The only foam that is close cell is XPS foam.
Spray foam will work but even the best application is only 90% close cell...which means that it can absorb 10% water so it needs to be covered.
A buddy of mine has spayed it for year. I would tell him that 2lb foam shouldn't spay a roof.....move ahead 10 years...they changed the BC building code so only 1/2lb foam can be sprayed in a roof which allows water to pass through.
How about skirting made with snow, hay, fabric or boards.
