Offering stylish design, energy efficiency, sun protection (including room darkening fabrics) and privacy, our shades beautifully cover virtually any window. There are various options and choices for arch top windows; cell shade arches, pleated shades, wood or faux wood arches. The stationary arches use stationary clips on the bottom to keep the bottom rail in place and a couple of smaller clips around the top to hold the fanned cellular material in place so it doesn't sag into the room.
