I'd like to insulate the ceiling of my boat's cabin & cover it with sheeting of some sort. Having seen a number of boats with saggy, carpet-covered plywood ceilings, I'm not too fond of that option. My Hewescrafts have had vinyl-covered aluminum, and I thought they held up pretty well.
I have priced out 1/16" aluminum sheets, but before I pull the trigger on materials, I'm looking to see what other options are available. Thoughts?
