Yes, I covered the entire van interior walls with Noico and used thinsulate with the black scrim backing for insulation. Expensive, but probably the one if the best products out there for our applications-doesn’t hold moisture, isn’t toxic, won’t break down or get compacted and won’t warp the wall skin like spray in foam.

Super nice to work with, easy to cut and install with a little spray adhesive. I will point out, Thinsulate does provide a fair bit of acoustic insulation as well as thermal. It will not address any sheet metal resonance or the hollow door sounds though, that’s what the Noico (or dynamat) is for, but it does provide a “blanketing” effect.
