Valances. This particular kitchen has two very decorative architectural valances — one over the desk and one over the range. Valances can help cover necessary but unattractive electrical items that might be visible when your viewing height changes — like at the island or adjacent table in this photo. The valance on the range covers the exhaust fan, and the valance over the desk area covers the undercabinet lighting. Valances come in all shapes, sizes and styles to fit any design. The majority are ordered in predetermined lengths and then cut down onsite to fit.
