Pro Tip 1/3Types of Insulators
Insulators can be classified by what they resist such as heat, electricity, or sound.
Glass wool is a popular thermal insulator in buildings.
Pro Tip 2/3Insulator Materials
Common insulating materials include rubber, plastic, glass, and wood.
The plastic coating on wires acts as an electrical insulator.
Pro Tip 3/3Insulation Effectiveness
The effectiveness of an insulator is measured by its ability to resist the transfer of a particular form of energy.
A double glazed window is a more effective sound insulator than a single pane.

Otherwise you'd be getting zapped all the time. Conductors like metals and salt water tend to have loosely bound outer electrons, which can easily flow between molecules. On the other hand, insulators like plastics, rubber and glass

In conductive materials, electrons flow around atoms, forming an electric current. In contrast to insulators, the electrons in conductors are weakly bound and flow easily. A resistive touchscreen has two layers.
