Aarsun’s Unique Design Corner Molding is used to decorate a ceiling in many creative ways adding an architectural focal point to any room with style and beauty. For example, the cornice over a door or window, around the top edge of a pedestal, or along the top of an interior wall. A simple cornice may be formed just with a crown, as in crown moulding atop an interior wall or above kitchen cabinets or a bookcase. It serves an aesthetic as well as a functional purpose in both residential and commercial buildings. It is typically a moulding that comes in uniform pieces that can be laid side by side on the joints of walls and ceilings.
