I was thinking of placement of the screen to reduce glare from the windows and have a crazy idea. Our kitchen, dining room and living room are all one room. There is a window and sliding door in the kitchen/dining room. I was thinking I can hang a screen at the end of the living room where it meets the kitchen/dining area so that the back of the screen is facing the windows. It would'nt hang on a wall as there is'nt one at that location, so i'd get one that I could manually roll up and is mounted to the ceiling. How does that sound? Can the light penetrate the screen from behind?
