Defining Trim and Molding

Trim refers to the decorative elements used to cover the edges of walls, doors, and windows. It is typically made of wood, MDF (medium-density fiberboard), or PVC, and is used to create a finished look at the edges of a room. Trim can be used to cover unsightly gaps between walls and floors, or to create a decorative border around doors and windows.

Molding, on the other hand, refers to the decorative elements used to add visual interest and depth to a room. It is often used to create a sense of layers and texture, and can be used to create a focal point in a room. Molding can be made from a variety of materials, including wood, plaster, and MDF.
