So, there you go. Adhesives are less of an issue if whatever is supported from the bottom. A layer of the poor man's Dynamat against the metal roof, plus whatever thickness of high density foam to make up the 1" (or foil-backed styro like you suggested), supported by a skin of the melamine-faced masonite tech-screwed into the supporting ribs.

Not only is it deadened and insulated, it's a nicely finished ceiling. Plus, using three different densities of material will give you exponentially greater sound deadening properties.

yup a layer of rubber, and I picked up the higher R (6.5 I think) foil faced sheathing. I may also slide it down the walls, (I have the top plywood off for wiring) but at $13 a sheet for even Foamular, its gettin kind of spendy. might as well do it i spose

fwiw, I found a similar rubber product at Menards. Protectowrap. In addition to a kickass name, it is 10" wide vs 6" and also is a 25' roll for $15.
after doing a few panels I am impressed!
