Acoustic screens are particularly needed on roads and railways to alleviate the propagation or reflection of unwanted noise. For its noise barriers, MICE Infracoustics uses perforated aluminium panels with a thickness of 1.5 to 2 millimetres, which are perforated in zones. These elements often have to be embossed for design reasons or because of the mechanical requirements for rigidity. After forming, the surface of the element is finished with a powder coating. The ready-to-install elements are up to 6,000 millimetres long and have different widths.
"We need reliable delivery of ready-to-install, individually manufactured perforated metal sheets in large quantities, measured in thousands of square metres, in consistent quality. Consultancy as a service is also important to us. We now have a long-standing, trusting relationship with SCHÄFER Perforated Metal, having successfully completed a number of projects together," explains Pierre Letawe, Project Engineer at MICE Infracoustics in Belgium.
Different versions of acoustic panels are required for each application, whether in existing buildings for noise remediation or in new buildings with strict noise restrictions. Examples of realised projects can be found, for example, in Mechelen (Belgium), with 3,000 square metres of metallic acoustic screens for sound absorption of reflections on the wall, or in Alleur (Belgium) as well as in Dudelange (Luxembourg), to prevent the propagation of road noise in housing estates.
