The window is still a radiator. Or more accurately, will still radiate heat received from a warmer source toward a colder destination. Heat tends towards dispersal (currently predicted, eventually, to evenly spread in all directions), so it seems wrong to say that the window "attracts" heat. Rather, it just provides lower resistance to heat transfer than the typical wall.
