Noise-Reducer® Acoustic Barrier
The Noise-Reducer® Acoustic Barrier is a lightweight construction with a high insulation and absorption value. The outer side of these acoustic barriers has on one side a layer of absorbent mineral wool, finished with several layers of mesh. These prefab panels form an ideal acoustic barrier for locations directly alongside roads, railway lines, industrial estates or as a protection against noise coming from machines and airco systems. The acoustic barriers can as option have plants growing on them. The Noise-Reducer® system is a Dutch invention and is produced entirely in the Netherlands.
