Is water an insulator?
Well actually, pure water is an excellent insulator and does not conduct electricity.
The thing is, you won’t find any pure water in nature, so don’t mix electricity and water..
Is wood or rubber a better insulator?
Because they are poor conductors of heat and electricity. Glass is not a good insulator for heat transfer. This is why double panes sealed with air or argon gas between them is used in houses. While wood and rubber are poor electrical insulators, they can burn or melt when subjected to high heat.
Is a vacuum a perfect insulator?
With its complete lack of atoms, a vacuum is often considered to be the best known insulator. For this reason, vacuums are regularly used to reduce heat transfer, such as in the lining of a thermos to keep beverages hot or cold.

What is the most effective insulator?
Aerogel is more expensive, but definitely the best type of insulation. Fiberglass is cheap, but requires careful handling. Mineral wool is effective, but not fire resistant. Cellulose is fire resistant, eco-friendly, and effective, but hard to apply.
What are 5 insulators?
Is bubblewrap a good insulator?
Bubble wraps serve as a good insulator because of its design which has small air pockets. Because the base material for bubble wraps are plastic, it heats up quickly, and so bubble wraps serve as good insulators. Bubble wraps are also best suited for greenhouses.
