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 0.7 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
