The mullion-transom curtain wall

Thanks to the rich offer of profiles, the architects and designers designing enginners may realize even the most bold concepts as regards the aluminium-glass structures.
 

The system is intended for constructing and creating the light-weight curtain walls of hanging and filling type, as well as roofs, skylights and other structures.
The shape of mullions and transoms allows building aesthetic facades with visible narrow dividing lines, ensuring the structure durability and resistance at the same time. Additionally, the profiles have rounded external edges, what gives the so-called soft-line effect.

The large number of mullions and transoms available in this system guarantees the best possible aluminium use. The economic profiles were obtained by optimization of the intersection shape and by selecting the optimal wall thickness. At a very high load, all mullions may be additionally reinforced with typical internal aluminium profiles, increasing their resistance. The simple profile processing lowers the workload and eliminates all types of carvings at the side surfaces of the mullions.

Application of the thermal break made of insulating material HPVC and the glazing gaskets made of EPDM allows achieving the appropriate class of thermal insulation.

Thanks to the sandwich structure of the lintel-window sill strip, in which the non-flammable materials such as mineral wool and plaster boards are used, the fire resistance classification was obtained depending on the construction of F0.25(EI15)NRO, F0.5(EI45)NRO.
For construction of the broken walls in horizontal and vertical section, the special overlay profiles as well as appropriately shaped clamping and cover beads are available, what eliminates the restrictions in shaping the building mass as well as the necessity to use special angular mullion. The accessories delivered with the system, aluminium supporting elements and connectors fixing the wall to the building surface are made of AlMgSi0.5F22 aluminium alloy.

In facades based on the MB-SR50 system, various shapes of cover beads can be applied. The aesthetic variation of this is the so-called horizontal and vertical line, where the horizontal or vertical divisions are emphasized. This system constitutes the base also for other solutions: “semi-structural” wall MB-SR50 EFEKT, the “Industrial” type of façade, structures applied with the overlay method on the supporting wood or steel framework (MB-SR50 A). In all those variants, apart from standard opening elements, it is possible to use skylight windows and tilt windows, basing on the structural wall system MB-SG50.

Façade systems - General information

Our façade systems are used to fabricate glass façades of buildings such as banks, hotels, administration offices, office buildings, car showrooms, gyms, etc. They are also used for multiple spatial structures and roof glazing that light the interior and create a suitable atmosphere and comfort to its users. They are an excellent tool for shaping contemporary architecture and implementing designers’ bold visions. The most popular among these products are the mullion-transom systems. ALUPROF’s façade solutions include also a range of products of various design and appearance, including a bunch of individual solutions.

The MB-TT50 mullion and transom façade is the company’s most state-of the art solution. This product brings a whole new approach to the construction of profiles and accessories for tightness and thermal insulation. What’s more, the installation technique has changed as well. This allows us to offer a product with one of the highest performances among aluminium façade systems available on the market, ideally suited to the needs of energy-efficient and passive buildings.

An important place in our façade systems is occupied by the mullion-transom wall MB MB-SR50N. It has enhanced thermal insulation variants: MB-SR50N HI and MB-SR50N HI+, as well as variants for fabricating constructions of different appearances: vertical or horizontal line or “semi-structural” façade MB-SR50N EFEKT. When it comes to openable elements, the MB-SR50N is the basis for constructions such as tilt-and-pull windows MB-SR50N OW, façade-integrated windows MB-SR50N IW, and, very aesthetic and functional roof windows MB-SR50N RW. The MB-SR50N mullion-transom system is also a basis for fire resisting façades MB-SR50N EI and glazed roofs. The MB-SR50N-based roof constructions and façades can optionally be fabricated in a fire-resistant variant.

ALUPROF façade offering also includes structural glazing systems: MB-SG50 and the semi-structural MB-SG50 SEMI designed to fabricate façades that convey to the buildings a prestigious appearance and a representative character.

In top of the façade systems we offer EXTRABOND ventilated wall whose external coat consists of wall cladding. It ensures a very good appearance and an excellent thermal insulation of the construction.
A separate group of façade systems are segment-based walls, such as MB-SE75 and individual solutions,  that is, systems designed with respect to strict criteria set out in collaboration with buildings’ designers. These systems are, by definition, designed to meet project-specific requirements for aesthetics and performance.
