Items that make good heat insulators include fiberglass, air, iron fibers, Polystyrene foam and thin plastic films, according to scientists at the Argonne National Laboratory. Some insulators work by having pockets of air to spread out heat. Other insulators reflect light away and thereby insulate a

Oil, fur, silk, wool, rubber, glass, plastic, wood, paper, wax and ebonite are good insulators. Insulators are substances with tightly bound outer electrons and heavily resist the flow of electrons. Most nonmetals are classified as insulators.

Materials that make good insulators do not have the ability to conduct electricity, such as glass. They insulate because they do not have enough free atoms to conduct electricity.

The most accessible and affordable home insulator is rolled fiberglass, and the most effective insulator is closed cell foam, according to HGTV. Cotton batts are a comparable option.

Some examples of insulators are glass, plastic and rubber. Insulators block the flow of electricity through them due to the stability of the electrons surrounding an atom. However, the electrons in some insulators, such as glass, move more freely in extremely high temperatures and can become conduct

Insulation slows or prevents heat, sound, electricity, mechanical vibration or radiation from coming through walls. There are four types of insulation: heat insulation, sound and vibration insulation, electrical insulation, and radiation insulation.

Fiberglass, rock wool, loose fiber and reflective foam are some of the many types of insulation available. The style of the insulation, such as rolls or boards, can help determine where the insulation should be used in the home.

Home insulation is vital to saving energy, cutting costs and helping the environment. Caulking to attic insulation to finding places that need more insulation are efforts that can keep a home and wallet comfortable.

Installing heavy curtains or reflective film on windows, sealing window and door cracks, and properly sealing a chimney are good ways to insulate a house. Have a professional install attic insulation.

Air is a good insulator because its molecules are very far apart. This makes it difficult to transfer heat, according to Dr. Ken Mellendorf, a physics professor at Illinois Central College.
