The DucoGrille NightVent is a glass-replacing ventilation hatch (for glass thicknesses from 24 to 48 mm) protected from outside by an aesthetic window ventilator, with the option of an intrusion-resistant version. Thanks to the flat inside panel, this system boasts a sleek design.

A new feature of the DucoGrille NightVent is the ventilation hatch control, which can now be done with manual or fully automatic operation. In addition, the DucoGrille NightVentcan be connected to a building management system (BMS).

In addition, the outside grille is also available in a vandalism-proof or burglarproof version.
