Ornamental moldings are decorative elements used in architecture and interior design to enhance the appearance of walls, ceilings, and furniture. They come in various styles and materials, such as wood, plaster, or polyurethane, and can be found in homes, public buildings, and historical structures. Common types include cornices, baseboards, and chair rails, each serving both aesthetic and functional purposes. These moldings can add character and elegance to a space, often reflecting the design trends of specific periods, such as Victorian or Art Deco. They can also help to define different areas within a room, creating visual interest and depth.
