Re: painting roof white &/or radiant barrier insulation & insulating AC attic cooling du
There are definitely differences in proper insulation practices between hot and cold climates.
The foil backing on fibreglass was intended to reflect heat back into a warm room in winter. It is not a vapour barrier at all. Nor is it contiguous so it doesn't work as a radiant barrier either. In fact it's pretty much been dropped for use up here too.
Got to use what works right for the particular job. And that's pretty much a universal truth.

Ohm's Law: Amps = Volts / Ohms
Power Formula: Watts = Volts * Amps
