Trapped air makes a good insulator.
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
you did not show me any thing
a poor thermal conductor

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.
A nonmetal would make a good insulator.
rubber
the insulator s metal must has fully filled orbital without any free electron

i think it does because it sure doesn't make a good conductor.
