It would satisfy me if I you had some examples, but I don't think that
you know the answer for sure. If a vacuum is a good insulator (like a
vacuum thermos) and a perfect vacuum, as far as I have been able to
read online, is a perfect insulator. Electricity and heat pass from
object to object, not from space to space. Please point out any source
you can find to the contrary. What little I find agrees with vacuums
being insulators of heat and electricity.
