The DEF DU6 Z‑Wave model allows the sash to open up to 12 cm using the ZRH1 remote control, significantly enhancing everyday convenience. The rain sensor automatically closes the sash during precipitation, protecting the interior from moisture.
The triple‑glazed DU6 unit provides excellent thermal insulation — Uw = 0.7 W/m²K — reducing heat loss in winter and preventing overheating in summer. The toughened outer pane, laminated inner pane (P2A class) and multi‑chamber PVC profiles filled with insulation ensure durability and safety, regardless of weather conditions.

The DEF DU6 Z‑Wave window is designed for installation on flat roofs with pitches between 2° and 15°. If the roof pitch is below 2°, or if increasing the installation angle is recommended, the XRD‑A angular installation base should be used. For green roofs, gravel roofs or ventilated roof structures, the XRD and XRD/W installation bases may be applied, raising the window above the finishing layers and ensuring proper water drainage. The clean, elegant form of the DEF window blends perfectly with modern architecture. The window can be fitted with internal accessories as well as an external awning blind that reduces heat gain.
The D_F flat roof window combines functionality with elegant design inspired by contemporary architecture. The standard version features glass with a black steppe, which emphasises its minimalist character and blends in perfectly with the structure of modern buildings. Additionally, the window is available in the ColourLine version, which allows for personalisation thanks to a wide range of 200 RAL Classic colours, ensuring consistency with the roof colour and the character of the building.

Maximum interior daylighting
Modern buildings with flat roofs do not have to mean limited access to natural daylight, as the use of properly designed windows allows interior spaces to be effectively illuminated. Thanks to specially engineered profile construction, the glazed area can be increased by up to 16%, resulting in noticeably brighter and more comfortable interiors.

Structural durability
Flat roof windows are equipped with advanced glazing units, in which the external pane is made of toughened glass, while the internal pane features P2A safety classification. This solution increases resistance to damage and, in the event of glass breakage, significantly reduces the risk of hazardous fragments.

Year‑round comfort of use
A stable frame made of multi‑chamber PVC profiles filled with thermal insulation material helps maintain proper indoor conditions inside the building. In practice, this results in improved user comfort, especially when replacing older solutions with modern windows offering enhanced performance parameters.
