Flat roof window DMF DU6 Secure
The DMF DU6 Secure flat roof window was designed for investors looking for a combination of increased security, energy efficiency and comfort of use. This model is manually opened using the included ZSD rod and is suitable for roofs with pitches from 2° to 15°. It is ideal for rooms where standard vertical solutions are impossible and where natural lighting and burglary protection are of key importance. The Secure version complies with European resistance class RC2 according to EN 1627.

Safe access to light
This model features a specially designed DU6 glazing unit, in which the internal P4A class laminated glass effectively increases resistance to forced entry, ensuring a higher level of burglary protection. At the same time, the window retains high daylight transmission – the glazing is up to 16% larger than in comparable designs, resulting in brighter, more pleasant interiors. This is an option for people who want to feel safe in their home without having to compromise on aesthetics or comfort.

Tailored to your needs
The DMF DU6 Secure stands out for its excellent thermal insulation properties – the heat transfer coefficient for the entire window is Uw = 0.70 W/m²K, and for the glazing unit alone Ug = 0.5 W/m²K. The set of three panes is filled with noble gas (argon), further improving thermal efficiency. The window is also equipped with three independent seals and an external toughened glass with a lifetime hail resistance warranty. The possibility of mounting on 15 cm high XRD or XRD/W installation bases allows for installation on green, gravel or ventilated roofs.
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.
