The best thermal insulator is vacuum as in the gap of the thermos bottle. Another god thermal insulators is air (as in closed cell polyurethane foam or double glaze windows, or any gas in closed environment.
insulator. it is not a very good insulator though.
Electrical or thermal? Either way, it's an 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.
it depends how thick the air is!

After the published tables the silica aerogel is a very good thermal insulator.
