Flat roof window DMC-M P4 Secure
The flat roof window in the Secure version has been designed for users who expect a high level of safety while maintaining excellent performance characteristics. This model combines anti‑burglary, energy‑efficient and aesthetic solutions, making it suitable for both residential and commercial buildings. The product meets the requirements of the European RC2 resistance class in accordance with EN 1627.
Security and illumination in one
The window is equipped with a single‑chamber P4 glazing unit featuring an inner laminated pane of class P4A, providing effective protection against forced entry. The outer toughened pane is resistant to hail, which is confirmed by the manufacturer’s lifetime warranty. The matte polycarbonate dome ensures efficient daylight transmission, while specially designed profiles allow for up to 16% more glazing surface compared to standard solutions.
Tailored to your needs
The DMC‑M P4 Secure model is designed for installation on roofs with pitches between 0° and 15°. A 15 cm XRD or XRD/W installation base can be used to raise the window when installed in green roofs, gravel roofs or ventilated roof structures. The system also allows the installation of both internal and external accessories, increasing the overall functionality of the entire setup.

Dome
The external window cover in the form of a transparent dome is made of durable polycarbonate – a material with high resistance to mechanical impact and changing weather conditions. Polycarbonate is characterised by low weight while maintaining high rigidity and structural durability, reducing the load on the roof structure. The dome has double-sided UV protection coatings that protect its surface from tarnishing and degradation. The transparent form ensures optimal daylight transmission while reducing the penetration of harmful radiation. The factory-fitted dome is an integral part of the window, increasing the tightness of the entire structure.
Glazing unit
The P4 glazing unit used in the window is a single-chamber construction consisting of a set of panes marked 4H – 14 – 33.4T. This unit is filled with noble gas (argon), which further enhances its thermal insulation properties. The internal P4A class laminated glass provides protection against burglary attempts and meets the requirements of European resistance class RC2 according to EN 1627. The glazing unit achieves a heat transfer coefficient of Ug = 1.0 W/m²K, while the total coefficient for the window is U = 1.2 W/m²K, which proves its high energy efficiency.
Characteristic features
Our products stand out for what truly matters. Discover the features that make them reliable and exceptional in everyday use.
Interior lighting
The use of polycarbonate domes allows natural light to be effectively brought into rooms located under a flat roof. The transparent surface and protective coatings reduce UV radiation penetration and maintain the product's aesthetic appeal for a long time.
Safety of use
Toughened external glass and P2A class laminated internal glass provide effective protection against mechanical damage, including hailstorms. The design of individual models meets high standards of durability and resistance, which translates into reliability in difficult weather conditions.
Energy-efficient design
PVC profiles with thermal insulation filling and carefully selected glazing units reduce heat loss, supporting thermal comfort in the building. The insulation parameters reach levels suitable for both standard construction and houses with increased energy requirements.
