Ring wooden buildings are history


Properly planned wooden houses are comfortable and healthy to live in, and sound insulation has a high priority. A good example of this is the "sue und til" development in Winterthur with over 300 apartments. Its residents are very satisfied with the building acoustics.

Ring wooden buildings are history

In the past, wood was more ring-hard than concrete. Today, timber construction meets the sound insulation regulations without any problems. The most important element is multi-layer with good separation of the individual layers. They interrupt the sound bypasses. Good sound insulation also requires heavy, but flexible but flexible layers.

The"sue und til" residential building is a good example
In the case of the "sue und til" residential building, the raw wooden ceilings were covered with 8 cm thick chippings. This raw ceiling weighting insulates the disturbing disturbing sound components of walking noises effectively. Suitable are fillings with a mass per unit area of 120kg/m2 or more. Because of the good results with this system, Timbatec has been doing without wood-concrete composite ceilings for years.

In the report "Living quietly - even in large buildings made of wood". in the newspaper of the Swiss Homeowners' Association you will find a article on sound insulation using the example of the "sue und til" residential development.

Timbatec offers an all-round package
Timbatec is a leader in the planning of complex timber construction projects. We guarantee an all-round package and therefore have competencies beyond pure structural design. An increasingly important topic is building physics and related sound insulation. We plan good sound insulation concepts for our customers and test them with sound measurements. Thanks to quality assurance, we can continuously develop our designs.

Sound measurements with the Japanese ball
We have our finger on the pulse of time in building acoustics measurements. We carry out sound measurements not only not only with the hammer mill as a sound source, but also with the Japanese ball. This reproduces the low tones with frequencies below 100 Hz well. This is an important quality assurance tool for us. Because: With the standard hammer mill the measured values are reproduced according to the standard, but building users may be disturbed by low may feel disturbed by low tones despite the fact that the measured values are fulfilled.
