Conductors are materials that will allow electricity to flow through them. Materials that contain 1, 2, or 3 valence electrons are good conductors. Some examples of good conductors are gold, silver, aluminum, and copper. Insulators are materials, or combinations of materials, with a high number of valence electrons (5, 6, 7, and 8). Examples of good insulators are porcelain, glass, air, and rubber.
Insulators: wood, plastic Conductors: Copper, Gold

rubber or plasic is used as an electical insulator to cover wires to prevent against elecric shock. Gloves are used over hands as a thermal insulator to prevent burns while holding hot objects. insulated footwear are used when working in an enviorment dealing with many exposed live wires.
Thermal insulators have insulating capabilities. This means that they do not have any aspect that allows them to conduct thermal energy.
some examples are coffe cups, coffe mugs styrofoam cups and coolers.
There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.
A thermal insulator is a material which does not allow the passage of heat; therefore the particles which make up the material are not free to move. Plastics, wood, and air can be thermal insulators providing that NO thermal currents can develop. Air in trapped clothing, air between the panes of glass in double glazing are examples, as are a lid to cover the coffee mug.
An insulator is a material that does not allow a transfer of electricity or heat energy. Materials that are poor thermal conductors can also be described as being good thermal insulators. Feather, fur, and natural fibers are all examples of natural insulators

A thermal insulator slows or stops the passage of heat through it.

The opposite would be thermal conductors, as are used on cooling radiators.
