Vertical blind textures, colors and patterns provide the affordable solution for patio doors and large windows. The fabric selection includes crossovers to the Premier Roller Shade offering. Many fabrics can be inserted into the clear channel panel to provide more stability and energy efficiency to the louvers. And S-shaped louvers offer the choice of left-facing or right-facing orientation to direct the sunlight and maximize privacy. All Vertical Blinds come with a dust cover valance.
