There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.
Rubber, Styrofoam, air pockets, cloth, plastic

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
Usually nonmetals. Rubber, plastic, wood, cloth, paper, Styrofoam, tinfoil (to reflect the heat.)The most common insulator for electricity is plastic.
Ideally, they should be constructed of light weight materials like reinforced aluminum
Anything that isn't a conductor. Insulators don't conduct charges very well because their electrons cannot move freely.
Ideally, they should be constructed of light weight materials like reinforced aluminum
Rubber Wood
A material or an object that does not easily allow heat, electricity, light, or sound to pass through it. Air, cloth and rubber are good electrical insulators; feathers and wool make good thermal insulators.
