Windows are a fundamental component of modern architecture. They serve as the connection between the interior and the exterior of a building, significantly contributing to the façade’s visual appeal. Beyond contemporary design, windows must also ensure excellent insulation qualities and ease of operation. When seeking innovative solutions that combine aesthetic appeal, functionality, and environmental friendliness, aluminum systems are a highly recommended choice. They provide all these features and offer extensive versatility in adapting window designs to meet the specific needs of the building and its occupants.


Aluminium windows that complement architectural style
The wide selection of aluminium windows offers numerous design options. The primary factor in choosing the right type is the opening method, which should be tailored to the building’s character and the functionality of the room where the window is to be installed.
Modern aluminium window variants include: outward tilt/turn (e.g., MB-86 CASEMENT, MB-59S CASEMENT, MB-59S CASEMENT HI); sliding (e.g., MB-SKYLINE TYPE R, MB SLIDE, MB SLIDE ST, MB SLIDER WINDOW); and pivot (e.g., MB-60 PIVOT, MB-59S PIVOT, MB-59S PIVOT HI). This extensive range allows for choosing the perfect solution even for the most demanding projects. Selecting the appropriate opening system is crucial not only for ease of use but also considering the window area and size. This variety enables the fitting of even small rooms with aesthetically pleasing and well-insulated windows.
ALUPROF aluminium systems – combining functionality with aesthetics
A vital consideration when choosing windows is their appearance and alignment with the architectural style. The design of the window, such as the use of concealed sash or narrow profiles, plays a significant role. Some systems (e.g., MB-45) even allow profile bending—frames, sashes, or battens—making it possible to adapt to architectural arches.
Aluminium joinery with a concealed frame, such as MB-60 US, MB-60 US HI, MB-70 US, or MB-70 US HI, is ideal for buildings requiring wall-to-wall windows with hidden sashes outside. Narrow window frames create an impression of sleek, lightweight architecture.
Systems like MB-FERROLINE and MB-SLIMLINE, resembling traditional steel joinery, are designed for properties needing very slim profiles, making them especially suitable for historic renovations. These systems not only provide a characteristic aesthetic but also offer excellent thermal insulation (Uw from 0.8 W/(m2K)) and water tightness (Class E1350 EN 12208).
For an industrial look, aluminium options such as MB-FERROLINE or MB-60HI emphasize raw, minimalist aesthetics while maintaining high insulation standards; for example, the Uf coefficient in the MB-60HI system is 1.48 W/(m2K).

Aluminium joinery can also be used as external balustrades. The MB-GLASS BARRIER system is suitable for porte-fenêtre windows and Juliet balconies, offering protection against falls and sound insulation.
Energy-efficient and passive windows
Modern construction standards emphasize excellent insulation. Aluminium windows are available in energy-efficient and passive variants.
Energy-saving systems (e.g., MB-86 N, MB-79N, MB-79N US) feature additional dividers to ensure high thermal insulation (Uw from 0.62 W/(m2K)) and low frame heat transfer.
For passive buildings, the MB-104 PASSIVE system boasts the highest thermal insulation, with ratings confirmed by the Passive House Institute in Darmstadt. Its Uw for an opening window is from 0.53 W/(m2K). The system sections are available in variants such as SI and AERO, depending on energy efficiency needs.
Interior aluminium solutions
Aluminium is also used for internal structures, such as glazed partition walls in offices and public buildings. Systems like MB-HARMONY OFFICE, MB-80 OFFICE, MB-45 OFFICE, and MB-EXPO (noted for the highest thermal insulation within this group) can be configured as fixed or operational internal walls, providing high acoustic insulation (Rw 48 dB/Ra1 46 dB).
Fire-resistant aluminium windows
Aluminium joinery is available with high fire protection performance, featuring toughened fire-retardant glass and insulation elements (e.g., MB-86EI, MB-60E EI, MB-78EI). These meet EI30, EI60, and EI15 resistance classes, allowing for stylish, glazed structures up to 3.6 meters high.
Fire-protection solutions also include windows and smoke ventilation dampers based on systems like MB-59S and MB-86 US, equipped with silent opening mechanisms for effective fire safety.
Aluminium windows for sustainable construction
Aluminium windows not only feature a modern design but also offer practicality and durability. Combined with high insulation values and eco-friendly manufacturing, they align with sustainable building principles. Choosing aluminium creates long-lasting, energy-efficient windows ideal for today’s demanding construction standards.
