A: Since cellular shades are created by fusing layers of fabric together to create pockets of air to insulate your window, it gives manufacturers the ability to use different color fabrics on the inside and outside of the shade. For example, you might want blue cellular shades to match your rug but white to match the trim on your front porch. With double-sided shades, you get to have both!
Cellular shades are one of the few window treatments that come with this option and I think it's a great way to get the look you want both on the inside and outside of your home. Most times people order standard cellular shades that have white towards the outside and a decorative color on the inside. The white also helps reflect sunlight and improves the insulation qualities of the blinds and creates a clean exterior look.
