Air is a poor conductor of heat. Likewise, the thin walls of the bubbles of polystyrene are poor conductors. Bubbles of air, rigidly fixed in a polystyrene matrix, cannot transfer heat by convection. That leaves reducing radiation as the only unaddressed mechanism for controlling heat loss. Its low cost and ability to be molded makes expanded polystyrene an economical choice for an effective insulator.
