Wall covering is a general term for a permanent covering of a wall or the work of installing it. It describes any finish material applied to a wall structure to create a finished surface. While the terms are often used interchangeably, wall covering typically refers to loose-laid materials. Common materials classified as wall coverings include wooden panels, fabric panels, vinyl wall coverings, SPC panels, decorative panels, WPC wall cladding, acoustic panels, and epoxy wall coatings. These coverings enhance the aesthetics, functionality, and acoustics of a space.
