The MB-SR50N mullion-transom curtain wall is one of Aluprof’s most popular products. Thanks to its exceptional versatility, it has become a bestseller among façade systems. It has been used in the construction of many landmark projects, including the National Stadium in Warsaw and the distinctive terminal of Kraków Airport. The system also features in some of the most recognisable shopping centres and office buildings in Poland’s largest cities.

MB-SR50N combines elegance with outstanding functionality, making it an excellent choice for project owners, architects, and fabricators alike. Its adaptability enables the creation of stylish and durable façades that meet the highest quality standards.

MB-SR50N – ignite your imagination

The structure of these façades makes them ideal for a wide range of building types, including large, multi-storey or technically complex projects with expansive glazing. MB-SR50N allows for the creation of various shapes and forms, offering architects broad design possibilities when developing unique architectural concepts. Thanks to its refined aesthetics and precise detailing, the system fits perfectly into both traditional and modern architectural styles.

With its slim sightlines, façades built using the MB-SR50N system have a minimalist appearance while maintaining impressive strength. The option to align transoms and mullions on the interior side creates a uniform grid that is both attractive and durable. This feature also simplifies aesthetic and precise connections with other structural elements such as internal walls and suspended ceilings.

A wide range of profiles ensures versatility in load-bearing capacity, withstanding up to 1,100 kg for fixed façade modules. Innovative accessories and connectors enable flexible positioning of fixing points and easy integration with various window and door types, including tilt and roof windows. This gives designers and builders extensive creative freedom to develop bespoke and innovative solutions tailored to each project’s needs.

The use of HPVC thermal breaks and EPDM gaskets ensures very good thermal insulation, while minimising condensation on aluminium components – key to maintaining comfort and improving a building’s overall energy performance.

Aluprof products – unlimited design potential

The system is available in various thermal insulation versions, making it adaptable to specific project requirements. Notably, the MB-SR50N HI and MB-SR50N HI+variants offer enhanced thermal performance. The MB-SR50N system also serves as the base for the MB-SR50N A façade, designed for installation on steel or timber substructures. The visually distinctive MB-SR50N PL version highlights vertical and horizontal divisions, while the MB-SR50N EFEKT version creates a spectacular fully glazed façade using special glass joints. Fire-rated variants (MB-SR50N EI and MB-SR50N EI EFEKT) are also available, providing fire resistance from EI 30 to EI 60.
