Climatewall Ilmenaugarten
The RAU® Climatewall Ilmenaugarten - Sustainable noise protection with exemplary character
The RAU® climatewall was erected over a length of 850 m and a height of 4 m between the Ilmenaugarten development area and the adjacent railroad line. The modular, trapezoidal noise barrier uses local excavated material and does not require deep foundations.
Rail traffic is a significant source of noise – especially in residential areas, this can lead to health problems such as sleep disorders and stress. In order to permanently protect the new Ilmenaugarten residential area from the effects of rail noise, an innovative, sustainable noise protection solution was implemented: the RAU® climatewall – an ecological overall concept with outstanding acoustic properties.

Type of project
Construction of a RAU® climatewall in Ilmenaugarten
Project start and completion
2016
Job details & challenges:
The aim was to construct a high-performance noise barrier while taking ecological, urban planning and economic aspects into account. The challenge was to achieve highly efficient noise protection without massive foundations – while at the same time reducing CO₂ emissions and allowing complete greening.
Project objective:
Construction of a sustainable noise protection system to reduce health-relevant noise emissions from rail traffic, with simultaneous promotion of biodiversity, climate protection and integration into the landscape.
Results
- Flexible implementation along the railroad line, taking into account limited space, varying ground conditions and ongoing construction activities in the new residential quarter.
- Effective noise protection for daycare centers, senior centers and residential buildings with sound insulation up to 68 dB and sound absorption of 20 dB.
- Modular system enables rapid, low-disturbance assembly without deep foundations - ideal for dynamic construction environments such as Luisenglück.
- Use of 98% local excavated material saves resources, reduces CO₂ emissions and promotes a sustainable circular economy
- Green wall surfaces improve air quality, support the microclimate and integrate into the design of the new neighborhood.
- Robust, UV-resistant materials guarantee a service life of 60-80 years with minimal maintenance.
Conclusion:
The RAU® climatewall in Ilmenaugarten is a pioneering example of how modern noise protection, sustainability and quality of life can be harmonized - a strong signal for the mobility turnaround and the responsible use of the environment and resources.
