Trapped air is the best, like a thermal flask.
Water is pretty good, as well as fabrics in some clothes.
Plastic is an insulator.
Trapped air makes a good insulator.
Glass is a good insulator because it is a poor conductor of heat and electricity. Its structure makes it difficult for heat to pass through, trapping heat inside a space effectively. Additionally, glass has a low thermal conductivity, which means it is slow to transfer heat, making it a good insulator material.
Styrofoam is a good insulator because it has a low thermal conductivity, meaning it doesn't easily transfer heat. This property makes it useful in applications where thermal insulation is needed, like in packaging or construction.
Oil is an insulator. It does not conduct electricity well due to its low electrical conductivity, which makes it a good material for insulating purposes in various applications.
Ceramic is a good insulator. Its strong resistance to heat and electricity makes it suitable for use in a wide range of applications where insulation is needed.
Plastic is an insulator.
Trapped air makes a good insulator.
If the the number of electrons on the shell are stable.
Rubber, Plastic, Wood, Cloth, Paper, Styrofoem, Tinfoil.

The most common usage of (thermal) insulation of heat are Ceramics.
insulator
it depends what type of insulator youre talking about. wood is a good thermal insulator and rubber is a good electrical insulator A perfect vacuum is the best insulator.
An electrical insulator is a material whose internal electric charges do not flow freely. Rubber, glass, paper, and Teflon, which have high resistivity, are very good electrical insulators.
Styrofoam is a good insulator because it has a low thermal conductivity, meaning it doesn't easily transfer heat. This property makes it useful in applications where thermal insulation is needed, like in packaging or construction.
