Establishing the amount and type of light in your home is essential to the creation of a pleasing atmosphere.  Duette honeycomb shades offer four gradations of opacity ( the degree to which light penetrates fabric ), which allows you to choose the amount of incoming light and level of privacy.  Choices range from sheer which reveals considerable detail to opaque which blocks up to 99% of incoming light.  You may also choose the Duoliet option which is two fabrics on one shade, providing both natural light and privacy.
