I recently saw a (temporary) structure for a supermarket which was
undergoing development - it was build from foam filled aluminium panels
about 20 feet by 10 feet - and 5 inches thick. Insulation would have
been good.

And I'll bet it leaked at the joins in short order. It's near impossible
to cope with the expansion such panels suffer in the sun. A small leak in
a warehouse isn't so important as in a house.
