  Aluminum foil, also called tin foil, makes an excellent insulator, and in some situations, it works better than materials like cotton or paper. Aluminum foil is not best for every situation, though, so using it correctly is an important part of saving energy.
  
  Insulating a room in the summertime with aluminum foil can help keep sunlight out of the room and lower temperatures. Completely cover all windows with aluminum foil and secure it with a heavy-duty tape such as duct tape. The shiny surface will reflect the sunlight's rays. You can also insulate cold food when it will be near the sun. Wrapping a cold soda can, for instance, with aluminum foil will keep it chilled. Adding a layer of bubble wrap between the aluminum foil and soda can will keep it cooler for longer

  Aluminum foil is not an insulator. Aluminum foil has good conductivity and ductility. However, after oxidation of aluminum foil, the surface will form a dense oxide film, this film has a very good non-conductive properties.The thickness can be increased through the process of anodizing.Anodized Aluminum Sheet

  The side that the aluminum foil is placed on affects how it insulates. For example, placing aluminum foil on the outside of a box keeps the inside cooler by reflecting heat away from the box. However, placing aluminum foil on the inside of a box helps keep heat from escaping. According to the Cold Climate Housing Research Center, foil is often used for reflective insulation in attics, but is most effective in warm climates.
  Insulation is not used to keep cold air from entering an area. Instead, it is used to slow down or prevent the flow of heat from one area to another. Heat is only able to flow in a single direction: from something warm to something cool. Insulation serves as a way to slow down this process. Even insulation in a refrigerator is not used to keep cold air inside but to prevent heat from getting inside the refrigerator.
