Plastic foam, fur, and feathers are bad conductors of heat because they have a lot of air pockets trapped within them. Air is a poor conductor of heat, so materials that have a high amount of air trapped within them are also poor conductors of heat. This trapped air creates a barrier that prevents the easy flow of heat, helping to insulate the object or organism.
Aluminum is the best conductor of heat among the materials listed. Glass, plastic, and foam are poor conductors of heat in comparison to aluminum.
Plastic foam is a good insulator because it contains air pockets that trap heat energy and reduce the transfer of heat. These air pockets slow down the movement of heat through the material, making it harder for heat to escape, thereby reducing heat loss.
Materials such as plastic foam, feathers, and fur are poor conductors of thermal energy because they have a low density and consist of many small pockets of air. Air is a poor conductor of heat, so these materials trap air within their structure, reducing the ability for heat to be transferred through them efficiently. This trapped air acts as insulation, helping to keep heat from being conducted away from the body.
Window glass is a better conductor compared to a plastic foam cup because glass is a solid material with higher thermal conductivity, allowing heat to pass through it more easily. Plastic foam cups have air pockets in their structure which act as insulators and reduce heat transfer, making them poor conductors.
Materials that are poor conductors of heat are Plastic and Wood "example."

The answer I found was : In foam there is a large gap between the conduction band in atoms making up the foam. or The atoms of some materials have no free electrons in their outer orbits. These electrons are busy doing other jobs, like being shared in the orbits of two adjacent atoms. They are so closely held that it is very difficult to pull them away. Most compounds of carbon and hydrogen are like this. Plastics, whose molecules are made from long combinations of carbon and hydrogen atoms, have few or no free electrons. This means that plastics are poor conductors of electricity (and they are also poor conductors of heat).
Yes, metals are better conductors of heat than plastic.
Foam cups are typically insulators because they are made of Styrofoam, which is a material that does not conduct electricity well. This means that foam cups are not good conductors of heat or electricity, making them effective at keeping hot drinks hot without transferring heat to your hand.

Water in a glass cup will typically freeze fastest. Glass is a good conductor of heat, allowing it to transfer heat away from the water quickly. Plastic and styrofoam are poor conductors of heat, so they insulate the water and slow down the freezing process.
