Insulation?

A sort-of self-built SMB in the works?

Things that I would look at:
R Value
Combustion Products (probable inhalation poisoning in the event of a fire)
Thickness
Ease of install (encapsulation required?, etc.)
Special adhesives required?

FWIW in researching a totally unrelated project I had cause to examine the urethane foam 4' x 8' panels at the local home store. It was a minor epiphany to notice just how quiet that isle was. They're rigid panels though, would require cutting and splicing to make them conform to even simple bends.

I glued some of the Reflectix mylar foil covered bubble wrap stuff to the underside of the Suburban's roof before reinstalling it's headliner. That made a large difference in interior temps. During the install the bottom of the roof metal was easily 20* hotter than the bottom of the Reflectix.

Looks like their System 15 kit (15 cubic feet of foam) is 39 lbs and their System 50 (50 cubic feet) kit is 60 lbs. I guess that is the total kit weight and not the actual foam weight.

I think that I'd go with the Flame Retardant version (http://www.rhhfoamsystems.com/systemflame.php) of the foam even though it takes a 1.7 hit on R value over the non flame retardant foam.

I think it is going to a good all arounder...camping (slash) hauling the Hoons on dirt bike trips, selling ice cream to the kiddies on weekends...and delivering flowers during the week...(well those last two are a bit made up:p)

The aluminum bubble wrap stuff works well, I put some on the inside of a truck before. I put 1" foam stuff in an aluminum cap and it did make it quieter but didn't make a bit of difference in temperature, the r value of it is just too low and the space inside a vehicle too small. The reflectiveness of the aluminized bubble wrap stuff is the best bet since the space is small it reflects your heat back at you.
