At the Schultenkamp development area in Kirchhellen, we are erecting a 150-metre-long and up to three-metre-high noise barrier: RAU® Climatewall. This is a climate wall that is being built as a combination of noise barrier and noise protection wall, sustainably and ecologically. A special feature of this green wall is the fact that approx. 98 percent of the material required can be obtained directly on site of the construction project.
