Description: The Sorrento Blackout collection in the Serenade Roman Shades line features a silky smooth Polyester material. The material is room-darkening, blocking most light while giving complete privacy. The collection offers a white backing for a neutral appearance to street-side. The clutch operated Omni-Rise lifting system is standard for this product. Comfortex Roman Shades are offered with traditional tear-drop style to add dimension and interest or the more modern flat panel style for a clean lines look. A motorized lift option is available. Shades wider than 54” may require excessive pull force to operate. Motorized lifting system is optional.
