Any insulator - just think what kinds of material are used to protect people from heat: Oven gloves i.e. cotton Pan handles i.e. rubber and plastic Nuclear reactors are surrounded by 10m of water to insulate the thermal heat Asbestos used to be used for insulation The list is endless!
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.
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
Liquids are bad conductors of heat because their molecules are not closely packed together like in solids, limiting the transfer of thermal energy between them. Additionally, the free movement of molecules in liquids also hinders the transfer of heat. This is why liquids take longer to heat up and cool down compared to solids.
Gold, diamond, rubber, and glass are poor heat conductors.

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.
