Resistance to external factors and no maintenance required
The DXF DU8 flat roof window is distinguished by its simple, non-opening design. This construction ensures tightness, durability and minimises the risk of failure. Multi-chamber PVC profiles filled with thermal insulation material guarantee high resistance to moisture, corrosion and temperature changes. The window retains its full functionality and aesthetics for many years, regardless of heavy rainfall or strong sunlight. It is durable and trouble-free to use, providing constant access to natural daylight, safety, and comfort regardless of the weather.

Practical solution for flat roofs
The DXF DU8 non-opening window is designed for installation on flat roofs with pitches from 2° to 15°. If the roof pitch is less than 2° or it is advisable to increase the installation angle, use the XRD-A angled installation base. For green, gravel or ventilated roofs, use the XRD and XRD/W installation bases, which raise the window above the finishing layers and facilitate proper water drainage. The simple, elegant form of the DXF window fits perfectly with modern architecture. The window can be equipped with internal accessories and an external awning blind to reduce heat build-up.

Glass with steppe
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.
Glazing unit DU8
The DU8 triple-chamber glazing unit is a solution dedicated to challenging projects. Thanks to its exceptionally low heat transfer coefficient of 0.64 W/m²K for the entire window, it effectively reduces heat energy loss. The internal P2A laminated glass ensures a high level of safety, protecting the interior in the case of breakage. The external toughened glass is covered by a lifetime hail resistance warranty, which guarantees durability and reliability in all weather conditions.
Frame
The window structure is based on a frame made of white PVC profiles (RAL 9010) with a multi-chamber design, filled with insulating material. As a result the frame is highly resistant to moisture and cleaning agents, which makes it ideal for rooms with high humidity, such as bathrooms or laundry rooms. The entire structure is durable and requires no regular maintenance, and its light colour scheme makes it easy to match with a variety of interior designs.

Our products stand out for what truly matters. Discover the features that make them reliable and exceptional in everyday use.
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.
