The highlights included single and double-leaf multifunctional doors that met the requirements for fire protection (T30), smoke protection and sound insulation with a value of Rw, P = 47 dB.

Another central element of the project was a glazed dividing wall in a T90 version, comprising two single-leaf doors and five fixed glazed central panels. Particularly challenging were highly sound-insulated doors for the conference rooms, which were seamlessly integrated into the wall development, providing a perfect combination of functionality and aesthetics.

A particular highlight of the project was an airlock element with the impressive dimensions of 2,500 x 4,200 mm, which was measured on location with an outstanding sound insulation value of 59 dB. This comprehensive door and wall system junctioned technical excellence with first-class comfort and blended harmoniously into the sophisticated overall concept.
