The STANDARD 14 Jacob is a roof tile slightly bent produced on the factory site of Commenailles in the Jura, posed with crossed joints, or right joints when the slope is sufficient. The traditional format and forms
of this roof tile, its rustic colors, make it possible to carry out roofings
in the respect of the traditions. Its implementation since more demisiècle in areas of mountain to the rigorous climate, is worth an exceptional reputation to him which extends on Burgundy, the Franche-Comté and the Alps.
