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.

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

Good insulators are materials that do not allow heat to pass through them. They are also materials that either slow down or do not allow transfer of electricity through them.

Cloth can be a great choice for green and chemical-free insulation in the home. Using cloth as an insulator keeps fabric scraps out of the landfill and minimizes exposure to harmful chemicals common in modern insulation.

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.

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.

Glass is a good electrical insulator because the electrons in the glass are tightly bound to the atoms and do not transfer easily, thus keeping electricity from moving through the glass. Conversely, good electrical conductors contain electrons that move freely.

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.
