Europe’s largest timber-built hybrid hotel

Sustainable protection against noise and vibration with a lightweight construction.

The new “Vienna House Easy by Wyndham” is already setting new standards even before it opens its doors. Currently under construction at Schwechat Airport in Vienna, it will be Europe’s largest timber-built hybrid hotel when complete. With its 510 rooms, it will not only be the biggest hotel at the airport but also the fourth largest hotel in Austria as a whole.

In keeping with the developer’s aims, the focus lay on using ecological building materials. In addition to the hybrid timber design, the sustainable construction also makes use of carbon-free heating and cooling.The hotel has three wings coming off a long central building, with the staircases being constructed from reinforced concrete to act as a bracing core. Around 10,900 m2 of cross-laminated timber walls create space for the five floors, which are supported by the ground floor constructed from reinforced concrete.

Thanks to a high degree of prefabrication and well-planned logistics – supported by our partner Haberkorn – the entire timber shell was constructed by Graf-Holztechnik in Schwechat in just three and a half months.

Decisive factors in choosing Sylodyn® were not only its low settling but also its excellent long-term performance. This ensures that its pronounced spring properties provide effective protection against airborne and impact noise for decades.

The benefits

The challenge

Effective sound control poses a particular challenge. Compared to solid construction methods, using wood – a lightweight material – means that vibrations are conducted to a much greater extent, both from airborne and impact noise. Effective isolation of vibrations becomes extremely important here, with careful planning, expertise in architectural acoustics and innovative detailed solutions required. Of particular importance is the use of vibration engineering techniques to decouple flanking sound at the component joints.

Sylodyn®

The solution

In total, around 2.000 Sylodyn® strip elements (each one 12.5 mm thick) were laid, which equates to a total area of around 300 m2. As part of a customised design, different types of the high-tech elastomer were selected based on the compressive load and vibration frequency.

We received excellent support from the experts at Getzner and Haberkorn, who ensured that the Sylodyn was customised exactly to our requirements, perfectly synchronised with the construction progress and delivered on time – an impressive solution for this large cross-laminated timber project.

Flanking sound decoupling

The application

Flanking sound decoupling with Sylodyn® from Getzner is used to reduce sound transmission via flanking components
(e.g. walls, ceilings, supports) in buildings. Direct contact between the components is interrupted by elastic bearings produced from Sylodyn, a high-performance polyurethane elastomer.
