Roller Shades are custom built to offer smooth operation along with the feature of totally blocking out light coming through the night shade fabric. Offered in a dual (Day/Night) and a single (Night only) configuration. The dual's mesh sheer fabric allows a small amount of light to penetrate while offering a degree of privacy while the night portion blocks as much light as you want depending on the position of the shade. Easy to install and easy to maintain roller shades present a clean smooth appearance to your decor.
