Here's why:
* Insulators resist the flow of heat energy. This means they are good at keeping heat contained within a specific area or preventing heat from entering an area.
* Conductors, on the other hand, allow heat to flow through them easily. Examples include metals like copper and aluminum.
Some common examples of insulators include:
* Fiberglass: Used in home insulation to keep heat from escaping in the winter and from entering in the summer.
* Wood: Used in building construction and furniture, providing a layer of insulation.
* Foam: Used in packaging and as insulation in refrigerators and freezers.
* Air: While not a solid material, air acts as an insulator, which is why double-paned windows and insulated walls are effective.
