Spacious wrap-around balconies and a prestigious staircase in the atrium are some of the many distinguishing architectural features of six apartment buildings that have sprung up in the new car-free district in Berlin-Pankow. The solution for meeting enhanced requirements relating to sound insulation was met with Tronsole from Schöck. An acoustical decoupling of the stair flights and landings from the stairwell walls and ceilings is required to avoid the transmission of sound to neighboring spaces.
Installation
Tronsole was installed directly on-site before the assembly of the staircases. The half-spiral stair flights of this project were produced as precast elements. Because this property has a free-hanging staircase, Tronsole was installed exclusively at the start of the stair flight on the ground floor and at the support points of the walkways. Thus, the staircase is decoupled acoustically from the building.
Sound Insulation
The essential component of Schöck Tronsole is the elastomer bearing Elodur, which can achieve a 10 dB higher impact sound insulation compared to regular staircase supports. The acoustic characteristic values of the Tronsole are tested according to German regulations DIN 7396. Because of the Elodur elastomer bearing, an impact sound level difference of 27 dB to 33 dB is achieved.
