Are you wanting the curtians for asthetics or absorbtion? How much surface area are you considering covering/which walls? Just thinking cause too much can be overkill & deaden the room.
Wanting it mainly for looks, to block out sunlight out of a double window on my right side, and to absorb stray light from the projector especially since it is a black room with white windows and illuminating the window is pretty annoying. Then I want to duplicate it on my left side as to be symmetrical. I assumed having it be as sound absorbing as possible is a good thing but I don't have any provable need for it.Are you wanting the curtians for asthetics or absorbtion?
