Abstract

A tile-shaped composite element is described in which a ceramic tile serving as the visible tile is glued to a further ceramic tile serving as the base tile. In order to add considerable strength to the two single tiles, thereby substantially improving the sturdiness of the composite element, it is proposed that each tile be provided on the back with a nesting structure and glued together with this nesting structure back-to-back. Since the wall thickness of such a composite element may correspond to the usual wall thickness of shingles or conventional ceramic tiles, extremely thin tiles may be used as the base tile and the visible tile placed thereupon. Because there is a nesting structure on the backside, the tiles may be connected and glued together in such a way that the nesting structures, which generally involve continuous straight grooves and ridges, positively engage to lock into each other, thereby considerably strengthening the firm cohesion of the tiles and, thus of the composite element.
