Smoke extraction in case of fire and daily ventilation
For rooms with increased humidity
Chain actuator for automatic opening
Suitable for installation in pitched roofs with a slope of 15°–90°
Smoke ventilation window FSR-U P5
The FSR‑U P5 smoke ventilation window combines fire protection functions with the convenience of everyday use. In emergency situations, it effectively removes smoke and hot gases, increasing the safety of people inside the building. On a daily basis, it functions as a roof window, allowing for natural ventilation and daylight access, thereby enhancing indoor comfort. The solid wooden construction, high‑quality finish, and P5 glazing unit make the FSR-U P5 model an ideal solution for stairwells, public buildings, and any locations where reliability and enhanced burglary resistance are essential.
Construction designed with safety in mind
The FSR‑U P5 model has been designed to ensure maximum smoke extraction efficiency while maintaining stability and full operational control. The 24 V chain actuator opens the sash to an angle of 90° within 60 seconds, achieving the optimal geometric smoke extraction area in accordance with PN‑EN 12101‑2. Such a wide opening also allows the window to be used as a safe roof exit in emergency situations. Robust hinges and a precision‑engineered mechanism ensure structural stability even under high loads, while compliance with VdS 2221:2001‑08(01) enables use in gravity smoke ventilation systems for stairwells.
Flexible installation in vairous roof slopes
Installation of the FSR‑U P5 smoke ventilation window is possible in roof slopes with pitches from 15° to 90°. This wide installation range makes the window suitable for both pitched roofs and more demanding structures. A wide range of flashings is available, allowing for perfect adaptation to various types of roof coverings. The window can also be complemented with additional components such as weather sensors, ventilation switches and remote control systems. This enables flexible adaptation to the technical requirements of a specific building while ensuring comfort in everyday use.
Glazing unit
The FSR-U P5 smoke ventilation window is equipped with an anti‑burglary, double‑chamber P5 glazing unit, providing a high level of protection against forced entry through the glazing. The internal laminated pane, class P2A, enhances user safety – even if broken, the glass pieces remain stuck with the film, reducing the risk of injury and preventing unauthorised access. The external toughened pane, covered by a lifetime warranty against damage caused by hail, increases resistance to mechanical damage and weather conditions.
External cladding
The external elements of the smoke ventilation window are covered with durable, corrosion‑resistant flashing in RAL 7022 colour. The materials used offer high resistance to moisture, UV radiation, and varying weather conditions, ensuring long‑lasting protection and an aesthetically pleasing appearance. The elegant finish harmonises perfectly with both modern and traditional roofing materials. In combination with a suitable flashing, it provides a tight and durable connection with the roof, even in buildings subjected to intensive use.
Internal finish
The interior of the smoke ventilation window is made of high‑quality pinewood, vacuum‑impregnated to protect it against the growth of fungi and mould. It is additionally coated three times with polyurethane lacquer, which creates a durable, moisture‑resistant and perfectly smooth white finish. The absence of visible grain highlights a modern, minimalist style. This type of finish is ideal for kitchens, bathrooms and all areas where aesthetics and functionality are equally important.
Chain actuator
The 24 V chain actuator used in the FSR-U P5 model enables automatic opening and closing of the smoke ventilation window when connected to a control system. The mechanism is designed to ensure fast operation – full opening to an angle of 90° is achieved within 60 seconds. Stable lifting of the sash and high reliability in emergency situations ensure full functionality both in smoke ventilation mode and during everyday use.
