For many years fiberglass was used as an insulator in homes. Technology over the years has introduced newer products for insulation, and one of the most popular types now is a spray foam insulation.
insulator, conductor and semiconductor
insulation materials
Insulator is a material that resists the flow of electric current. materials such as glass, paper or Teflon are very good electrical insulators. These materials are used to support or separate electrical conductors without passing current through themselves.
Insulator
Since elastic is rubber and rubber is an insulator, then yes, elastic is an insulator.
It will depend on the specific book and what materials have been used to create it. In most cases, a standard bound book of paper and standard cover will be an Insulator. With specific inks or metallic materials it could be a conductor.
No, glad wrap is not a good insulator. There are other materials used in which are much better at insulating than glad wrap, such as aluminium foil or wool.
Flax is an insulator because it is a natural fiber that does not conduct electricity well. It is used in applications where electrical conductivity is not desired, such as in textiles or insulation materials.

Dielectric meterials are good insulator materials
A good insulator in a house effectively reduces heat transfer, keeping indoor temperatures stable and energy bills low. Materials such as fiberglass, foam, and cellulose are commonly used due to their low thermal conductivity and ability to trap air. Additionally, proper installation is crucial to minimize gaps and ensure maximum efficiency. Overall, a combination of high R-value materials and meticulous application contributes to effective insulation.
A sharpener is not an insulator. Insulators are materials that do not easily allow the flow of electricity through them, while a sharpener is typically made of materials like metal or plastic which are conductive materials.
