Insulating the floor of a house on piers
Here in south Louisiana & Mississippi we have a lot of homes that are raised on piers, typically 1-3 ft. It would be nice to insulate the floor from underneath, but there seems to be no good way of doing it.
I am working on a project now where we've taken up the floor, and I would like to install some kind of 4'x8' sheathing underneath the floor joists so that i could then spray closed -cell from above. Is there a product out there that isn't flammable or doesn't cost too much that would work? A well meaning friend suggested stapling Tyvek under the joists, but I don't think that would hold it.

Since drywall has a permeance of 0.02 liter/sec - m at 75 PA is ever possible to have sheathing dry to the interior of the home?
