The MB-SR50N façade system: A modern solution for lightweight structures
MB-SR50N façade is designed for the construction and execution of flat, lightweight curtain walls of suspended or infill types, roofs, skylights, and other structures.
The design of mullions and transoms creates aesthetic façades with narrow, visible division lines. It ensures structural durability and strength. Rounded profiles with a 2.5 mm radius, typical of the MB-SR50 system, have been replaced by “sharp edge” profiles in the MB-SR50N system. This change enhances the structure’s aesthetics. The new profile shape allows mullion and transom profiles to align flush on the interior façade surface. When glazed, the structure forms a truss-like appearance. It facilitates a visually pleasing and precise connection with internal walls and suspended ceilings.

Key Features:
- Aesthetic and Functional Design
- Offers narrow, visible division lines for an elegant appearance.
- Structural durability and strength ensure long-lasting performance.
- Updated “sharp edge” profiles replace the rounded profiles of the MB-SR50 system, enhancing the design’s modern appeal.
- Profile Innovation
- Mullion and transom profiles align flush on the interior surface, improving visual uniformity.
- The design allows for a seamless, truss-like appearance when glazed.
- Facilitates precise connections with building elements such as internal walls and suspended ceilings.
- Versatile Applications
- Suitable for suspended curtain walls, infill types, roofs, and skylights.
- Designed for compatibility with other architectural elements.
Benefits of the MB-SR50N System
- Enhanced Aesthetics: The “sharp edge” profiles create a sleek, contemporary look.
- Structural Integrity: Provides the durability and strength required for modern architectural demands.
- Improved Integration: Allows for a cohesive connection with other building components, ensuring precision and harmony.
- Innovative Profiles: Flush interior alignment enhances visual consistency across the façade.
The MB-SR50N façade system is a versatile and visually appealing solution for lightweight structures. Its innovative design ensures both aesthetic and structural excellence, making it an ideal choice for modern architectural projects.

The MB-SR50N system features a wide selection of mullion profiles (65 mm to 325 mm) and transom profiles (5 mm to 189.5 mm), along with modern solutions for accessories and connecting members. These features enable the system to handle a wider range of loads, with infill in a fixed module of the façade weighing up to 1100 kg. The system provides significant flexibility in arranging façade fixing points, and its wide glazing range supports large dimension glazing and two-chamber insulating glazing units.
The system allows for the installation of various window and door types in the façade, including awning and roof windows. The MB-SR50 IW solution achieves particularly good visual effects when façade-integrated windows are installed in this system.
To construct broken walls in vertical and horizontal sections, special overlapping profiles and properly shaped clamping and concealing strips are used, eliminating the need for special corner mullions and allowing for versatile building shapes.
Heavy-duty façade consoles are adapted to handle the maximum weights of the infills compatible with this system.
