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? (linux.community)

I need an air current in this room, even when the sun shines directly into it.

I was thinking covering the hopper window with either paper or reflective foil and leaving it a bit open, but I don’t know if this is a stupid idea.

A closed window means an unlivable room.

I've just done an experiment with horticultural sheeting on all my (huge) bedroom windows and it did not work. Any type of reflective material would need to go on the outside of the window to work.

If you are able to, give it a try and see what happens.
