Solid timber apartment building by Meickl

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.

The challenges

Airborne and impact noise insulation in a multi-storey timber construction
Sound insulation without decoupled wall linings improves the quality of the indoor environment
Measurements carried out on the completed building confirm that all sound insulation requirements have been met

The Getzner solution

Getzner offers a comprehensive vibration isolation solution which minimises sound transmission in a multi-storey solid timber construction.

In addition to designing an elastically suspended ceiling, the flanking elements and fasteners were also elastically decoupled. A high-quality ceiling construction significantly reduces direct sound transmission. Sound transmission via the flanking elements then becomes the key factor. Getzner mounted all the joints between the walls and ceilings using the high-tech material Sylodyn® in order to decouple sound transmission by this route.

To prevent sound bridges, the specially developed ABAI 105 elastic angle brackets from Simpson Strong Tie® were used in conjunction with decoupled screws. This elastic fastening system optimally separates the building components – without affecting the load-bearing capacity of the structure or increasing sound transmission.
