I am often asked about options for sliding patio doors. The least expensive option and one that everyone is pretty familiar with is Vertical Blinds. They are very functional and we still sell a lot of them. It used to be one of the only options for people but Hunter Douglas, in particular, has really ramped up the number of choices.
You can do woven woods, honeycombs, and even roller shade fabrics that track horizontally. Our favorite, however, is the Luminette. It incorporates the simplicity of the vertical blinds with the elegance of sheer draperies.
We recently installed these Luminettes in Nashville, TN and the homeowner could not be more thrilled. The goal was to add the beautiful look and be able to control light and privacy to their back yard. As you can see, mission accomplished on all fronts!
