Why does household aluminium foil have one dull side and one shiny side? SO THAT the shiny side can reflect the heat on to the item to be cooked, using a long-established scientific principle that shiny surfaces reflect heat and light.
When using aluminum foil to wrap food, the general recommendation is to place the glossy side in contact with the food. The glossy side is slightly more reflective and can help to retain heat better. However, the difference is minimal, and either side can be used effectively for cooking or storing food.
The shiny side of aluminum foil reflects more light than the dull side. This is because the shiny side is a smoother surface than the dull side, making reflection occur in a more regular manner. Very smooth surfaces appear shiny because light reflects in a regular, predictable way.
Yes, foil on the window will reflect the heat of the sun away from the house and save energy on air conditioning. Taping aluminum foil shiny side out, to the outside of the window glass would probably reflect more heat away, keeping the inside cooler, since convective cooling would cool the foil somewhat.

If you install double faced insulation it doesn't really matter which side is out. Neither side does the same job. Therefore, it is recommended to use insulation with foil on both sides.
Shiny side up. Your vehicle hasn't flipped over after a rollover or accident. “Keep the shiny side up” means to have a safe trip.
There are several reasons for foiling up the door knobs. Some of them are to avoid the paint stains on them while painting the door or the house. Yet another reason is to make sure that it provides insulation against heat and remains cold when it is being opened.
Conclusion. While aluminium foil may seem like an easy and inexpensive solution for creating a dark room, it is not a good option for blackout window coverings. Not only is it not a permanent solution, but it can also be a fire hazard and can look unattractive.
According to the U.S. Department of Agriculture, aluminum foil's two-sided finish is the result of its production process. When the material passes through rollers, two layers of foil are pressed at the same time, which reduces the risk of breakage. As a result, one side is shiny and the other is matte.
Either side of the foil can be used to place food on, unless you are using Bacofoil® The Non-Stick Kitchen Foil, then the food should be placed on the non shiny side side, as this is the side that is coated with a food safe silicon to stop food from sticking.
Suppose you want to keep your food warm and you've got nothing else. In that case, the simplest way is to wrap your food directly in aluminum foil. Or, you can put the food in a container and then wrap the container in thick aluminum foil. Note: You can cover the foiled food container in a towel for better results.
Tin foil is stiffer than aluminum foil. It tends to give a slight tin taste to food wrapped in it, which is a major reason it has largely been replaced by aluminum and other materials for wrapping food.
Aluminium foil is too thin to have any thermal inertia and will not have capacity to dissipate heat at the rate at which it is generated. Heat sink is usually given fins or shapes to increase its area beyond what can be given by a plain surface.
Aluminum foil can serve as a barrier to prevent external light sources from penetrating the glass. This is particularly useful in the early morning or evening when light can interfere with sleep. In addition, the reflective properties of aluminum foil also contribute to improving privacy.
While these methods seem to pose huge security risks to your vehicle, there is actually quite a simple solution to protect your car: wrap your keys in tin foil. Wrapping your keys in this every-day household item will act as a barrier and ensure that the signal is not transmitted in a relay attack.
It is widely claimed that adding aluminum foil to a toilet tank helps to achieve a clean and shiny toilet, but critics challenge these claims due to a lack of scientific evidence.

This is a way of expressing respect towards the other motorcyclist. It's our way of saying, “Hello! Keep the rubber side down, keep both wheels on the ground”. It signifies that the rider is wishing the fellow rider to stay safe and ride safe.
