TRIPPLE SHADE

Triple Shades close the gap between Venetian Blinds and Curtains in a truly unique design that features fabric slats suspended between two sheer fabric facings for complete light control and privacy. ... It provides the functionality of two blinds in one shading.
Cellular shades are often the most effective at blocking light. These shades are constructed with either a single or double layer of hollow cells, which not only block light, but also improve insulation and muffle noise.
