Tiles are becoming more and more popular for roofing. Small RHEINZINK-tiles (square and diamond-shaped) provide secure and aesthetically pleasing solutions, even for geometrically complicated building designs. Dormer, chimney head and roof edge cladding counts as part of conventional tile utilization. RHEINZINK-Flat-Lock tiles are most effective for large roof areas and curtain walls. These represent a further development of the diamond-shaped and square tiles; they are impressive, not only because of their aesthetic appeal, but because of the design benefits. Using different sizes of tiles opens up a multitude of façade design possibilities. The bright rolled version provides more design options, because the natural weathering of the shiny material will vary from tile to tile, which can be quite striking.
