Thermal insulator
Insulation
Heat needs something to "flow" through. In a vacuum it will not have a medium to travel through and so heat cannot flow across a vacuum. Radiant heat will travel through a vacuum but here it is the light energy that is passing through the vacuum, not the heat energy.
insulator
In that case, energy will flow quite naturally, as a heat flow. Heat can flow through three methods: conduction, convection, radiation.
Light heat or sound

insulator
The flow of heat energy through materials.

Conductor
The flow of thermal energy is called heat transfer. It is through the various means of heat transfer that thermal energy moves from one place to another. Heat moves from where it is hot to where it is not. Always. Think it through and it will make perfect sense.
