[C320-list] Diesel sound proofing

[kskis at aol.com]

I've heard soundproofing will reduce the amount of air circulation.  Particularly with the limited space in the 320 engine area, this could in-turn will encourage overheating and underperformance of the alternator.  Anyone with experience one way or the other?  Neil Kornblatt Harmony #963

I’ve used Dynamat in my RV to reduce engine noise and wind noise and it works really well.  It’s also very thin unlike the old marine style insulation.  No reason it wouldn’t be at least as good as the marine stuff.  It’s expensive, but I think it’s as good as anything out there.
