Q & A
The Acoustic Barrier PNB-A sound-absorbing panel consists of two profiled, thermo-lacquered aluminium sheets, both with perforations (absorbent sides). Rock wool with black protective fleece and insulation foil is placed inside the panel between the two aluminium sheets. When joined together, they form a casing which is closed at the ends with a polypropylene cover.
The Acoustic Barrier PNB-A can be adapted to profiles type HEA/B 180.
