No. If you can get it, vacuum is the best insulator.

Is air or fiberglass a better insulator?
i hope air is better than fibre glass
Is glass a better insulator than styrofoam?
no
How do ice box trap heat and prevent it from escaping?
Insulation mainly... basically foamy material. Nothing is a better insulator than lots of tiny bubbles - except a vacuum.
Is styrofoam a better insulator than wood?
Yes
Is cardboard a better insulator than styrofoam?
No, it's not

Yes

No, it's not
Is a material with a lower R-value a better insulator than a material with a high R-value?
No. A higher R-value is a better insulator.
How does plastic act as a heat insulator?
For practical purposes, air is an excellent thermal insulator. So any material with lots of entrained air (and through which the air cannot freely pass) will be a good thermal insulator. The remaining conduction path through the material is along the filmy walls of the bubbles, and this path will be long and of small cross-section. A vacuum is of course a better thermal insulator, but there are practical difficulties in making a foam of vacuum bubbles. And there are some materials (some CFC gases) which are better thermal insulators than air, but once again there are difficulties in keeping these gases entrained in the foam bubbles.
Air is a better insulator than fiberglass batting?
Fiberglass insulation is better than air, but closed cell foam is better.
How can you determine if foam is a better insulator than paper?
yes you can test it under a lamp and see the temp. for the foam and paper and if one has the lowest than that's the better insulator!good luck!
Is plastic a better insulator than metal?
No, it is not. Metals conduct heat much better than most plastics. However, if the metal is used as a reflector of radiated heat, it will insulate better than plastic would.
Why does the glass on a window pane feel cooler to the touch than the wood frame surrounding the glass?
Wood is a better thermal insulator than glass, which is easily cooled.
