I am getting tired of the styrofoam beads floating around every time I remove my engine hatches. What is everyone using for insulation on their hatch covers?

One Inch High-R with reflective aluminum, works very good.

Same here

Works very well.
The reflective material is just as or more important than the foam ...
Fire resistance?

What about fire resistance or high heat resistance? Is this material able to handle that? Probably better than the foam bead stuff I have now.
yes

Yes, you can find this material with foam that is fire-proof/resistant.

When I replaced the back desk with teak, the hatch had the peanut shell crap on it. I made a new hatch out of 3/4 teak and attach the High-R to it. Very little engin noise and very little heat. The only noise I get now is, some dummy mounted an electric pump to the deck stringer without rubber mounting

. MUST FIX But that is another story.

I have that Cheap a$$ foam stuff too and it's just about gone. I was thinking of using Dynamat, the stuff hot-rodders use, to line the inside of my hatches...

Holy Moley! I just thought that drumming sound in my head when I was running the boat was the "cool" sound of my inboard! Rick, where did you buy the high R foam? I almost bought the "marine" sound insulation, but your idea sounds a lot better.
Thanks

Try SOUNDOWN industries or just google for SOUNDOWN (might be spelled with two "D" s.
When we repowered,we added this to the factory insulation which was a similar aluminum/foam material, however the SOUNDOWN has a layer of what appears to be some sort of flexible LEAD in the middle.
I can tell you this stuff is VERY HEAVY per sq ft!
With this in the floor of the cockpit the 10 Meter is actually QUIETER with the diesels than with the 454's.

Thanks for the tip on Sundown. I'll check it out. I checked out the hot rod stuff, and it sounds sort of simliar - lead interlayer - expensive and heavy though. I'm looking for "cheap but effective", so I'll also check out my local Lowes, HD, etc. We're taking a month long trip on the NYS canal system in late June so I have a real incentive to cut down on the inboard noise from my single V-8 under the center of the cockpit!
