I would like to us a used (lightly) shipping container to build a honey house. My current shop is one of those 'roofing as all surfaces' metal contraptions which is completely uninsulated. Needless to say, it gets quite warm during extracting season when I have to keep the door closed to keep the bees out. I've clocked it at 109 degrees F and 98 percent humidity. It's great for getting honey out of combs, but no fun otherwise. It's also very cold in winter when I'm working on frames and boxes, but at least it keeps the wind off.
So I'd like to have a better one which will also serve as my wood shop (building my own boxes) and a platform for a mess of solar panels. Most of all, I want to be able to take it with me when I move.
I've seen a number of methods of insulating, from the usual wood framing with fiberglass batts to fancier things like foam boards and spray foams and such. I don't like fiberglass and given space limits, it won't provide much bang for the space it takes up and I'd like it to be as efficient as possible. Another one I've seen was using Icynene, open cell foam filling in wood framing. This option looks really good, but with winters around here at least occasionally able to form ice on the inside of windows, I wouldn't want water migrating through and rusting where I can't see. Polyurethane foam would probably be the best option but it is expensive. My brother has done two with foil faced foam boards on all sides with plywood on top and they seem to work well, but how would he know if moisture were getting through?
Has anybody tried this? Any ideas?
