What we usually refer to as tin foil is almost always aluminum foil. Aluminum is a very good conductor of heat, and aluminum foil makes a very poor insulator. The exception might be in the case of radiant energy, which it reflects well, and even better when it is polished.

Why is foil a good insulator?
Foil is considered to be a good insulator since it has the ability to reflect radiation. However, aluminium foil is commonly used as a conductor and not an insulator.
Is foil a good insulator?
yes
Is aluminum foil a conductor or insulator?
Insulator or conductor depending on the circumstances. Aluminum foil conducts heat, but it cuts off air flow and reduces evaporation of fluids. Aluminum foil reflects and thus minimizes radiation transmission. With foods it is more useful as an insulator. It also acts as an insulator on windows. But, aluminum is definitely a good heat conductor.
Is tin foil good for building a parachute?
Possibly, but tin foil is rather fragile, and easily torn. A cotton or silk fabric would make a better, more resilient, parachute.
Is tin foil a good conductor of heat?
There are three different ways of transferring heat. These are by radiation, conduction and convection. The sun's rays heat the surface of the earth by radiation. If you were to wrap a ice cube in Aluminium foil and place it in hot sunlight it would take longer to melt because the sun's radiation would be reflected. However if placed an ice cube wrapped in foil on a hot plate, it would melt just as quickly as if there was no foil. This is because in this case Conduction is the main way heat is passed to the cube and aluminum is a good conductor.
Why is tinfoil a good insulator?
It actually isn't a good insulator. Tin foil and aluminum are good conductors, not insulators.
Why is tin foil not a good thermal insulator?
because it conducts heat very well.
What insulator do you think wraps the best from tin foil brown paper and bubble wrap?
tin foil
Is tin fiol a good insulator or a good thermal conductor?
tin foil is bolth, because it is a metal so electricity goes through it and it holds heat well
Why is foil a good insulator?
Foil is considered to be a good insulator since it has the ability to reflect radiation. However, aluminium foil is commonly used as a conductor and not an insulator.
Which thermal insulator would have the least effect tin foil or brown paper or bubble wrap?
Tin foil is not a thermal insulator and so is irrelevant to the question.Bubble wrap is a better insulator at low temperatures but as the temperature increases bubble wrap will simply melt and provide no insulation at all.
Is foil a good insulator?
yes
How can you prove tinfoil is a good insulator through research?
You can easily prove that tinfoil is a good insulator a few different ways through research! 1) Construct a tin foil hat and wear it outside on a nice day. 2) Wrap a wooden match up in a strip of tin foil. Be sure the match tip is exposed at each end, then light the match that's rolled in the tin foil with another match. 3) Find a thermos and fill it with hot water. Close the thermos. Wait 3 hours. The water is still hot because its made of tin foil!
Is wallpaper a better insulator of heat or is tin foil better?
Any metal is a terrible insulator of heat. Wallpaper would be much better.
Name a material that is a good insulator?
Foil
What would be an example of a good insulator?
Insulators are objects that prevent the transfer of heat, so some good insulators would be cotton balls, tin foil/aluminum foil, socks, rubber etc. Get what I mean ? :O Later days, dude or dudette whatever you are.....
Find out name of things which work as conductor and insulator?
One electrical conductor is gold. An insulator would be rubber as it is what keeps people from getting electrocuted on wires A thermal conductor can be any metal. A thermal insulator is tin foil.
