Certificates:

MB-SR50N HI is a modern aluminium curtain wall system based on a mullion-transom structure, designed for buildings where energy efficiency is a top priority. Thanks to the use of advanced two-component thermal breaks, it enables the creation of elegant glazed façades while maintaining excellent thermal performance.

With a Uf value of 0.85 W/(m²K), MB-SR50N HI ranks among the leading energy-efficient façade solutions. The system was created for projects in which operating costs—especially heating and air conditioning—play a crucial role in the long-term management of a building.

Intelligent façade design for modern construction

MB-SR50N HI fully meets the challenges of contemporary architecture – both in terms of design and fabrication. The system’s proven HPVC insulators, combined with LDPE material featuring enhanced thermal insulation, not only improve the façade’s performance but also make the installation process significantly easier. Their structure allows precise screw guidance and shortens installation time on site.

The MB-SR50N HI façade offers outstanding design flexibility. It enables the use of large glazing panels, opening new creative possibilities for architects in shaping the building’s form and emphasising its modern character. MB-SR50N HI performs perfectly in office buildings, airport terminals, railway stations and other prestigious developments where aesthetics must go hand in hand with superior insulation.

The system can also be seamlessly combined with high-insulation window and door systems such as MB-79N, MB-86N and MB-104 Passive, maintaining a uniform energy standard across the entire building. It also accommodates opening elements designed for mullion-transom façades, such as MB-SR50N OW tilt-and-slide windows and MB-RW roof windows.

Energy-efficient construction in practice

In times of rapidly rising energy costs and increasingly strict energy-efficiency regulations, the choice of a façade system has a major impact on a building’s overall performance. MB-SR50N HI embodies the principles of low-emission construction, offering a durable, aesthetic and functional solution – without compromise. A version with even higher insulation, MB-SR50N HI+, is certified by the Passive House Institute (PHI) in Darmstadt.
