Flat roof window DXF DU6 Secure
A solution designed for places where user comfort must go hand in hand with a high level of security. The DXF Secure window meets the requirements of European class RC2, offering increased burglary resistance without compromising on functionality and aesthetics. The DU6 double-chamber glazing unit with P4A class glass effectively protects against break-in attempts, and the toughened outer glass comes with a lifetime hail resistance warranty. PVC profile technology with thermal insulation reduces energy loss and maintains a comfortable temperature inside the building.

Comfortable use in a secure environment
Specially designed profiles allow for up to 16% more glazing area than standard solutions in this category. This allows for better daylighting of the interior, which will be particularly appreciated by users in spaces where vertical windows cannot be used. The window has no moving parts, simplifying its operation and increasing its tightness, thus eliminating the risk of failure. The aesthetic finish makes the solution suitable for both residential and commercial interiors.

Tailored to modern roofs
The window is designed for installation on roofs with pitches from 2° to 15°. However, for green, gravel or ventilated roofs, it is possible to use an additional XRD or XRD/W installation base to increase the installation height. Dimensions can also be customized within the range of 60×60 to 120×220 cm. An additional advantage is full compatibility with internal and external accessories, allowing the solution to be tailored to specific user needs.

Glazing unit
The DU6 glazing unit is a three-layer structure consisting of a double-chamber insulated glass unit with a total thickness of 48 mm. The inner laminated glass with P4A resistance class ensures an increased level of security in accordance with the requirements of RC2 according to EN 1627, providing a significant anti-burglary barrier. The glazing cavity is filled with noble gas (argon), which, in combination with low-emission thermal coatings, enables a heat transfer coefficient of Ug = 0.5 W/m²K to be achieved, and for the entire window Uw = 0.70 W/m²K (in accordance with EN 14351-1). The DU6 glazing unit design further eliminates thermal bridges, reducing heat loss even in extremely low temperatures.
External glass
The external toughened glass is the primary protection element in the DU6 glazing unit and is designed in accordance with EN 12150. It is characterised by high mechanical strength and resistance to dynamic impact, confirmed by a lifetime hail resistance warranty. This glass has undergone a controlled thermal toughening process, increasing its strength to a level that allows it to be installed in areas exposed to intense environmental impact. It is 6 mm thick, and carefully selected TPS spacers maintain the high edge tightness of the glazing unit.
External cladding
The steppe type external cladding is a prefabricated glass and aluminium segment that forms an integral part of the upper window structure. It consists of toughened flat glass and an aluminium profile in RAL 9005, permanently joined into a frame. This segment not only serves an aesthetic function, giving the window a minimalist look, but also affects light efficiency thanks to the appropriate glazing geometry. The flat surface eliminates areas where water and dirt can accumulate, and the seals used ensure a durable connection with the roof covering. The design of the steppe segment maximises the lighting area, increasing light transmission by up to 16% compared to standard solutions.
