Abstract (en)
[origin: EP3162961A2] Design of a sound barrier of the type comprising upright supports or pillars, which are anchored in the ground, wherein there are secured between said supports or pillars elongated primarily horizontally extending shield elements, consisting for example of thin-wall profiled metal sheets and a core of a sound-absorbing granule material or fiber material, characterized in that the granules used are based on recycled glass fiber. The glass fiber has previously been used in wind turbine blades, sailboats, and other non-polluting components. The fiberglass granules which are used are mechanically crushed into pieces varying in length and thickness, and therefore the granules which are used are not homogeneous in size. Costs of stockpiling and further processing are avoided, so that the environmental aspects regarding used fiberglass components can be addressed by recycling of the granules into absorbing material.
