Shredded paper is a good insulator because it creates a lot of dead air space. The layers of air held in by the paper is what has an insulating effect.
it is good heat insulator, as it has air in it. as air is a good insulator of heat, the sponge, which has lots of pockets of air also becomes a good insulator
An empty space is called Vacuum.
it depends what type of insulator youre talking about. wood is a good thermal insulator and rubber is a good electrical insulator A perfect vacuum is the best insulator.
Yes. Polystyrene is a good insulator.
Radiation can travel through empty space. The radiation in question is electromagnetic waves.

Outer space is NOT a good conductor because their is no matter in space. Good conductors hold heat well and since their is no matter in space, it cannot be a good conductor. Space has to be a good insulator because it can't hold heat.
the insulator its made up from stops the heat escaping. Thats why they are good. :)

A material that insulates, especially a nonconductor of sound, heat, or electricity. A device that insulates another material or space from something. For instance glass is a good insulator from electricity. The electrons will not flow through glass. Cork is a good insulator from sound. Sound waves have a hard time passing through cork. Wood is a good insulator from heat.

All the isolated gas bubbles slow down transfer of heat. It also helps that there is very little material to hold on to much heat so the heat that does transfer through it is very low and also There's lots of empty space in between all the bubbles and because it's so light people use it as an insulator.
