styrofoam cups are great insulators.
some examples are coffe cups, coffe mugs styrofoam cups and coolers.
A Styrofoam cup has the best type of insulation. These are better cups because they have the lowest thermal conductivity.
Styrofoam cups are generally the best at keeping hot drinks warm for a longer period of time. This is because Styrofoam is an excellent insulator, meaning it does not conduct heat well and therefore helps to keep the temperature of the drink constant. Paper cups and plastic cups are also decent insulators, but they are not as effective as Styrofoam. Glass cups are poor insulators and are not recommended for keeping hot drinks warm.
Heat insulators are typically made from made from porcelain rich in alumina or fiberglass.

Red and green are colors, not insulators or conductors. Either insulators or conductors may be red colored or green colored.
porcelain cups
Vacuums make better insulators as convection currents can not form to transport heat energy.
Can you reword the question? Do you mean insulators, instead of conductors?
Insulators.
Because they act as insulators because of their thickness therefore are better conductors of heat :)
Metals are better conductors and non-metals are better insulators. Metalloids can be either a conductor or an insulator, it depends on the object.
