That's what it looks like to me, too. Here's the largest section pulled out 24 hours ago- the piece from under the wall.
That white insulation stuff is worthless. But, it does seem to be the barrier between the under wrap and the wood floor... the floor looks ok into the dinette/kitchen area, but the while insulation is wet.
Any holes (pretty small) in that black wrap we patched until I can grab some eternabond.
