SYLODYN

The material for the most stringent requirements

Sylodyn® is used as a vibration protection solution on local and inter-city railway lines, but also for isolating impact noise in floors and on stairs, as a bearing for buildings or machines, or for isolating noise between walls, floors and ceilings. Sylodyn® is a closed-cell elastomer that does not absorb water. In comparison to Sylomer®, the material offers improved dynamic properties. Five different types of Sylodyn® as well as three different types of Sylodyn® HRB HS are available from stock. Its properties can however be tailored in order to meet specific requirements.

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.
