Ang aluminyo foil ay isang mahusay na insulator ng init dahil ito ay isang mahinang konduktor ng init. Ang init ay maaari lamang ilipat sa pamamagitan ng isang materyal sa pamamagitan ng pagpapadaloy, kombeksyon, o radiation. Sa kaso ng aluminum foil, Ang paglipat ng init ay nangyayari pangunahin sa pamamagitan ng radiation, na kung saan ay ang paglabas ng electromagnetic waves mula sa ibabaw ng isang bagay.
Ang aluminyo foil ay isang makintab, reflective material that reflects radiant heat back towards its source. This means that if you wrap an object in aluminum foil, it will reflect the heat from the object back towards the object, rather than allowing it to escape into the surrounding environment. This can help to keep the object warm or cool, depending on its temperature and the surrounding conditions.
Bukod pa rito, aluminum foil is a thin material, which means that it does not have much mass to absorb and transfer heat. This makes it less effective as a conductor of heat, and therefore a better insulator.
Overall, aluminum foil’s combination of reflectivity and low thermal mass make it an effective heat insulator.
