Alpstadt Lifestyle Hotel exemplifies the latest modular construction methods in wood

The newly opened Alpstadt Lifestyle Hotel in Bludenz sits on a hillside providing breathtaking views of the valley and surrounding mountains. The construction method used for the split-level, 3,000 square metre building is one of its stand-out special features: the seven-storey hotel was designed using sustainable construction methods in wood. The modular prefabrication process took place in parallel with the excavation and structural works, allowing construction of the hotel rooms to proceed expeditiously – taking just nine months from start to finish.

The aim of the hotel owner was to create a retreat for business customers, the active holidaymaker and those seeking rest and relaxation. The same fundamental requirement applied for all guests, whoever they might be: the need for peace and quiet. As such, effective sound control was a key aspect in the design of the project.

The challenge

Wood is much lighter than other building materials and it therefore takes very little energy to generate vibrations. The wooden modules are particularly susceptible to vibration and the propagation of unwanted noise. Timber was chosen as a building material due to its ecological properties and the warm interior ambience it creates, and is key to the look and feel of the rooms throughout the hotel.

The Getzner solution

To prevent sound transmission between the different floors, the individual modules were bedded on Sylodyn® from Getzner.

Getzner not only provides elastic bearing for modular construction projects, but also for element and hybrid construction methods. Each timber construction is considered as a whole, and the flanking transmission of structure-borne noise is avoided to improve the acoustics. Alongside the highly effective Sylodyn® strips for the bearing of modules, achieving effective soundproofing is also a matter of choosing the right fasteners between the wall and ceiling – such as GEPI angle brackets or Sylodyn® washers. This combination enables the very best sound control results in timber construction projects.

The benefits

Highly effective sound control to create high quality living and working environments
Allowing the special qualities of the timber construction process to be used to best effect
Project considered as a whole with support throughout
Innovative and durable PU materials that are maintenance-free and fully recyclable.

Sound mainly propagates through the sides of the modules. Using elastic bearings means we have been able to almost completely eliminate sound transmission between the individual modules.
