Your contractor for airtightness is Ingenieurbüro n50!
For over 25 years, we at Ingenieurbüro n50 have been specialists in the field of airtightness of rooms, buildings and industrial systems. During this time, we have completed a plethora of exciting tasks: starting with special measurements on façade elements of the European Central Bank to checking the server rooms of Deutsche Bank and leak tests of high-security laboratories of the Robert Koch Institute.
Further project highlights include: Advice on the construction of a high-bay warehouse in Istanbul, advice and leakage measurements during construction for a paper roll warehouse in Germany, advice and accompanying measurements during the construction of a hall for the storage of soil contaminated with explosives and numerous metrological inspections of storage and deep-freeze warehouses with oxygen reduction systems. In the Nant de Drance project, a pumped storage power plant in Switzerland, we were able to confirm the effectiveness of the gas extinguishing systems with our gas concentration measurements as part of a test flooding.
Whether airport buildings or transformer houses: No building is too big or too small for us, no measurement task too complicated. This is why customers from 17 countries in Europe and the Arab world have successfully entrusted their projects to n50's expertise.
