    In theory, that's probably true.  In my non-scientific experience with 
two garages, they are both substantially cooler in summer and warmer in 
winter than they were with uninsulated ceilings.  Neither have any A/C, 
and the one with heat noticed a drop in heating costs.

    For a about a year after I did mine, I kicked myself everyday for not 
doing it the week I bought the house.  YMMV.
