| Regupol BA in the Cologne RTL studios  Cologne, the business and cultural metropolis of the Rhine, and Germany's fourth largest city with a population of around 1 million, boasts almost 2,000 years of history. Cologne cathedral, the construction of which began in 1248, is the emblem of the city, the third largest Gothic church in northern Europe, and was the highest building in the world from 1880 to 1884. The buildings from the recent past also characterize the cityscape, as do the Rhine Halls in the Cologne-Deutz area of the city. The 80 metre high fair trade tower and the halls, both with suspended brick facades, were preserved after the withdrawal of Kölnmesse in 2005 and when RTL, Europe's largest commercial television broadcaster, moved in, due to their status as protected historic monuments. After the entire building complex was cleared, by 2010, the site housed the largest office building in Germany, with a gross floor area of 160,000 square metres. Besides a highly modern administration complex, the new area also houses the media group's new broadcasting centre. All technological equipment has been installed on the ground and first floor, along with the studios, which extend over several floors in the western part of the building. Due to the building structure and use, special attention was given during the planning stage to ensure the sound insulation requirements for the production area (studios, media recording, direction, editorial offices and service) of around 17.000 m². This soundproofing was mainly focused on the two studios, with dimensions of 250 m² or 440 m², as well as on the commentators' booths. For the ceiling and wall area, decoupling lining, absorbers, etc. ensure the necessary sound insulation and optimum acoustics. A technological vibration solution to minimize structure-borne or air-borne sound was devised for the floor design by BSW, in conjunction with the specialist planners. The tried and tested screed insulation, Regupol BA, was used – a PU-bound rubber-fibre mat with German national technical approval and European technical approval. To optimally reduce the impact sound level, triple-layered installation strips of 17mm thick permanently elastic insulating mats were designed, combined with mineral-fibre mats. Parallel to the wall, three strips of Regupol BA were laid one over the other; surrounding and stabilising the floor insulation framestyle. write your comments about the article :: © 2012 Construction News :: home page |
