Iron, Steel Almonium Etc.
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
materials such as fibreglass are good insulators because they contain pockets of trapped air. :)
An insulator.
It is a good insulator of heat :)
cloth is made up of threads wound together in very tight fashion. In between the two threads there are gaps in which air is filled. It is known that air is bad conductor of heat. So due to this air present, the cloth acts as a good insulator of heat.......

a good insulator of heat keeps the heat in, so you stay warm

insulator is a object that is not a good conductorSo it keeps the heat in.

Dielectric meterials are good insulator materials
A good insulator is good at stopping heat escaping, whereas a bad insulator is not very good at trapping heat and lets it out.
outer electrons of the atoms in a metal are not anchored to the nuclei of particular atoms, but are free to roam in the material. such materials are good conductors.

Most plastic materials have the heat conducting of 0.2-0.5W/m°C. To comparison has steel the heat conducting of 100 W/m°C
