Sticking aluminium foil to the inside of the window will block *all*
light and reflect heat. There would be no problem with heat buildup
in the glass.

If this is really what you want to do the cheapest option (IMHO)
would be to simply paint the windows white, perhaps use greenhouse
paint that can be washed off (though this will not produce the same
blackout as aluminium foil). If you want something more reversible
you could use blinds.

It's possible you are thinking of UV blocking window film in which
case please ignore the above.
