Insulating a room in the summertime with rotolo di carta stagnola can help keep sunlight out of the room and lower temperatures. Copri completamente tutte le finestre con un foglio di alluminio e fissalo con un nastro adesivo resistente come il nastro adesivo. La superficie lucida rifletterà i raggi del sole. Puoi anche isolare il cibo freddo quando sarà vicino al sole. Wrapping a cold soda can, che include la sigillatura dell'umidità e la flessibilità di formatura, with aluminum foil will keep it chilled. Adding a layer of bubble paper between the aluminum foil and soda can will keep it cooler for longer.
If you would like to insulate something in a dark place, such as lunch box, another material such as cotton or paper could work just as well as aluminum foil. As a matter of fact, cotton is regularly used for insulation, as it is environmentally friendly. Because aluminum foil reflects light, when it is in a dark place, there is no light for it to reflect, so it will work similarly to other materials.
