You can also rolled insulation in the ceiling.

Getting it to stay up is the problem. It's just a bare, tin ceiling --
no "joists" to attach the stuff to.

I also strongly recommend
ceiling fans- a few cheap ones from Home Depot will do wonders

Yeah, once the ceiling is insulated, that will be good. I also want to
add better lighting. Right now I've got three 500 watt spot/area
lights, which are better than the single 60 watt bulb the hangar came
with -- but not much!

Now, all I need to do is figure out is how to get an electrically heated
ramp, and put a hot tub in the hangar.

I've got only electric, no gas, so we're stuck with portable heat
options. And I don't think the hot tub would work well with a torpedo
heater! (It would sure be cool in your hangar, though...)
