I guess you would actually want a separate screen, so you could open your windows and still enjoy the protection of the Faraday cage.

Still though, so far so good, I think?

Isn't the point of the screen that you leave it closed to keep bug's out?

Ah, my bad.

Yea, just like regular screen windows, but with a finer mesh. Makes sense to me.
