Great info, thanks for posting!

There's insulation for heat and insulation for noise.
To mitigate noise, you need to attack several issues, vibration as well as noise through the air. That noise is dampened by foam AND mass, a sandwich of foam and lead.
I put some in a boat engine room and it made a big difference. The cost was eye opening, but for a small space it's worth it. I'd do the same if I built a generator box.

My search of van build sites led me to use Thinsulate. It has an R rating that was about 2 higher than I could get with fiberglass, it is mildew and fire resistant, cuts easily, holds in place well and doesn't itch. It wasn't real cheap, but not prohibitive. I think the roll was 5' wide, and one roll will do my 17' Caravel less the forward and back endcaps. Jerry

The tape on ribs sure does help. Recently installed some 1/8” foam tape on ribs and while sitting in the sun for 30 minutes I couldn’t dare touch the outer skins... but the ribs were very easy to touch. Showed me all I needed to know!
