Insulators in electricity can be glass or ceramic.Insulators in heating can be polystyrene or fibre panels.
Insulators are materials or substances that do not readily allow the passage of sound or heat. Two examples of insulators are glass and porcelain.
Two materials that act as good insulators are rubber and wool. Rubber is a good insulator because it has a high resistance to electrical current, while wool is a good insulator because of its ability to trap air and prevent heat transfer.
Two other materials that are poor conductors of electricity and good insulators are rubber and glass. Rubber is commonly used in electrical cords and cables due to its insulating properties, while glass is a common insulator in electronics and construction materials.
Two good Insulators are foam and styrafoam
Two types of insulators are plastic (such as PVC or rubber) and glass. Insulators are materials that do not conduct electricity easily, making them useful for electrical applications.
Two examples of electrical materials that are insulators are rubber and glass. Insulators are materials that do not conduct electricity well and are commonly used to protect against electrical shocks or to prevent the loss of electrical energy.

Some heat insulators are fiberglass, polyurethane foam, and polystyrene. Two other thermal insulators used as insulating materials in building construction are mineral wool and cellular glass.
If two insulators are in parallel the current in each insulator equals the voltage divided by that insulator's resistance.
The two main uses of insulators are (a) to prevent short-circuits if two cabled touch, and (b) minimise cross-talk between data cables.
