Product Characteristics

Elastic support and vibration isolation for buildings and rail infrastructure is an important factor in quietly improving our enviroment. All Novodamp solutions are suitable for natural frequencies ≥ 8 Hz and up to a load-bearing capacity of 12 N/mm² (1740 PSI). Depending on shape factor, thickness and elasticity, the dynamic properties can be adapted to meet project demands.

Product Applications

Protection against noise and vibration for rail tracks
Vibration protection for buildings & building extensions

When designing with Novodamp, the application and the associated load cases must always be considered, particularly the load combinations expected for each application. In buildings, for example, the load is normally characterized by high permanent static loads and low dynamic amplitudes. In the case of rail tracks, the load is characterized by low static load with a high dynamic component.
