What makes a good thermal insulator and why?

Materials that are good conductors of thermal energy are called thermal conductors. Metals are very good thermal conductors. Materials that are poor conductors of thermal energy are called thermal insulators. Gases such as air and materials such as plastic and wood are thermal insulators.

Also to know is, what type of material makes a good insulator?

Some common insulator materials are glass, plastic, rubber, air, and wood. Insulators are used to protect us from the dangerous effects of electricity flowing through conductors. Sometimes the voltage in an electrical circuit can be quite high and dangerous.

What fabric is a good insulator?

Wool fibers are woven tightly together, and are much thicker than other materials, such as cotton. They don't allow much heat to escape, which means they are great insulators. Fabrics like cotton and lace are breathable fabrics, meaning they allow a great deal of heat to escape.
