ᐅ Mineral wool soaked through during construction phase

Hello dear community,

I visited the construction site today and noticed that the vapor barrier above had slipped into the insulation. Due to the rain, it is now soaking wet. Does it need to be replaced?

I would be very grateful for advice from an expert.

Thank you and best regards

Wherever the glass wool is installed... a bit more information would be helpful. Once the glass wool gets wet, even after drying out, it will never have exactly the same thermal conductivity (lambda value) as it did after manufacturing. Whether this is critical in your case is something you will need to decide.

It’s rock wool installed between the garage ceiling and the house wall, since the garage is not insulated. This was done by the shell builder. The house is not insulated yet.

So it definitely needs to be taken outside for drying anyway. From what I understand, something like this has to be replaced. Don’t you have a construction supervisor?

Yes, he will review and assess it. However, I wanted to ask the experts here in the forum. What is it based on? Current information? Are there any DIN standards or regulations...?

Well, this is a forum, mostly with non-professionals. Not experts. For that, you have your local specialist.
