When you think of roller shades, you may imagine simple white spring action shades used in cheap hotels. The roller shades of today bear little resemblance to those old-fashioned shades with their mechanically advanced open and closure systems and attractive appearance. Aside from their beauty, roller shades are energy efficient and offer everything from room darkening options to sheer fabrics that let you look outdoors while still providing privacy. Roller shades are a simple and economical alternative window covering. Roller Shades open and close using a simple spring mechanism or other options such as a beaded chain or motorized systems.
