Trim molding is a decorative element used in construction and interior design to enhance the appearance of walls, ceilings, and floors. It comes in various styles and materials, such as wood, plastic, or composite, and is often installed around doors, windows, and baseboards. Trim molding helps to create a finished look and can also cover gaps between different surfaces. In addition to its aesthetic appeal, trim molding can serve practical purposes, such as protecting edges from damage and hiding imperfections. It is available in different profiles, including crown molding, baseboards, and chair rails, allowing homeowners and builders to choose the best fit for their design needs.
