Cellular shades have a honeycomb design that makes them energy efficient due to cell-shaped pockets that trap air and sound. They come in a wide variety of colors and are very versatile: You can choose a cell thickness that best meets the needs of your home; the thicker the cells, the greater the light filtration. Due to their flexibility, cellular shades are available in a variety of shapes and sizes.
There are even cellular shades available to fit windows with arches.
