USG sound-absorbing transfer air grille

The sound-absorbing grille USG was designed specifically for preventing the transmission of sound, especially speech, between doors or partitions. The grille is suited for usage as a return air or transfer air grille. The grille consists of extruded aluminium profiles lined with micro-acoustic material on the inside. Screws are attached through the frame (USG-40 with patented screws).
