The Light Filtering Sheer Roller Shade features a combination of sheer and solid fabrics in a single shade. Much like opening and closing the slats of a blind, Layered Shades control light by alternating the bands from open to close. For more light leave the vanes open and light will stream in through the beautiful sheer fabric. For extra privacy and light control close the vanes completely. You can also raise the shades completely into their cassette valance and have a full view to outside with no obstructions in the window. 2 beautiful colors High quality construction Can be mounted inside or outside the window frame. Window must be 2 1/4" deep for inside mount; 2 5/8" deep for flush inside mount.
