Cellular shades are Westbeach’s specialty. Looking to keep your home cozy in the winter; keep it cool in the summer? Cellular shades are the best insulator against outside temperatures. They are also the best product for room darkening and light control. These shades come in both room darkening and light filtering fabrics. One other bonus add-on feature is the top down bottom up (TDBU) function. This function has regular control but, you can also drop the shade from the top to let even more natural light in and also to expose your beautiful view.
