Mex, do you get cool nights? Do you have any trouble with condensation between the outer shell and the space blanket? Have you looked in there?
My background is in S&B construction, so my thinking may be a bit off, but I am leery of impermeable layers. I am used to thinking that vapor has to be able to travel through the layers.
That said, I have seen no problems in my old van, which has stock assembly of closed cell foam (loosely stuck onto metal roof), air gap, then fiber headliner with sprayed on thin foam and thin fabric. There could be mold in there I don't know about, though
