Check if exposed Styrofoam. would need to be at least covered by metal foil. Maybe more , I don't know fire code

As said it was foil faced. Obviously you would still need a thimble for the exhaust, but so would you for wood. I can't see it being a problem, so long as no exhaust components were close to it. (Radiant heat).

The ad mentions foil faced poly isocyanurate foam which is a bit different animal that styrofoam. Maybe (emphasize _maybe_) fire retardant or fire resistant - check on it. I know solar panel construction calls for that foam because it stands up to the high temperatures in solar panels where the extruded stuff melts.

Use drywall for sound two layers cheap works great. A 2x4 frame wall with 3/4 plywood exterior , 3 1/2 fiberglass batt insulation and two layers of drywall is good for 45 db sound level reduction. I use a sound meter less than 50db at 10 feet from generator

only thing better are cement blocks for sound

for exhaust 15 foot stack up

How about a double stud frame wall, with the inner and outer studs staggered with insulation between all of the studs. Double 5/8" drywall on the inside, the 3/4 ply on the outside. Then the vibration from the inner wall cannot couple to the outer wall.

Those are back flow encloses.

I would be amazed if you could buy one from the manufacture for the $200 price in the ad. Would have to assume someone is selling surplus from a job.

There would likely be no fire retardant material in it. It is designed for water piping inside only.

While 3/4" PT plywood, double stud walls, 3.5" fiberglass insulation, and two layers of sheetrock are great ideas for a 10x10 shed, they are just not doable on a doghouse style generator house. The problem of access to the generator for maintenance makes these construction methods impractical. Well... I guess I could use a front end loader to lift the entire house away from the generator and base, but I don't consider that easy access.

If you could indeed purchase the aluminum enclosure for $200, I would jump on it.

I agree, the aluminum enclosure for $200 is a steal. I would jump on that in a heartbeat and wish I could find something like that in my area at that price.
