Generally, things that feel cold to touch (in a normal temperature room and no heating applied to them) are good conductors of heat (metals for example).
Poor conductors tend to feel neither hot or cold under normal conditions (wood for example).
Conductors- Most types of metal. Copper and Aluminium are used these days. Silver is a very good conductor but it is expensive. Insulators- rubber, plastic and wood are good insulators in the solid state.
plastic, glass and rubber
In electricity, Insulators help insulate electric charges. Conductors conduct the electric charges and make them into electricity.
Assuming you mean an electrical conductor, No. To be a conductor, a material must have free electrons in the conduction band of the atoms. Metals have free electrons intrinsically in these bands, and so make great conductors. If you mean heat conductors, the answer is also no. Some objects are insulators of heat.
The conductors carry the electricity around the circuit... the insulators make it safe for people to operate the switch without being electrocuted.

There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.
The conductors carry the electricity around the circuit... the insulators make it safe for people to operate the switch without being electrocuted.
On the contrary, insulators have higher resistance than conductors. Resistance refers to resisting a flow of electricity, making it more difficult for electricity to flow. Conductors conduct electricity, they make it easy for electricity to flow. Insulators prevent the flow of electricity.

Usually nonmetals. Rubber, plastic, wood, cloth, paper, Styrofoam, tinfoil (to reflect the heat.)The most common insulator for electricity is plastic.
What materials make good conductors
To make electricity go where you want it to go, so it will do what you want it to do, you have to provide a pathway along which it can travel, made of conductors, and barriers around that pathway, made of insulators, to keep it from leaking out of the desired pathway.
Most plastic combs (like for combing your hair) would be classified as insulators. All materials conduct, however, the amount of voltage (i.e. electrical pressure) required to make a material conduct generally cause us to classify materials as either: 1. Conductors (e.g. copper, gold) 2. Insulators (e.g. air, mica, glass, Teflon - http://en.wikipedia.org/wiki/Electrical_insulation ) 3. Semi-conductors (e.g. Silicon (Si) and germanium (Ge) )
