I am coming to the conclusion that I will probably avoid spray foam. Reasons:
1. Spurious or not, health concerns are real and they never really stop off-gassing.
2. People use it to fill voids but according to some manufacturers it never cures under such conditions.
3. Horror stories about uncontrolled expansion resulting in bulging body panels. Maybe that wouldn't happen to me, but maybe it would.
4. That you have to wear a safety suit and masks to apply it.
5. It's really permanent. If you screw up, you are screwed.
6. Sounds messy.
7. My wife has had cancer twice and is very cautious about environmental exposure to chemicals.
8. If carbon footprint and environmentalism is an issue, it seems odd to use a petroleum-based product to cut down on petroleum i.e. energy useage.
9. Reports of rust and metal degradation. Illustrations of this in THIS forum.
Given the above-stated concerns about foam insulation, especially spray foam, I am wondering whether there is a cellulose-based automotive insulation. Maybe something in pads, foil-backed? What I have stumbled across so far is polyester. My wife is even thinking leave the interior uninsulated - and I know there are those who prefer the raw walls - and hang wool blankets on the walls when used for camping. Simplicity.
