Insulation The use of materials to inhibit or prevent the conduction of heat or of electricity. Common heat insulators are asbestos, cellulose fibers, feathers, fiberglass, fur, stone, wood, and wool; all are poor conductors of heat. Good electrical insulators, or dielectrics, include dry air, dry cotton, glass,

Air is a good insulator as it does not let heat to pass through it very easily. The air can be trapped to form a layer of insulation. This insulation can then prevent heat from moving into an object as well as preventing heat moving out of ... This experiment will help you find out which materials make the best insulators.

An electrical insulator resists the flow of electricity. Application of a voltage difference across a good insulator results in negligible electrical current. In comparison, a conductor allows current to flow readily. ... Materials with resistivities higher than 108 ohm-m are usually considered to be good insulators;

Some good examples of insulator materials are rubber, plastic, glass, and wood. The energy of the moving electron is divided so many times that it has little effect on the atom. Any atom that has seven or eight valence electrons is extremely stable and does not easily give up an electron.
