tiles
A facade composed of many hard units which are individually mounted to a back surface.
Because of the autonomous nature of tile units as opposed to masonry, they offer a greater range of decorative possibilities, and are often used for ornamental or aesthetic reasons.
Many types of stone, especially limestone, marble, travertine, and granite, are often applied as tiles rather than as masonry units. In this case the stone tiles may be arranged in straight rows like masonry, or can also be arranged in any other pattern.
