The definition of an insulator is something that is used to keep heat or sound contained, or something that does not conduct electricity. Soundproofing material is an example of an insulator. A substance that doesn't conduct electricity well is an example of an insulator
These include copper (92), iron (11), water (0.12), and wood (0.03). At the opposite end of the spectrum is a perfect vacuum, which is incapable of conducting heat, and is therefore ranked at zero. Materials that are poor conductors of heat are called insulators
