Glass-replacing ventilation hatch with manual or electronic operation.
Window glass replacement ventilation.
A glass-replacing ventilation hatch (for glass thicknesses from 24–48 mm) which provides efficient cooling of any building due to the supply of large ventilation flow rates. It consists of a single module, although it contains two essential components. Ten-year warranty.
From outside, the DucoGrille NightVent is protected by a window louvre with perforated louvre blades (DucoGrille Solid 30Z P1) that act as an insect screen. On the inside, an insulated opening panel with a flat-finished inner panel makes for easy integration into the interior. In addition, the acoustic attenuation ensures that the thermal value of the ventilation hatch is comparable to that of a closed window.
The ventilation hatch can be hinged horizontally or vertically and the inner and outer panels can be finished in various colours. It is available in motorized and manual versions and has been tested under the applicable European regulations by means of intensive tests covering wind and water resistance. In addition, the external louvre grille is also available in a vandal-proof or intrusion-resistant version up to RC2 class.
Applications:

Product Options | Operation: – Electric: An electric actuator can open/ close the ventilation hatch via a wired or wireless user controller, or fully automatically based on CO2 and temperature measurements (if used in a Duco Tronic (Plus) System). The ventilation hatch can therefore be opened at any time, even if no one is in. In addition, the DucoGrille NightVent can be linked to the building management system (BMS). Finish/ Colour:
