How much heat does aluminum foil give off?
Shiny side reflectivity is about 88%. It definitely picks up some heat. But it also conducts heat well, so loses it to cooler ambient air rapidly. It stays close to ambient temperature. Most of the heat gain at your windows is radiant, so with aluminum foil on the inside, you have reduced your radiant heat gain by about 90% . That’s pretty good. In direct sun you’ve got maybe 70–100 watts/sq.ft hitting the window, depending on angle, so with foil on the inside, with glass transmittance losses, that’s reduced to a heat gain of about 7-10 watts/sq.ft. So for a 3′x5′ window, you’d have about 105-150 watts of heat coming in through the aluminum.
How does heat transfer to a mass?
Heat is transferred to a mass in three ways, conduction, convection and radiation. Out of these three ways, aluminum foil polished surface stops (in a high percentage) the radiation only and not the conduction or con vection. So even if a sandwich is wrapped in aluminum foil and put in a furnace it will be heated anyway. On the other hand if aluminum foil wrapped sandwich if left to the sun beams it will absorb much less energy, in form of heat, than is its left without wrapping.

Is aluminum foil reflective?
It is not wonderfully reflective. It’s just OK. Shiny side reflectivity is about 88%. It definitely picks up some heat. But it also conducts heat well, so loses it to cooler ambient air rapidly. It stays close to ambient temperature. Most of the heat gain at your windows is radiant, so with aluminum foil on the inside, you have reduced your radiant heat gain by about 90%. That’s pretty good. In direct sun you’ve got maybe 70–100 watts/sq.ft hitting the window, depending on angle, so with foil on the inside, with glass transmittance losses, that’s reduced to

it offers a small amount of shielding. Copper foil is better. The one from 3M shielding tape offers a good shielding suitable for various frequencies from 30Mhz up to 1Ghz
How thick is foil for microwave?
I used to use it a lot to improve microwave shielding. The skin depth for microwaves is about a micron, and about 30 MHz it is 10 microns, so aluminium foil is thick enough.
Why use foil tape for EMC?
In Radio frequency EMC tests under Equipment/Devices, when the behaviour of the device is not quite well because the equipment is not quite good designed regarding EMC issues , the Aluminium foil tape can be used to obtain improved behaviour. I mean, if some part of a cable is not properly shielded, this can be a weak point of the installation. Therefore, in order to check if the behaviour is improved during the test campaign, the Aluminiun tape foil is used to check it. This measure can improve the results of the tests.

Which is better, copper foil or aluminum foil?
Copper foil could have higher shielding effectiveness due to its higher conductivity but for shielding magnetic fields at lower frequencies (lightning), aluminium foil may be a better choice due to its higher relative permeability (around 2.2).
Does foil shielding protect against radiation?
Not really. The use of a foil for shielding will help reduce the effects of externally generated radiation, but will not protect against radiation from internal components. There are other more effective solutions offered by some companies (as those suggered by Aparna in the first answer).
