SYLODYN

Sylodyn® is the next stage in the evolution of the proven Sylomer® material and boasts a higher degree of dynamic stiffness paired with significantly reduced internal damping. The material is a great fit for any application requiring precise vibration isolation in combination with a high load, such as on high-speed railway lines or with highly sensitive technical equipment. In addition to its high dynamic load capacity, the closed cellular structure of Sylodyn® means it does not absorb any water – a critical factor when it comes to vibration-isolated bedding of building foundations. The Sylodyn® HRB (high resilient bearing) series was developed for extreme loads in confined spaces, such as crane installations, steel structures and heavy machinery. Sylodyn® is also particularly effective when used to insulate impact noise and for acoustic decoupling between walls, ceilings and floors.

Case Study

Solid timber apartment building by Meickl, St. Johann

The timber construction and carpentry company Raimund Meickl constructed a modern apartment building with solid wooden panels to passive building standards. A top-quality indoor environment requires effective protection from airborne and impact noise. Sound control within the building is just as essential as sound insulation against noise from outside. The construction company contacted Getzner, a specialist in vibration protection, for help in minimising sound transmission.

Elasticity for the slab track in the Gotthard Base Tunnel

At 57 kilometres in length, the Gotthard Base Tunnel is the longest rail tunnel in the world. It links the Swiss communities of Erstfeld and Bodio. The tunnel forms part of the New Railway Link through the Alps (NRLA), which is at present the largest construction project in Switzerland.
