavity insulation is allowed to get. In many places (especially from the manufacturers - but also elsewhere) one reads that cavity insulation does not collapse or lose its insulating properties but that the whole thing is water-repellent and dries out again. Is that really the case? Our insulation is well sealed and was only slightly wet at the edges - but then dried relatively quickly again. Today water dripped between the window insulation (PU, purple) and the stone (even though the PU was covered on top with a foil) - this time unfortunately from above onto the insulation. I felt it and think that the insulation got about 2 cm "wet" (of course, I then put another foil over it so that no more water drips in). At many other construction sites I have observed, the insulation is covered but never 100% - more like 98% - I often still find yellow. Does anyone have any knowledge on this? I have the feeling that either people say "doesn't matter" or "everything has to be replaced." Thanks and best regards

Hello,

At many other construction sites I've observed, the insulation is covered, but never 100% – more like 98% – I often still find yellow stuff.
Does anyone have any idea? I have the feeling that either people say "doesn't matter", or "everything must be replaced".

You won't find 100% at any construction site; not even where a tent has been set up.

Basically, insulation should not get wet; the last 2-3% don't matter.

Rhine regards

As the construction expert has already written... It should not get wet but being 100% dry is also not possible...

So if it gets wet, hope that the hydrophobic coating was strong enough and the edges dry again?

Easier said than done... maybe with more routine and cheaper houses
