Am I going to reduce a room’s temperature covering a huge hopper window with either paper or reflective aluminum foil, but leaving the window a bit open when the sun shines directly into the window?

Open all the windows during night time when its cool, close windows and shutters during daytime. If you dont have shutters, put foil on the outside of the window, not inside. Also use a fan for air flow.
