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.
Substances that don't conduct heat are called 'Non-Conductors'
All metals conduct heat. Some of them conduct it better than others, but there aren't any that don't conduct heat at all.
aluminum foil
Wood, and coal.
insulators
conducters
Graphite
Insulators
Conductors and heaters
Things do not conduct cold, they conduct heat. Being a metal aluminum foil is both a good conductor of heat and electricity.
Germanium is a metal that does conduct heat, but does not conduct heat as well as other metals. This makes it a semiconductor.
Non-metals tend to not conduct heat
No because there is nothing to conduct heat
conduct electricity, conduct heat, melt
Nothing does not conduct heat. If you are asking for three insulators: a coat, rubber, and plastic.
No they do not. They keep the heat in. In other words they are Insulators.
Conductors and heaters
Yes. Basically every metal conducts heat
The ability to conduct heat or electricity is acutally called conductivity.
bad conducters or poor conduct of heat and light energy
All metals conduct electricity.All metals conduct electricity.All metals conduct electricity.All metals conduct electricity.

Technically, everything. Any amount of matter will conduct heat as a matter of molecular vibrations. However, heat conduction increases with density and delocalization of bonds (metals are the best conductors, followed by some forms of graphite, then probably some organic molecules, then other molecules, then salts, then lastly rocks and such).
They are called good thermal conductors.
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.
