If furnished in a thin, polished sheet, aluminum will reflect infrared radiation, as for instance in a so-called "space blanket" which consists of a thin sheet of plastic on which a thin and smooth layer of aluminum has been deposited. In this context, the aluminum can prevent heat losses by reflecting infrared radiation. But if that thin sheet of ...

It really depends on what you are trying to do with it. And thermal "conductors" and "insulators" are not a hard and fast distinction in properties like electric conductors or insulators. Every material just has a certain thermal conductivity, so compared to say diamond, aluminum has low conductivity. With foil, wrapping it with air ...

There are 3 modes of heat transfer: Conduction, radiation, and convection. Conduction is heat simply transferring via contact with its surroundings. Aluminum is a pretty good conductor of heat this way. In this specific mode, the aluminum is worse, it will conduct more than most other things. But, you have to ask yourself, what is it conducting to? Once ...
