They are used as insulators because they don't conduct heat as well as metals do. Metal will dent and break. Originally they were made of metal and glass with a vacuum between them.

Is a copper penny a insulator?
Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators. So no, a penny is a conductor, not an insulator.
Why are metals good insulators?
They generally aren't. In contrast they are generally good conductors, both of heat and electricity.
Are metals usually used as heat insulators?
NO!!! the properties of metals are that it is a good conducter of heat!!! Please click on the trust button below if this helped.
Is cotton wool a good conductor of heat?
its a good insulator, meaning that yes, it is a good non-conductor. Materials that insulate heat, eg wool, cotton etc, are also by definition good electrical insulators. Good conductors would include most metals, which you may have noticed are bad insulators. you wouldn't wear metal underwear anyway!
What are good conductors called?
They're called conductors. As opposed to insulators, which don't conduct. Metals are typically pretty good conductors.
Do non metals contuct heat?
Non metals do not conduct heat. They have high resistance.They are insulators.Non metals do not have a pool of 'free electrons' (as metals do with metallic bonds). Hence they generally are poor conductors of heat. Nonmetals such as Styrofoam are widely used as insulators. Graphite is an exception as it is a good conductor of heat with its free electrons.Most of the non metals does not conductors because the do not have free electrons. But graphite is a good conductor. Most of the non metals are insulators.
What are physical properties of non metals?
Non metals do not conduct heat & electricity, good insulators, non mileable, high combustivity, low density and light in weight
Are all the non-metals insulator?
No, not all non-metals are insulators. Some are conductive, such as water.
What properties do metals non-metals and semi-conductors have in common?
They generally look metallic but are brittle (not malleable or ductile). Neither good conductors or insulators but they are semiconductors.
Are non metal more electropositive than a metal?
There are two types of conductors 1- Metals and 2- Electrolytes, the compounds which become ionized in aqueous solution or in molten state are electrolyte so metal is a conductor of electricity but not an electrolyte.
Do metals or non metals conduct heat better?
Metals are better conductors and non-metals are better insulators. Metalloids can be either a conductor or an insulator, it depends on the object.
What are uses of nonmetals?
Non metals are used as insulators (poor conductors)
Are metals conductors or insulators?
In general, metals are good conductors of heat and electricity.
Are metals thermal insulators?
omdat je nou eenmaal moet poepen!!
Are non metals good conducters of heat?
no they are not. for example they are used as insulators in double glazing and flasks. if they were good conductors this would not work the heat would pass through.
What elements are the best insulators?
Non-metals (e.g. sulphur) are usually good insulators, with the exception of carbon in the form of graphite. On the other hand, metals are good conductors of electricity in all states of matter.
Are metal gold and copper good heat insulators?
No. Both metals are good conductors of heat.
