ᐅ Insulation for sloped ceilings, moisture in the attic, drywall panels

Hello, my construction company Deura installed the wrong insulation on the upper floor, which is causing moisture problems in the bathroom and attic.
They installed more or less insulation between the rafters, then a vapor barrier foil, followed by an additional crosswise insulation layer, and finally the drywall. This can’t be correct, can it?
Because of this, moisture is now coming through the drywall into the first layer of insulation, which has become damp.

What can be done about this now?

Hello Thomas,

They more or less installed insulation between the joists, then a vapor barrier foil, followed by insulation across the joists, and finally the drywall. This can't be correct, can it? As a result, moisture is now passing through the drywall into the first layer of insulation, which has become damp.
