Insulator or conductor depending on the circumstances. Aluminum foil conducts heat, but it cuts off air flow and reduces evaporation of fluids. Aluminum foil reflects and thus minimizes radiation transmission. With foods it is more useful as an insulator. It also acts as an insulator on windows. But, aluminum is definitely a good heat conductor.
Conductor.
insulator
Aluminum foil can be use as both insulator and conductor. It can wrap and trap air inside cause thermal insulating effect but in other hand, aluminum itself is a conductor for evenly distribution of heat throughout the food. Aspect of substance fabricated is different from an insulation conduction aspect of a substance.
What we usually refer to as tin foil is almost always aluminum foil. Aluminum is a very good conductor of heat, and aluminum foil makes a very poor insulator. The exception might be in the case of radiant energy, which it reflects well, and even better when it is polished.
Foil is considered to be a good insulator since it has the ability to reflect radiation. However, aluminium foil is commonly used as a conductor and not an insulator.
If I had to choose the best insulator out of steel wool, aluminum foil, cotton and bubble wrap, I would choose the aluminum foil.
yes it is because it traps the coolness inside.
What is floil? Do you mean aluminum foil? If so, metals conduct heat fairly well.

i think it is a insulator

it is actually a conductor of heat and electricity. you can check by puting some foil on a piece of toast on a really hot day and if you wait a while it will turn into crispy toast.
no

Insulator
Aluminum is a conductor of thermal energy and electrical energy.
no because aluminum foil is a metal
yes
