most non metals like polystyrene and lots of plastics
from your mum a friend
Gold, diamond, rubber, and glass are poor heat conductors.
metals are good conductors of heat, i.e. iron, steel,... non-metals are bad, i.e. carbon...
Good conductors of heat, such as metals like copper and aluminum, have high thermal conductivity due to their free electrons that can easily transfer heat energy. Bad conductors, or insulators, like wood or rubber, have low thermal conductivity as they lack free electrons and impede the flow of heat energy. The molecular structure of good conductors allows for efficient heat transfer through collisions between free electrons and atoms, while bad conductors have a structure that inhibits the flow of heat energy.
Substances that don't have the capacity to carry heat are called bad conductors of heat (or insulators ). Substances that have the capacity to carry heat are called good conductors of heat. As for electricity, it is very, much the same.

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.

Good Electrical conductors: All metals, ionic substances (in solution or molten form) Bad Electrical conductors: Water Good Heat conductors: All Metals Bad Heat Conductors: Water
Insulator are bad conductors of heat and electric current. They do not have the property of transferring heat and electricity from one point to another.
