For Sound, lead or massive concrete; for Heat, fibrous non-conducting materials such as fibreglass and asbestos; for Electricity, ceramics, glass, and plastics.
Note, a vacuum is an almost trivial answer for both heat and sound.

Is quartz conductive?
No, quartz is one of the best insulators there is.
What are good insulators?
Good insulators include glass, styrofoam, plastic, wood, rubber, cloth, air, glass, and etc. It really depends on what you want to use it for. For example, fiberglass or styrofoam works the best as heat insulators. And rubber or glass as electric insulators.
What materials make the best conductors and insulators?
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.
What the best conductors and insulators?
Most Metals are the best conductors. Like, silver. The best insulators are plastic, like glass. These materials are some of the best conductors/insulators because of their ability/inability to conduct electric current. Electric current is the flow of electric charge through a medium. Insulators have a high resistance and do not allow electrons to flow easily through them. Conductors have a low resistance allowing electrons to flow freely. In order to say which is the best or worst conductor you can check a resistivity table(typically measured in ohms). Be careful to look at the temperature of the material because that can change the resistivity.
Why are blankets good insulators?
Blankets are defined to be insulators.
What are of the best insulators of cold?
Styrofoam

What are the best examples of insulators of electricity?
Plastic, rubber, glass, air...
What substances are the best insulators?
Usually nonmetals. Rubber, plastic, wood, cloth, paper, Styrofoam, tinfoil (to reflect the heat.)The most common insulator for electricity is plastic.
What do you call poor conductors?
Insulators.
What materials make the best conductors and insulators?

What items are insulators and conductor?
Conductors are materials that allow electrons to flow easily through it. Metals are the best examples of conductors. Insulators to the opposite; they don't like letting their electrons flow. Glass, rubber, and wood are some examples of insulators.
What is the five best insulators of heat?
foam,wool,wood,cork,and,fur
