Though I'm sure they've changed it, the stuff I'm familiar with got a lot of
its oomph from vermiculite - see the talc/asbestos dissertations referenced
above. Not to mention you can _always_ heat a smaller space for less than a
larger.

Interested in methods that others are using for working during winters
in metal quonsets that don't have permanent insulation.

I'd guess you wouldn't want to get this
elaborate, but what about that spray
foam insulation that used to be applied
to walls and ceilings? Don't know if
it's used anymore. I'v heard that a
quonset hut is very efficient to heat
if well insulated.
