Noise barrier with modular panels KOKOWALL® HIGH ABSORPTION

prefabgalvanized steelcoir

The Kokowall® High Absorption Noise Barrier is ideally suited for situations where higher sound absorption requirements are set. The Kokowall® Noise Barrier has a warm look and fits in with every landscape. The Kokowall® noise barriers have an outer layer of durable coconut fibre which allows plants to grow on them. Apart from the considerable noise insulation and absorption the coconut fibres are ideal for the adhesion of various types of climbing plants. A Kokowall® screen is fully overgrown within a few years. The Kokowall High Absorption Noise Barrier is suitable for use along railway lines, residential areas, industrial estates, municipal roads and motorways. The Kokowall® system is a Dutch invention and is produced entirely in the Netherlands. You can read more about the screens below as well as in our brochure.
