Are resistant to temperature, UV- and ageing, absorb dynamic loads and, with a linear thermal transmittance of 0.064 W/(mK), also have excellent thermal insulation properties.
As an extra precaution, families with small children may want to have additional protection against unwanted opening of the window by children. The special tilt-before-turn mechanism ensures that children can only tilt, and not open, the window. The window can only be opened all the way with a key.

This hardware component provides for partial ventilation. Arresting the sash with the preset gap of 5 mm stops the window from slamming shut.
Issues an alarm by emitting a loud acoustic signal when the pane is broken and hence startles before break-in attempts. False alarms are prevented by a dual sensor mechanism (vibration and frequency).
The glass panes are bonded to an extremely tough, tear-resistant plastic film that not only ensures the glass is very unlikely to break. Even if the pane were to break the fragments would adhere firmly to the film. And even then it would take a lot of time, effort and tools to penetrate the pane. A higher security class can be achieved by increasing the number of plastic films and glass panes.
The lockable handle prevents movement of the hardware and makes it harder to open a broken window by reaching in from the outside. In everyday use it serves as a childproofing means.

The Regel-Air ventilation system is a self-regulating system that is installed in the upper section of the window and can be retro-fitted if required. Fresh air supplied from the outside flows laterally over the narrowing seal in the window rebate. In normal operation the preheated air then rises preheated between the sash and the frame through the ventilator below the ceiling into the room. In stormy weather or strong winds the system automatically stays closed, thereby preventing draughts. The Regel-Air has a flow rate of 2.1 m3/h at 4 Pa. Additional benefit of the window rebate ventilator: It shuts out noise, the device can achieve high acoustic insulation values up to acoustic protection class 4 (= 42 dB).
