The Echo Barrier H2 Series Sound absorbing barrier is produced using an optimal weight and density of PVC, and are hand stitched to ensure they retain the maximum level of strength. Part of the patent protected technology encompasses a unique waterproof lining on the back of the acoustic fencing barrier. The unique performance of the acoustic foam will therefore not deteriorate as the barriers age and wear. This is particularly useful where the barriers are being used on construction sites, or in extreme weather conditions.
