  • MB-SR50N HI+ energy-efficient curtain wall – what makes it different?

    The MB-SR50N HI+ mullion-transom wall meets the most stringent requirements relating to quality and safety, as confirmed by the A+ certificate issued by the Passive House Institute (PHI) in Darmstadt. This means that the curtain wall is energy-efficient (thermal insulation from 0.59 W/m2K) and suitable for the construction of passive buildings, which are friendly to the environment and your wallet.

    This particular curtain wall can be supplied with three glazing options, including double- and triple-chamber glazing, to achieve even better technical specifications. The mullion-transom wall also conforms to the requirements of the EI 30 and EI 60 fire resistance classes. This important feature is the reason why MB-SR50N HI+ is an attractive solution also for people interested in enhanced fire safety. 

    Energy-efficient mullion-transom wall from Aluprof

    Our offering includes a wide range of modern hardware, accessories and openable parts, such as windows and doors, including tilt and parallel opening windows or sloped windows integrated with the curtain wall. This way, you can design your façade as you please, adapting it to your individual needs and preferences. Choose the MB-SR50N HI+ energy-efficient curtain wall and make your home both beautiful and functional!

    The MB-SR50N HI+ mullion and transom façade system has been designed to construct lightweight curtain walls of a hanging and filling type as well as roofs, skylights and other spatial constructions.

    This system allows façades to be constructed with visible narrow dividing lines while ensuring the durability and strength of the structure. The wide offer of profiles enables the architects and designers to realise even the most enterprising ideas for aluminium and glass structures. To obtain the optimum thermal and acoustic insulation and facilitate mounting in the MB-SR50N HI+ system façade, the PE insulator was used, as it provides a very good thermal insulation ((Uf) from 0,59 W/m2K) and its shape ensures proper screw driving when glazing the façade.

    As regards the opening elements in “HI”-type façades with improved thermal insulation, the use of windows and doors with improved thermal insulation in MB-86 Aero system is especially recommended.

    Features that affect the functionality and aesthetics of MB-SR50N HI+ façades:

    • mullions and transoms with “sharp” edges allowing the construction of a curtain wall supporting structures with the appearance of a uniform truss
    • angle joints enabling the free shaping of aluminium structures
    • aesthetic curtain wall varieties and a number of lining profiles of various shapes providing multiple curtain wall appearances
    • a large choice of curtain wall opening elements: windows and doors of various types, including skylight windows and windows integrated with the curtain wall, as well as tilt and parallel opening MB-SR50N OW windows
    • a wide glazing range (also two- and three-chamber) with the availability of insulators and accessories allowing a high level of curtain wall thermal insulation
    • heavy-duty façade consoles, adapted to the maximum weights of the infills that can be used with this system

    Technical parameters of the system:

    • Air permeability: AE (1050 Pa), EN 12153:2004; EN 12152:2004
    • Watertightness: RE 1200 Pa, EN 12155:2004; EN 12154:2004
    • Wind load resistance: 2400 Pa, EN 12179:2004, EN 13116:2004
    • Impact resistance: I5/E5, EN 14019
    • Fire resistance: may be produced in EI 30 and EI 60 version
    • Thermal insulation Uf: from 0,59 W/m2K
