Kokowall® HA-Minwol Noise Barrier

The Kokowall® HA-Minwol Noise Barrier is ideally suited as a noise barrier for industrial estates, locations directly alongside roads, around machines and other situations where plant growth is either not possible or desirable on both sides. Kokowall® HA-Minwol is a noise barrier where one side has been finished with durable coconut fibres and the other side finished with a layer of mineral wool with a plastic and galvanized mesh. 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.
