Smoke exhaust windows and flaps
The smoke exhaust windows and flaps play a particular role in ensuring safety and comfort for the people staying in the building. When properly selected, they are the elements of gravity ventilation, and when necessary they can help to quickly get rid of smoke and toxic vapours which may be dangerous for health and life. The offer for these products is characterised by the diversity of solutions so they can be used in an individual development, as well as elements integrated with aluminium façades or roof glazed panels. They can be based on window systems such as MB-59S, MB-59S Casement, MB-60, MB-60US, MB-70, MB-70US, MB-86, MB-86US and on solutions dedicated to façades, such as tilt-in windows and roof windows. The smoke exhaust and ventilation system is supplemented by aeration windows and doors.
The smoke exhaust windows and flaps can be equipped with reliable and silent mechanisms by D+H, GEZE, and for roof windows – also with drives by ESCO. Different types of actuators, including drives with a large opening force, are available. They can be installed in a single window or in synchronised “Tandem” systems. In spite of their responsible function in building, these structures can be characterised by high aesthetics, which is ensured by the possibility of using small-sized drives installed parallel to the window surface.
The smoke exhaust constructions based on Aluprof systems have been tested in accordance with EN 12101-2 in IFT and VdS institutes and possess documents confirming the achievement of the required technical parameters.
Fire protection and smoke exhaust systems - General information
A wide range of systems offered by Aluprof facilitate a variety of structural elements that are responsible for “fire protection zones” in buildings, and provide the right conditions for evacuation of its occupants. These solutions include both a window wall & door system option, extending to a typical “stick assembly” curtain wall system solution. The fire resistance performance of these solutions, depending on the project requirements, are available in a variety of classes, from as low as EI 15 (15 minutes) up to a an EI class of 120 (2 hours) for vertical assemblies, and achieve a class of REI 20/ RE 30 for roof glazing.
The following solutions, categorised by their common fire retardant properties, are responsible for the safety of a building’s occupants during a fire: MB-78EI internal & external partition walls & doors (classes EI 15 to EI 90), MB-78EI DPA automatic sliding doors (EI 30), MB-118E fire walls (EI 120), MB-SR50 EI and MB-SR50N EI curtain wall (classes EI 15 to EI 60), MB-SR50 EI EFEKT and MB-SR50N EI EFEKT curtain walls (classes EI60), glazed fire roofs (RE 120/ RE 30), MB-45D smoke-tight door & smoke exhaust windows & valves.
An important feature of the Aluprof fire rated solutions is their ability to interface with each other, one system to the next, whilst maintaining the necessary fire resistance. This is demonstrated with the integration of the MB-78EI door into the MB-SR50 EI and MB-SR50N EI curtain wall, enabling the whole structure to achieve a common EI 30 or EI 60 class performance. The same MB-78EI door possibility exists, with implementation into the MB-118EI wall system.
