WebReasons why wood is a good insulator: Wood works well as an insulator because there is a void (vacuum) in it. Vacuum is an insulating medium that does not conduct electric current, so it can serve as an insulator. There are no free electrons in a wood through which electricity passes. Hence, it has high resistance.
