Thermally insulated, sound attenuating acoustic “glazed-in” ventilator. The GlasMax (ZR) offers significantly better sound-damping values when compared to standard ventilators, making it ideally suited for situations associated with low sound exposure levels. The ventilator allows a combination with the DucoMax (ZR) sound absorbing ventilators in projects with noise-exposed façades and light noise exposed façades. The (optional) self regulating ventilation flap provides a significant net energy gain. The removable inner grille performs as insect screen and is easy to clean.
