Bob hit on the main reason for wrapping. Not so much for heat in the
dead of winter but a uniform temperature in the hive on both ends of the
season.

Both because of uniform temperatures in the hive.
I do not wrap, but if you do it does not take much, usually tarpaper is
enough. Tests showed more substantial wrapping made little difference in
winter survival or spring vigor (the Hive and the Honey Bee). I know two
beekeepers in my area that wrap with tarpaper and one has excellent
success overwintering, the other has more winter kills than those that
do not wrap. The beekeeper's summer and fall practices make a bigger
difference in overwintering and bee vigor than wrapping.
