What are bad insulators?

Answer 1

Anything metal is a bad insulator. Especially copper, in fact, most metals are conductors!! Anything metal is a bad insulator. Especially copper, in fact, most metals are conductors!!

Answer 2

It we think about it, we'll realize that good conductorsare bad insulators. If we're talking about heat or electricity, metals are bad insulators as they pass electric current or thermal energy pretty well compared to other materials.

Answer 3

Anything that will:

* allow the energy you're trying to insulate against to flow

* be hard to work with

* be too expensive to use

* be dangerous to install

is a bad insulator.

For instance, a rock would stop electricity from flowing, and it would slow down the flow of heat. But it's hard to drill a hole in a rock to feed a wire through it, so it would be a bad electrical insulator.

Asbestos, which provides great resistance to both heat flow and electrical flow, used to be the best insulation you could possibly install...until we learned how dangerous asbestos is to be around. Asbestos, therefore, is a bad insulation.

Steel, as you can probably figure out, is a terrible insulator if you're trying to stop heat or electricity. But if the energy you want to stop is mechanical - road vibrations, for instance - you can make a good insulator called a coil spring from steel.

Gases like air and argon make good thermal insulators if you can confine them in an enclosed space, like between two sheets of glass, and excellent vibration insulators if you put them in an air bag. But just in the atmosphere, air isn't that great.

Answer 4

Any metallic material would not make a good insulator.
