With the slim RAU ROCK EXTENSIV noise protection wall, a pre-assembled element is transported to the place of use and embedded in the existing steel girders like a standard wooden or aluminum element. The surface of the elements cannot be distinguished from one of the other variants. Only the horizontal bed joints make the difference clear.
This model enables a minimum width of 13 centimeters and is therefore extremely versatile. Combinations with other walls are also possible at any time.
