MB-79N WW Window Wall System – Designed to Meet American Demands

The MB-79N family of solutions has been expanded with a new addition to Aluprof's extensive portfolio. The MB-79N WW Window Wall System has been specifically developed with the American market in mind, where window walls are a highly popular architectural feature.

Window wall systems are typically installed between concrete floor slabs in medium- to high-rise buildings. This new solution from Aluprof allows for the creation of expansive glazed façades using prefabricated window wall segments. It is particularly striking when installed floor-to-ceiling, delivering an impressive effect with large transparent surfaces.

This new addition to Aluprof’s portfolio is a complete and versatile system, built on proven solutions from the popular MB-79N family, including profiles and thermal breaks. A key feature of the system is the upper frame, which compensates for deflections in concrete slabs of up to +/-25.6 mm (approximately 1 inch in US customary units). Starter profiles are available in depths ranging from 83 to 307 mm.

Window walls constructed using the MB-79N WW system can include fixed windows, inward- and outward-opening balcony/patio doors, as well as standard or expansion mullions. One of the most notable advantages of this system is its reduced assembly time and the minimal number of workers required for installation. The process can be broken down into stages: first, the starter and expansion profiles are installed, followed by the windows, which are mounted using specially designed clips. Furthermore, the system is installed entirely from within the building, ensuring efficiency and safety during assembly.

The first projects featuring the MB-79N WW system include residential buildings at 210 Clarkson Avenue and 2840 Atlantic Avenue in Brooklyn, New York, as well as the 625 Fulton Street multifunctional tower. This 35-storey skyscraper rises over 500 feet (150+ metres) tall and serves as a mixed-use development in the heart of Brooklyn.
