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.

Why are cool boxes lined with expanded polystyrene?

ANS1 They are lined with it because expanded polystyrene is made up of roughly 95% air. This creates a barrier between the inside of the cooler box and the outside temperatures. Essentially it regulates the inside and outside temperatures. ANS2: 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.

Will lined curtains help keep out heat and cold in addition to blocking the sunlight?

Lined curtains will help keep out the elements to a certain point, if you have a light colored fabric then the heat and light from the sun will be reflected off, also if you keep the blinds closed then you can prevent alot of heat from escaping in the winter.
