Talk to an engine builder who has a dyno room. My buddies shop has the foam "bumpy" panels insulating his dyno room and it works great. If nobody comes up with a source for you, Ill give him a call.

I have found that sometimes it is better to go to the source that works in acoustical barriers (or whatever I need) than to rely on what a boat maker found and is using. Other times it seems that boaters did a lot of trial and error to come up with what works. In seats for example it blows me away that people are not using space age foam in their seats. Car racers are and they don't take any pounding compared to Offshore. I think sound isolation is the same. These guys know all about sound isolation. Try the link below.

Default Sound Insulation for Boats

Timucin,
If you are looking for a real good sound insulation barrier, there is a place in Marblehead Ma. called Sounddown. Their Phone number is 781-598-4248 They make large boat mufflers and special insulation for boats.

The boat insulation has fiberglass on one surface with a thin layer of Lead in the Middle with another Layer of fiberglass on the outside with an aluminum face that has small fibers running through is as support.

You can cut the stuff with a sharp razor knife and pair of heavy duty shears.

Good luck with your project.
Brian
