The presented roof window belongs to the MB-SR50N system and is used to fabricate smoke exhaust vents. Windows of this type are designed to be fitted on roofs with inclination angle ranging between 5° and 75° in relation to the horizontal line. Maximum width of the window can reach 1.80 m, its height – 2.05 m, and the max. total area of the glass pane is 3.40 m2. The weight of the window is limited by technical parameters of opening mechanism and hinges and can reach 150 kg. The construction can be glazed with 24-32 mm thick glazing units.
The roof window is a modern construction that features a number of advantages. Three-chambered, load-bearing aluminium profiles insulated with appropriately high thermal breaks, guarantee proper resistance, thermal insulation and rigidity. Thanks to the shape of profiles and the compact construction, the window does not visibly protrude above the roof surface. Weather stripping on the external side constitutes eaves for rainwater and the inner part is brought to the glass pane as close as possible to facilitate water outflow. Hinges are hidden in the profiles to avoid exposure to weather conditions, which significantly prolongs their life cycle.
The roof window is equipped with highly efficient drainage and ventilation system connected with the mullion/transom wall system MB-SR50N. To ensure highly effective tightness to rainwater penetration, there has been applied the sealing system of the newest generation made of cellular EPDM.
The window on the inside is equipped with a special aluminium groove used to collect water from the internal side of the glass pane.
MB-SR50N RW has been adapted to a wide range of closers available on the market and windows made from this system can be used as smoke exhaust vents.
