No. If you can get it, vacuum is the best insulator.
Fiberglass is a better insulator than air because it has the ability to trap air pockets within its fibers, which reduces heat transfer. This makes fiberglass a more effective thermal insulator compared to the air itself.
A vacuum is a better insulator than gas because there are no particles in a vacuum to transfer heat through conduction or convection. Gas molecules can transfer heat through conduction and convection, making them less effective as insulators compared to a vacuum.
A vacuum is a better insulator than air because it lacks particles to conduct heat through conduction or convection. Without particles present, heat transfer is limited to radiation, which is less efficient. This makes vacuums good insulators for maintaining temperature, as they prevent heat loss or gain.
How would you fit a vacuum between window apnes :) Jokes aside, neither heat nor cold can pass through a vacuum, so you can't lose or gain heat. There's nothing there to transport the thermal energy, whereas in air, there is.
Yes, styrofoam is a better insulator than wood because it has a lower thermal conductivity, meaning it is better at trapping heat and preventing it from escaping. Additionally, styrofoam is more resistant to moisture compared to wood, which can affect its insulating properties.

No. A higher R-value is a better insulator.
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!
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.
Wood is a better thermal insulator than glass, which is easily cooled.

Theoretically yes because glass is a poorer thermal conductor than steel.
No, cotton is not a better insulator than aluminum foil and tissue paper. Aluminum foil is a good insulator as it reflects heat, while tissue paper acts as a thermal barrier. Cotton, on the other hand, is not as effective of an insulator because it does not have the same reflective or thermal barrier properties.
Because argon is a better insulator than air
