Window treatments are the least expensive way to transform a room. They can create an illusion. For instance, by installing draperies above the window frame the window will appear taller and the cieling higher. To make a small window look larger the window should be installed outside the frame of the window, thus exposing the entire window. Dressing a window gives a room a warm appeal, absorbs sounds, echos, provides privacy, acts as insulation, and eliminates reflections caused by artificial and natural light.
