Homeowners looking for shades that are guaranteed to help insulate their windows should consider installing a set of cellular shades. Uniquely designed in an ‘energy efficient’ honeycomb pattern, these interior ‘cells’ trap air to provide sound control and insulate windows against hot and cold temperatures. Attached and housed at the top of the window in an aluminum headrail, the shades are typically controlled by a pulley cord system. Cellular shades appear as smooth panels of fabric when they are closed over the window, then gather up on the pulley cords to fold neatly as they are raised in a manner similar to that of an accordion.
