Metawell® Alu-Silent (sound reduction) Metawell® Alu-Silent is a patented aluminium sandwich panel, which has an enormous sound insulation in terms of weight and panel thickness. The high sound insulation is realized by a special sand filling, which is filled into the corrugated channels of the Metawell® panel. The good static values and the high fire ratings of the well-established Metawell® panels are preserved or even improved. Different panel types are offered.
