The wood at the bottom of a wall is typically called the "baseboard" or "skirting board" (in some regions). Baseboards are long, narrow boards that run along the bottom of interior walls, where the wall meets the floor. They serve both functional and aesthetic purposes:
Protection: Baseboards provide a protective barrier to the lower portion of the wall from damage, such as scuffs, dents, and moisture.
Covering Gaps: Baseboards are used to cover the joint where the wall and floor meet, hiding any uneven or unsightly gaps between the two surfaces.
Aesthetics: Baseboards can enhance the overall appearance of a room by adding a finished look to the junction of the wall and floor, and they also help to define the visual style of the space.
Baseboards come in various materials, including wood, MDF (Medium-Density Fiberboard), PVC, and other synthetic materials. They are available in different heights and profiles, allowing homeowners to choose a style that complements the interior design of their home. The baseboard is usually installed after the wall and flooring have been completed, and it can be painted or stained to match the room's color scheme.
