Azdel
Azdel is not a miracle product, it's more marketing than anything. Don't believe all the BS on RV brochures.
The Azdel will not come apart itself like luan plywood may if wet, but the filon skin can still delaminate from the Azdel, or the Azdel from the foam/structure. What about the inner layer that the wall covering is applied to? That's typically still luan. It's delamination when any of that happens. Azdel better.......absolutely, Guaranteed to prevent delamination......not so much.
The whole mess is glued together with water based low VOC adhesive.
