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.
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.

Well, honey, aluminum foil is a conductor, not an insulator. So, if you're looking to wrap up your leftovers and also conduct some electricity, aluminum foil is your go-to. Just don't go sticking it in the microwave unless you want a little light show to go with your reheated dinner.

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.
Insulator
Aluminium foil is a conductor of electricity. Due to its metallic properties, it allows electrical currents to flow through it easily.

Aluminum foil is a type of metal and it is generally a good conductor of heat. However, compared to other metals like copper and silver, aluminum foil is not as good of a heat conductor. Copper and silver have higher thermal conductivities compared to aluminum.
The reason that some materials are good conductors (of electricity) is because the outer electrons of the atomic nucleus are easily pulled away by an electric charge and if you keep applying that charge (such as with a battery) a current will flow. A good conductor is just the same as a bad insulator.
