Living at Baumhaus Mauren

The „Baumhaus“ Residential multi-family building in Mauren, Liechtenstein that serves as an outstanding example of modern timber construction from both an architectural and acoustic perspective. The building was created by Dietmar Marxer (Marxer Metallbau AG) in close cooperation with Denkfabrik AG and Legna holz.werk AG. Comprising five premium 3.5-room flats with spacious balconies, the load-bearing structures of the residential storeys are made of solid CLT timber, while concrete was used for the stairwell and underground car park. This construction method offers environmental and structural advantages but places special demands on sound control.

The challenge of the project lay in finding the right sound insulation and vibration isolation for the lightweight timber ceilings and walls. To provide a level of comfort comparable to that of a solid construction, Getzner Werkstoffe decoupled the floor using a system that offers two degrees of freedom. This system combines GREI impact sound insulation, elastically bound chippings, AFM 35 and cement screed to form a high-performance unit. Targeted use was made of Sylodyn® strips to decouple flanking noise. The system was harmonised and validated to a high degree of precision based on simulations and measurements in the lab and field.

Multi-family timber building

The challenge

The challenge of the project lay in finding the right sound insulation and vibration isolation for the lightweight timber ceilings and walls. Building acoustics play a key role in timber construction. Vibrations are easily transmitted throughout the building, and footfall and flanking noise in particular have a detrimental effect on quality of living. Disruptive noise is noticeably reduced thanks to effective impact sound insulation and an elastic bearing between the wall and floor designed to minimise flanking noise.

Innovation

The solution

To provide the quality of living offered by a solid structure, Getzner Werkstoffe decoupled the floor using an innovative system that offers two degrees of freedom as well as decoupling flanking noise via Sylodyn® strips. The solution was installed on an area measuring around 350 m² in the CLT ceiling. Thanks to its modular construction, the system can be flexibly adapted to different ceiling structures and building types.

Durability

Sustainable protection

In addition to its technical performance, the solution also offer impressive quality in environmental terms. The combination of a solid timber construction and permanently elastic materials guarantees a durable, maintenance-free and resource-efficient structure. The result is a modern living concept that combines a high level of comfort, sustainability and innovative technology.

Sound control

The application

Our high-performance timber construction solutions are based on the durable polyurethane materials Sylodyn® and AFM as well as patented products made from recycled rubber, creating system solutions that deliver optimum sound control.

Impact sound Insulation

What we refer to as impact noise is caused by the use of rooms. The sound radiates via the floor into adjacent rooms and other floors of the building, where it is perceived as a disturbing noise. For example, parquet flooring in neighbouring apartments can lead to a significant impairment of the quality of life. However, effective impact sound insulation can minimise noise propagation and significantly improve architectural acoustics without making it necessary to accept restrictions in the choice of floor covering. Structural sound insulation is essential, especially in buildings that are used for a variety of purposes. With the right impact sound insulation, noise can be effectively avoided and the quality of life noticeably improved.

Sylodyn® bearing strips

The joint insulation Kij plays a key role in the transmission of flanking sound. It provides information about the acoustic coupling of a component joint. If the right decoupling version is used, there may even be no need for a dry lining.

Here Sylodyn® is characterised by its dynamic properties and durability. It is resistant to moisture, oils and greases commonly found on construction sites and has proven itself both in real-life applications and at testing institutes for decades. All this makes it the ideal bearing material for joints.
