Q & A: is aluminium foil an insulator or a conductor

Follow-Up #1: electrical and heat conduction. Al is an electric conductor, in fact, some wires are made of Al. Its non-conductivity of heat, i.e., its insulation is due to two reasons: One is, as Mike W. said, the tight wrapping of Al around the food stops convective heat transfer, i.e., it stops the flow of hot air from inside the foil to outside.

Is aluminum foil a good insulator of heat? AnswersDrive

As a metal, aluminum foil is also a good conductor of electricity and heat. So why do we wrap food in aluminum foil to keep it warm if aluminum conducts heat so well. Another basic property of all metals is that they are all highly reflective. It also traps pockets of hot air, so that they cannot convect away heat.
