I’m buying a 20ft cargo container to store stuff and need to insulate the roof. The seller charges $350 to bring a contractor in to spray the foam, which seems like a steep price to me. Anyone know the cost of the gear to do this yourself? (Or, I could go to HD and buy about 50 cans of “Great Stuff”)
Thanks a bunch.
Scott.

I don't really know for sure Scott, but I don't think that it's a do it yourself job. I think it takes a truck full of specialized expensive equipment ( I'm guessing 70 to 80 thousand for the rig) not to mention the chemicals it mixes.

*You can buy foam in large sizes (e.g. EnerFoam comes on 10# and 16# dispensers) along with a hose and a wand. Flexible Products makes EnerFoam under license from Dow.
*Thanks Guys.Hey Phil. Great tip. Have you used this stuff? Do you think applicator gives you enough control to lay the foam evenly on a ceiling? (Well.... at least SORTA evenly?)Thanks,Scott.
*Scott, Why only the roof? Here's a link to a source for foam kits. http://www.jrproductsinc.com/catalog.htmlYour 20' container has 160sq' of ceiling area. (I think 8' wide?) At the price of a kit capable of covering that area thick enough to have any effect at all I think you blew more than $350. Although I'm sure you'd have at least $100 worth of fun maybe? Try to keep it out of your hair.If you want to save a buck, how about 5 4x8 sheets of whatever foam you can get locally foamed in place with expanding foam? You can buy the gun and a couple cans of foam on the same site and have a nice tool when you're finished. Cheap is good, Joe H
*Hi Joe.Thanks for the thoughts.Yes, I wondered about why they say to only do the roof, but at least three suppliers told me the same thing.... perhaps the roof is prone to more condensation than the walls when snow sits on top of the container. The walls are vented to allow circulation.I like your idea of gluing 4X8 SM to the roof with canned foam. I think $200 ought to do that.Cheers,Scott.
*Used it a couple of times, but never for a big area. If I were in your position, I'd probably try and cut a deal with an Icynene dealer to take the trailer out to where they're doing a house and get them to do the trailer while they're at it. In any case, the Icynene site http://www.icynene.com/ shows some techniques for smoothing polyurethane foams
