Is Aluminium foil a good insulator?

Aluminum. Aluminum is a shiny, silver-like metal, numbered 13 on the periodic table of elements. It is a conductive metal, as it allows for the easy flow of electrons. Interestingly, while aluminum is electrically-conductive, it is a good insulator of heat.

Is plastic or metal a better insulator?

A metal block is a better conductor and so energy is transferred more quickly to that ice cube. … Plastics are good insulators so, even though the plastic is at a lower temperature than your fingers, little energy conducts to the plastic and it feels warm.
