Basement insulation

That is exactly what I wrote. It is the task of the bitumen thick coating, with which the panels were glued, to remain sealed.

Well, you said something would come in anyway - and that’s what I was referring to.

Sorry that someone wanted to help you ;).

Between the plates I meant, not behind the plates. I don't know why there is foam in there.

We also used foam in some places. But really only partially, in certain spots. The expert inspected it and found it to be okay. In that respect, I think it's fine.

What kind of insulation do you have? EPS, XPS?
