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.

Blackout curtains are an effective way to insulate glass, cutting heat loss by a fourth. Energy film is another, though a bit more expensive insulator. This film has increased transparency and combining its benefits with blackout curtains decreases energy costs significantly.

Individuals replacing insulated glass should complete the project themselves, if possible, since hiring a professional to make this replacement is often very expensive. According to The Family Handyman, this project only takes about one day to complete.

Antique insulators can be very valuable. These insulators were used on telephone and telegraph poles beginning in 1844 and were usually made of glass or pottery materials. Threadless insulators made between 1850 and 1870 are highly desired by collectors.

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.

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.

Factors involved in the value of old bottles vary. Rare bottles may fetch higher prices, while bottles that exist in abundance are seldom worth more than their material value. Other important factors include color, condition and age.

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.

The best material that serves as an insulator is glass because of its high resistivity, states Georgia State University or GSU. The photons present in glass do not have enough energy to close the gap between the valence electrons and the conduction band.
