DucoGrille Acoustic G 150
DucoGrille Acoustic G 150
The DucoGrille Acoustic G 150 is a sound attenuating built-in wall grille, crafted from extruded aluminium profiles. The louvre blades are locked into place fast and easily on plastic blade holders, and are fitted with sound-attenuating, non-combustible mineral wool on the inside. Thanks to its solid construction, the DucoGrille Acoustic G 150 has a high damping value and a low resistance factor (and consequently a better flow rate).
