Effertz has been producing rolling shutters for over 100 years and fire rolling shutters for more than 80 years. At the beginning of the 1970s, Effertz was the first manufacturer to receive general building authority approval in Germany for a rolling fire shutter. There is probably no company in the world that has more experience in the construction of rolling fire shutter with thermal insulation properties, as prescribed in Germany, Austria and Switzerland, but also in many other countries.
The advantages of rolling shutters are, on the one hand, the relatively low space requirement above the opening, as they are rolled up to save space, and, on the other hand, the possibility of achieving very large sizes. Since the individual shutter profiles can be moved against each other within certain limits, no internal stresses arise in the rolling shutter and it can deform relatively freely. As a result, there are no breaks or cracks even with large temperature differences, so that fire protection is maintained and temperature and flames remain safely comparted. An entry in the Guinness Book of Records in 1980 with the then largest fire protection rolling shutter in the Schaubühne in Berlin (Germany) proved Effertz’s ability to manufacture and install large rolling shutters for safe fire protection. This record-breaking rolling shutter still works today, reliably ensuring fire protection in this theatre.
