What both of you guys should use is a product called thermax or Rmax.
It's a dense non-flammable styrofoam, bonded to an aluminum foil face or
white vinyl face. Standard thickness in 1/2" multiples from 1/2" to
about 6". Standard sizes 4'x 8', 10', 12' etc. Self supporting and
strong, and no insulation needed above.
This product is generally used underneath built-up flat roof systems for
both insulation, and when manufactured in a "cant", to provide drainage.
Also used for field construction of huge freezer boxes.
When we buy it, it generally is in excess of 100K SqFt at a time, so a
garage ceiling
volume is the stuff we throw in the dumpster at the end of a job.
I would start at Home Depot, or call some local big industrial roofers.
Might luck out and get the excess.
