Particularly in the sector of single-family homes, but also at public buildings the concrete roofing tile is an extremely popular roofing material.
Every year our company carries out a large number of roofs with it.
Its uncomplicated laying in comparison to other roofing materials and the savings of wage costs connected with it, as well as the affordable purchase costs of the material make the concrete roofing tile a genuine alternative especially in the sector of single-family homes.
Below we mention some references of the last years to you
History of the concrete roofing tile
In 1844 Adolph Kroher, owner of a quarry in Staudach in Chiemgau succeeded in producing "concrete roofing tiles". With it it was for the first time feasible to use concrete as a material for a roofing material that could be industrially and economically produced and at the same time was dimensionally stable and not combustible. Even today there are intact roofs that were covered more than 140 years ago with Kroher's tiles.
Even in ancient Rome the material concrete was already known for the production of building components out of poured concrete (opus caementitium). Koher invented a process making it feasible to produce roofing tiles out of concrete. In these days these roofing tiles spread primarily because of their stability against frost and high breaking strength over the entire Alpine region with its extreme climatic conditions. Whilst to begin with roofing tiles were produced on manual chipping tables, the automated production made its entrance into England around the turn of the 19th to the 20th century. There the concrete roofing tiles developed into the most frequently used roof building material. In the country of their invention - Germany - however they led a marginal existence for a long time.
Only the rebuilding after the war and the unbroken will of an entrepreneur convinced by the idea of the concrete roofing tile achieved the breakthrough of the product. With the for the first time mechanically produced roofing tile "Köpperner Platte" and finally with the "Frankfurter Pfanne" rolling off the assembly line as from 1954 Rudolf H. Braas set permanent benchmarks for the building industry.
Raw materials obtained from nature - mostly out of native regions - are used for the production of Braas pantiles. The main raw materials are washed sand of high quality, limestone burnt into cement, iron oxide pigments and water. Braas roofing tiles are produced exclusively out of constantly controlled raw materials according to strict specifications and thus guarantee top quality.
The tested raw materials are mixed and measured out in modern, process-controlled preparation plants. Forming of the surface contour is carried out under strong pressure. The packed and profiled material leaves the machine as an endless string that is separated with special knives into the individual pantiles.
After the first shaping of the surface follows the hardening process. For this purpose the fresh roofing tiles are placed into spacious hardening chambers. Here they stay for eight to twelve hours at approximately 60° Celsius.
After a second shaping of the surface the separation of the roofing tiles from the bolster plates is carried out. A strict quality control follows. The roofing tiles achieve their final compactness without any additional energy expenditure after 28 days of storage in the open air. Now they are ready for roofing.
