I have been wondering about that. I have also heard that spray foam could cause the tin to rust out in the long run if any water gets in there, because the spray foam will trap it there. It doesn't really sound like there is any sure fire way to prevent rusting from happening, so I think the spray foam will be the best route.
I don't know why I didn't think about that, I'll just scroll through my contacts list and call Lee up I think if I had his number, he would block my calls after about the 100th time asking to come hunt
I would imagine it would depend on if it's closed cell or open cell foam. I'm not familiar with metal buildings as homes, so I have trouble envisioning the insulation process. I know you want the home to be able to breathe. Balancing water from getting in, but providing a good solution for it to escape when it needs to. I don't think you would want closed cell foam on the interior walls in your climate, though.
From my understanding, if you use spray foam insulation, you would spray the entire shell, roof and all. I have blown in wet cellulose insulation. They insulated the walls first, then once I had the drywall up, they came back and blew it onto the ceiling. This will allow the house to "breathe". I wouldn't thing you would want it sealed up tight as a drum because you would get all sorts of condensation. I'm not an expert though.
My mom and stepdad currently live in the barn on the left. It's awesome. They have parts of it framed off inside. Full kitchen, bath, etc. Its all temporary while they are building the house. Once the house is built they will take out all the appliances, cabinets, etc, and sell them, and the barn will become a garage.
