We used a similar product ("Ensolite", IIRC) 20 years ago on a boat that was unfinished glass throughout the interior. We glued it on with a paste glue, the name of which I don't recall.
Being closed cell, it works very well. We also put some furring strips up to aid in attaching a liner (we stapled that perforated white vinyl, and sewed a section for the forward cabin and glued it up as well)
The vinyl lasted about 8 - 10 years, and the next owner then recovered the insulation with another material of his choice... the insulation itself has stood the test of time.
There's a lot of over-your-head awkward gluing involved, but it certainly stopped the condensation problem that we'd had prior to this upgrade.
Edit: just saw JohnR's post re: flammability - good point, we never had a problem but then we never had a fire.......
