Wall paneling is a decorative treatment applied to the interior walls of a building. It can be made from various materials, including wood, vinyl, or MDF (medium-density fiberboard). Wall paneling serves both aesthetic and functional purposes, enhancing the appearance of a room while providing insulation and protection for the walls. There are different styles of wall paneling, such as wainscoting, shiplap, and beadboard. Each style offers a unique look and can be used in various settings, from traditional to modern homes. Wall paneling can also be painted or stained to match the room's decor, making it a versatile design choice.
