What resources to look at for building a quiet generator compartment?

[dtcerrato]

Sheet lead may be found at commercial/industrial drywall suppliers as it is used in high secret priority construction.

Gorilla glue says 200F max once in service. 

I remembered that a guy I know in Kansas City does MRI machines and similar for hospitals.  I recall him saying he recovers lots of lead sheet from projects.  I think he melts it to make bullets for reloading.  It might be worth making the 16 hour round trip if he has some lead sheet.

Being in interior build out in my earlier construction years we dealt a lot with lead sheeting. It was incorporated in between layers of drywall and mazes in the hvac duck work, conduit runs etc. For what was referred to at "super snooper" rooms in high rise penthouse security suites for companies like Northrop Grumman (space shuttle) Raytheon (patriot missile) & the like. It is (was) also used as "curtains" over partitions that went only to drop ceilings. In an earlier time I scrapped the stuff for $$$. Not so much now... We were also in medical modality construction - lots & lots of leads there...

I didn't read thru all of the thread, but Dick Wright at Wrico International has some very thick insulation that is about the best thing you can use for insulation in your generator compartment.  It ain't cheap, but nobody will hear you screaming about the price with that stuff around. 

I used it when I re-did my generator compartment last summer and now I have to look at the monitor panel to see if my generator is running or not.  Well, not quite.

Does anyone have any recommendations on an acoustical engineering firm that would work on a small project like this?  I realize it will probably cost several thousand dollars for their services.

You are willing to spend several thousand dollars?  Just how important is it to have your generator quiet, quiet?  Don't you use your coach as a food vendor out at a desert function?  Is it that necessary to have a quiet, quiet generator? 
After 140 responses, Brian, I'd say go for it yourself with all the suggestions you have been given.  Put that several thousand in some lead, soundproofing, plywood and build a box with some 90* bends to quiet down the fans and go for it.

I use my bus a few times per year to go to various rocketry events including one event in the desert.  One of my friends used to sell food at the desert event, but she hasn't done it for a couple of years.

I bet an acoustical engineer could design something without using lead.  A lot of people are telling me lead isn't really used anymore.  I am having some trouble coming up with a good adhesive that won't fail from the heat soak after turning the generator off.  Contact cement would be easiest, but it only handles 180 degrees.  High temp epoxies seem to require curing at high temperatures.

Dick's panels are also self adhesive. Give Gary benett from B&B Coach a call and he will help you out. 

[belfert]

I'm trying to go with what you guys are telling me, but I run into problems with just about everything.  Several recommendations to use lead.  I can't find any glue that will adhere lead and withstand the heat soak without having to cure the glue at several hundred degrees.  Well, there are small quantity glues that will work, but I don't want to buy dozens of tiny little tubes of glue.

I will probably order the foam panels from Wrico, but the shipping is very expensive.  It sounds like shipping four pieces of the stuff is about $200.

I'm confused.  I thought B&B Coach Works went out of business, or was that a different company in Las Vegas?

Would B&B Coach Works install my generator for me if I was able to get my bus to Las Vegas?  The worst part would be driving to Las Vegas with no power for air conditioning.

Brian I sent you a PM.

Gary Bennett at B&B Coachworks is still in business but working out of his home garage in Vegas.  He can probably do this for you.  Give him a call at 702.592.6746.   I was there yesterday and he was there.

I don't know what he is after, without knowing the pitch and frequency of his generator set it is going to be hit and miss and wasted money ,my 12500 QD Onan is @ 42 dba under a load @ 20 ft and is quite

Belfert don't know why you can't use heavy duty staples or screws with fender washers instead of glue, did you ever look at Acoustiblok he's got some impressive products and a free app/tool for designing a system.
