The MB-SR50N mullion and transom system is designed for the construction and fabrication of light curtain walls, suspended and filling type, as well as roofs, skylights and other spatial structures. In line with the current trends in architecture, it allows for flushing the profiles of mullions and transoms from the inside of the facade and obtaining various versions of the external appearance. This system is also the basis of the version with increased thermal insulation MB-SR50N HI + and fire protection solutions, it is also associated with the structures of various types of windows: tilt-and-slide, roof and integrated with the facade. Thanks to the wide range of solutions based on the MB-SR50N facade, architects and designers can implement even the most daring ideas in the field of aluminum and glass structures.
