Some of the best are gases such as carbon dioxide, nitrogen, oxygen, etc. Perlite is extremely non-conductive. Ordinary materials like paper, wood and rubber are also relatively poor conductors. Please see the link.
Objects that conduct heat well include metals like copper and aluminum, as well as materials like ceramics and glass. Fire conducts heat through a process called radiation, where energy is transmitted through electromagnetic waves in the form of heat and light. Other media that can conduct heat are liquids and gases, such as water and air.
insulator.
Things that give off heat are called heat sources or heaters.
Three of these insulators, aka nonmetals, are wood, rubber, plastic, etc
Objects that do not conduct heat well are called insulators. Examples of insulators include wood, rubber, plastic, and ceramics. These materials are poor conductors of heat due to their molecular structure that limits the transfer of thermal energy.
Nothing does not conduct heat. If you are asking for three insulators: a coat, rubber, and plastic.
The ability to conduct heat or electricity is acutally called conductivity.
bad conducters or poor conduct of heat and light energy

They are called good thermal conductors.
Metals can conduct electricity, are malleable (can be hammered into thin sheets), and have a shiny appearance (luster).
Heat insulation is defined as the resistance to the flow of heat offered by a material when it is subject to a change in temperature. Objects that put up a lot of resistance to heat flow don't conduct heat well, and are called insulators. Some examples of insulators are wood, rubber and glass. Things that do conduct heat well don't offer much resistance to heat flow. Many metals fall into this category, such as aluminum, copper, and gold. See the link below for more information on heat conduction.
The substances that don't conduct heat through them are called as 'insulators of heat'. Eg - Plastic, Wood etc.
