The Double-S concrete tile originates in Northern Germany, in the windy areas close to the Baltic and North Sea coasts. Its gentle, flowing lines deflect even strong winds over the surface, and offer excellent protection against driving rain. Its singular shape creates an interplay of light and shade, giving roofs added depth and texture. Doppel-S tiles are also sold outside of Germany under different names in Poland, the Baltic States, Scandinavia and the UK, and are available in a range of different colours to blend harmoniously into any setting.
