Perforation - Achieving visual and acoustic effects

Metal ceilings can be perforated for visual and acoustic reasons. Depending on customer wishes, round, angled or slot-shaped apertures can be selected in various configurations and in a range of different sizes. This makes it possible to create a vast array of different looks.

A primary benefit of perforations in metal ceilings is the resultant improvement in room acoustics. Sound passes through the perforation holes into the absorption material behind the metal ceiling (e.g. acoustic fleece, mineral wool or foam) where it is then absorbed. Furthermore, speakers or ventilation systems can also use the free cross section of these perforation holes.

Please note that, with very small hole diameters of < 2 mm and very small web components and/or large free cross sections, visual effects can occur where the surface appears to start flickering.
