The importance of window automation systems in natural interior ventilation
In many projects we can find impressively sized windows that provide sunlight, but due to their size or limited accessibility they are not opened later. Especially today, when there is so much talk about the need for regular ventilation of rooms, it is worth taking care to preserve the full functionality of windows already at the design stage. A solution that allows convenient and safe opening of virtually any type and size of woodwork are D+H window drives.
The operation of window drives can be seen on the D+H Polska channel on Youtube.
Automated window ventilation
Natural ventilationsystems, or automated ventilation using windows, most often use chain drives. They can be surface-mounted or mounted inside the window profile. The actuators are used in both small and large buildings, where synchronization of window opening is required, for example, in cycles or at specific times.

Application of window drives
Windows installed too high, due to their location are most often not opened at all, they are only a source of light. We encounter such a situation in many projects, with even where air conditioning is used, such as in office buildings, it is worthwhile to ensure access to fresh air. Ventilation has become particularly important during the pandemic period, when there is more and more talk about the need for regular air exchange in closed rooms with large numbers of people. Access to fresh air also translates into better mood and ability to concentrate.
Thus, the role of window automation is not only to restore full functionality to hard-to-reach windows, but also to increase ventilation efficiency thanks to the programmability of the drives. An additional benefit is the safety of this solution, which is particularly important, for example, in schools or multi-story buildings, where it is not possible to use windows with a traditional handle.
Smart home application for managing D+H window automation systems
The main benefits of using window drives:
- ability to open windows that are difficult to access,
- automated, efficient ventilation,
- convenient opening of windows with a button, remote control or application
- possibility to configure window operation with building management system, external wind/rain sensor or internal humidity and temperature sensor
- safe opening of windows (limiting the possibility of opening to the reveal)
The most frequently selected D+H window automation systems
The choice of actuator models for D+H windows is large, but for the purposes of natural ventilation , the most common are the VCD or CDC series, which allow the window to automatically tilt, swing and tilt, or in situations where you want the window to also open to the reveal - the BDT-Advanced window hardware actuator.

VCD - compact drives for windows
The VCD series are affordable, compact chain drives that we can use in virtually any type of woodwork - in plastic, wood and aluminum windows. This is an excellent solution for windows that are difficult to access, but also wherever we want to better utilize the space under the window. Opening and closing of the sash is controlled by a button mounted on the wall, a remote control or an app. As standard, the actuators come in silver, but there is the possibility of painting them in any color so that they do not stand out against the woodwork.

CDC - slim design and extremely quiet operation
The CDC series actuator is a real innovation in window automation. It is characterized by a slim housing and extremely quiet operation, so that the operation of windows is not only automated, but also discreet. CDC drives can be surface-mounted or mounted inside the window profile. The use of CDC series drives allows the opening of tilt, turn and tilt windows. As with the VCD series drives, it is possible to paint the drives to match the color of the window joinery.

BDT-Advanced - opening to the reveal
The BDT-Advanced drive is mounted on the window sash, in place of the traditional handle. Power is supplied through a wire led inside the profile. Control can be carried out from the touch panel on the drive housing, using a remote control or an app on a phone. The functionality of the window is similar to that of a traditional handle - it can be tilted, opened ajar, closed and locked. The differences are due to the benefits of automation, such as the ability to ventilate by setting the window to open cyclically at preset intervals.

Selection of suitable drives for windows
To select the right automation system from the CDC and VCD series, you can use the calculator for selecting drives for natural ventilation at www.napedyokienne.pl. It is enough to specify the basic parameters of the window and the preferred method of mounting the drive (surface or inside the profile) to receive a list of specific models of drives and the necessary mounting consoles.
