Equipped with a laminated P4A class glazing unit and a structure compliant with the RC 2 burglary resistance standard.






In modern construction, it is difficult to imagine a space without natural light. However, many projects face a challenge: how to illuminate interiors under flat roofs while simultaneously ensuring adequate security? The answer is Secure flat roof windows. These solutions combine high burglary resistance with elegant aesthetics and very good insulation parameters. They comply with the European RC2 standard, which means that they have been designed and tested for resistance to forced entry. The range includes both fixed and opening models, as well as variants with flat glass segments or transparent domes. This makes them suitable for a variety of needs – from private homes to commercial buildings and public facilities.
The most distinctive feature of Secure windows is their security. Each model is equipped with anti-burglary solutions that meet the requirements of RC2 class. This means that the window effectively resists attempts to break in using hand tools that a potential burglar might have at hand. The P4A laminated glass plays a key role – even if broken, it remains attached to a special film, making access to the interior difficult. The external toughened glass provides additional protection for the entire structure and comes with a lifetime warranty against hail damage. Some models also feature polycarbonate domes, a highly mechanically resistant material that withstands changing weather conditions and does not degrade under the influence of UV rays. This combination not only protects household members from energy loss and rain, but above all gives them a sense of security in their own homes.
Secure windows are designed to maximise interior lighting. Thanks to specially profiled frames, the glazing area is up to 16% larger than standard solutions. This means rooms become brighter and more user-friendly. This is particularly important in places where it is not possible to install traditional vertical windows, such as bathrooms, corridors or utility rooms under flat roofs. Models with the DU6 glazing unit offer a Uw coefficient of 0.7 W/m²K, which makes them suitable for energy-efficient buildings. Versions with the P4 glazing unit, on the other hand, achieve a Uw = 1.2 W/m²K and additionally provide acoustic insulation of Rw 35 dB, improving comfort in areas exposed to outside noise. Regardless of the option chosen, users gain a bright, warm, and safe interior.
Another advantage of Secure windows is that they can be installed in various conditions. Type C models can be installed on flat roofs with pitches from 0°, while type F versions are designed for pitches from 2° to 15°. For green, gravel or ventilated roofs, 15 cm high XRD or XRD/W bases can be used to raise the window above the finishing layers and facilitate water drainage. This solution gives designers and investors a great deal of freedom – Secure windows can be used in modern private homes as well as in office buildings, hotels and public buildings. In addition, the offering includes a wide range of sizes – from 60×60 to 120×220 cm – and is fully compatible with FAKRO internal and external accessories, allowing the window to be tailored to specific user requirements.
Secure windows are constructed using multi-chamber PVC profiles filled with thermal insulation material. This solution not only reduces energy loss, but also provides high resistance to moisture and cleaning agents, which is important in rooms such as bathrooms and laundry rooms. The DU6 glazing unit is a set of three panes of glass with two chambers filled with argon, achieving a Ug coefficient of 0.5 W/m²K. The P4 glazing unit, used in models with a polycarbonate dome, combines toughened glass with P4A laminated glass and also meets RC2 requirements
