For a new headliner I found if you took some of that tight foam mat that people use for camping, you know that 3/4 inch stuff, you could glue it in place on the roof with contact cement. Then apply some fabric, usually a couple of choices from JoAnns fabric or any place like that. It comes with a slight foam backing in rolls that are 6 foot wide or so. You just buy a section that will give you coverage from front to back. Maybe 15 feet of it. Then use spray on contact cement on the foam and the pad. Let it sit till slightly dry and tacky. Start from the middle and work to the edges. Tuck it under the rubber or fold and glue if need be. I did it years ago and just this spring had to shoot a bit more glue to the roof and sleeping pad section in the very back.Try it
I would insulate the ceiling with the "Homedepot" dynamat ...
