MB-SR50


The mullion-transom curtain wall

Thanks to the rich offer of profiles, the architects and designers designing enginners may realize even the most bold concepts as regards the aluminium-glass structures.
 

The system is intended for constructing and creating the light-weight curtain walls of hanging and filling type, as well as roofs, skylights and other structures.
The shape of mullions and transoms allows building aesthetic facades with visible narrow dividing lines, ensuring the structure durability and resistance at the same time. Additionally, the profiles have rounded external edges, what gives the so-called soft-line effect.

The large number of mullions and transoms available in this system guarantees the best possible aluminium use. The economic profiles were obtained by optimization of the intersection shape and by selecting the optimal wall thickness. At a very high load, all mullions may be additionally reinforced with typical internal aluminium profiles, increasing their resistance. The simple profile processing lowers the workload and eliminates all types of carvings at the side surfaces of the mullions.

Application of the thermal break made of insulating material HPVC and the glazing gaskets made of EPDM allows achieving the appropriate class of thermal insulation.

Thanks to the sandwich structure of the lintel-window sill strip, in which the non-flammable materials such as mineral wool and plaster boards are used, the fire resistance classification was obtained depending on the construction of F0.25(EI15)NRO, F0.5(EI45)NRO.
For construction of the broken walls in horizontal and vertical section, the special overlay profiles as well as appropriately shaped clamping and cover beads are available, what eliminates the restrictions in shaping the building mass as well as the necessity to use special angular mullion. The accessories delivered with the system, aluminium supporting elements and connectors fixing the wall to the building surface are made of AlMgSi0.5F22 aluminium alloy.

In facades based on the MB-SR50 system, various shapes of cover beads can be applied. The aesthetic variation of this is the so-called horizontal and vertical line, where the horizontal or vertical divisions are emphasized. This system constitutes the base also for other solutions: “semi-structural” wall MB-SR50 EFEKT, the “Industrial” type of façade, structures applied with the overlay method on the supporting wood or steel framework (MB-SR50 A). In all those variants, apart from standard opening elements, it is possible to use skylight windows and tilt windows, basing on the structural wall system MB-SG50.
