: Two styrofoam coolers, one inside other, a hole cut out for entry/exit,
: a layer of blankets with the microwavable heating "frisbee" (forget the
: name) under them. Do I need extra insulation between the walls? I can
: even cover the entrance with hanging strips of plastic the way they
: have in some grocery store freezers.
Does anybody know if styrofoam is sufficiently wind- and water-proof
against harsh high velocity drafts or do I need to line it with
plastic?
