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.
What else can I help you with?
Is air or fiberglass a better 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.
Why a vacuum between a panes is better than air?
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.
Is air a better insulator than fiber glass?
No, fiberglass is a better insulator than air. Fiberglass has a higher R-value, which measures its resistance to heat flow, compared to air. Fiberglass is commonly used as insulation in buildings to improve energy efficiency.
Is air a better insulator then fiberglass batting?
Fiberglass batting is a more effective insulator than air because it traps pockets of air within its structure, preventing heat transfer. Air alone is not a good insulator as it allows for convection and conduction to occur easily.
Air is a better insulator than fiberglass batting?
Air itself is not an insulator; rather, pockets of air trapped within a material act as insulation. Fiberglass batting contains millions of tiny air pockets, which slow down the transfer of heat, making it an effective insulator. In comparison, air alone would not provide the same level of insulation as materials like fiberglass batting.

How are porous materials used as thermal insulators?
actually the insulator is the dead air in the pores a better insulator is vacuum (only radiation) air has conduction convection and radiation air is easier to handle near sea level
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.

Is air or metal is a better insulator?
Air
Why does a double glass window have argon?
Because argon is a better insulator than air
Is air a better insulator then fiberglass batting?
Fiberglass batting is a more effective insulator than air because it traps pockets of air within its structure, preventing heat transfer. Air alone is not a good insulator as it allows for convection and conduction to occur easily.
Which is the best insulator thermocol or air or cotton or aluminium?
Air is the best insulator among the options listed. It has low thermal conductivity, meaning it does not easily transfer heat. Thermocol, cotton, and aluminium are not as effective as insulators compared to air.

Is wood a better insulator than glass?
No. Wood has more air in it than glass, and air is pretty much accepted to be one of the best insulators ever.
Why is air a better insulator than solids?
.air you can breath and if there was no air there would be no things that live out of sea
