DUETTE® The Pioneer of Design and Efficiency. Duette® Honeycomb Shades are the original cellular shades, specifically engineered to provide beauty and energy efficiency at the window in both cold and warm climates. Their honeycomb construction traps air in distinct pockets, which creates insulation that can help lower your energy consumption and energy bills. Duette shades are available in an expansive range of pleat sizes, fabrics, colors, opacities and textures. Innovative operating system design options such as Top-Down/Bottom-Up and Duette Duolite® make these shades a top choice for any window, skylight or even specialty window shapes like arches, sidelights and circles.
