Nelskamp has been producing concrete roof tiles since 1953. They are made using quartz sand, cement, water and colour pigments. The first model – the "Finkenberg Tile" – is still in popular use in Germany. Four further concrete roof tile models are also available for individual roof architecture: S-Tile, Planum, Crown Tile and Sigma Tile. Clay roof tiles are a favourite construction material steeped in tradition. The manufacturing process has remained almost unchanged since 1926: the pressed clay tile obtains its final hardness and structure at 1,000 degrees Celsius. Correct installation of the tiles and regular maintenance will ensure that your roof brings you joy for many years to come.
