Will Aluminum Foil Block Radiation
Metals in general block electromagnetic radiation (which is whata Wi-Fi signal is). Aluminium foil is a metal, so.Exactly howthis happens is a bit more complicated than can reasonably beexplained here, but it basically has to do with the fact thatmetals are conductive. They 'absorb' the electromagnetic signal andturn it into electrical currents within the metal.You don't even need to use solid metal, you can accomplish thesame thing with a wire cage as long as the spacing between thewires is small compared to the wavelength of the radiation (forWi-Fi at 2.4 GHz, this is about 5 inches). This is called a'Faraday cage.' The basic concept is used in a lot of electronicsdevices to shield out interference (or keep the device frominterfering with anything else), though it's more common for themto use a piece of thin sheet metal with maybe a few holes in it forventilation than to go to the trouble of constructing a wiremesh.
