The basic form of this tile dates back to the 19th century and it has the classic form of the Rheinland tile. Once installed, this tile provides a subdued rooftop look that fits in with many different styles of architecture.
Compared to the R 15, the larger format of the R 13 S reduces installation costs. In addition, it can be used as a sliding tile variable in the deck lengths 31.0 cm to 36.5 cm on existing load-bearing roof constructions in the covering.
The flat curvature of the R 15 has been characteristic of German roof landscapes for more than a hundred years. It is often used on rectilinear and flat roof frames.
