Mass Loaded Vinyl vs. Foam for sound deadening
I was talking with a friend of mine today who has had a number of conversion vans in the past, and he swears by MLV (mass loaded vinyl) for its sound deadening properties. He recommends it on all walls, ceiling, and floors. I priced it out, and it's VERY expensive, and I don't see it as that much value (not to mention I don't want the bus to weigh more than it needs to). Given I plan to put 1" foam board below the plywood subfloor, as well as closed-cell spray (and maybe some foam board) in the walls and ceiling, is there any benefit to MLV? Has anyone worked with it on more than just the engine compartment?
