A highly absorbent free-standing acoustic panel for temporary acoustic enclosures and acoustic barrier constructions for both internal and external applications.
The panels consist of a pre-lacquered metal sheet of 1mm thickness (light grey similar to RAL 9002) with a 70kg/m³ acoustic infill, covered with a black scrim tissue facing, behind a 0.5mm multi-perforated sheet.
Acoustic isolation Rw(C;Ctr) = 32 (-1;-6) dB. Please note that this figure is from laboratory tests with a sealed panel. With external use the insertion loss will be less due to environmental conditions.
With this modular system there is no need for expensive bespoke manufacture. Enclosures or barriers can be constructed on site using the modular sections which are easy to configure.
The perforation percentage for the face of these panels is 28%. Each panel has five different kinds of perforations dia. 3, 4, 5, 6 and 7 mm.
