Segment-based façade - MB-SE75
This segment-based curtain walling system is intended for execution of individual facilities, in case of which time-efficiency of the assembly and elimination of external scaffolding during the erection are among basic requirements.
The construction of the MB-SE75 façade comprises segments mounted to the bearing construction of the building, joined with each other. The process of prefabrication of elements takes place in a production plant, which significantly enhances the quality of the final product. The technological concept adopted in this case results in a number of fundamental benefits of this solution: the assembly time at the building site is significantly shorter compared to a traditional mullion – transom façades, due to the application of complete glazed segments; the costs of erection are also reduced due to the total elimination of external scaffolding.
The system of segment-based façade also meets the strictest technical and aesthetic requirements. The development performed in this system features visible profiles of the width of 75 mm with a narrow 9 mm expansion gap between individual segments.
Depending on resistance requirements, the system includes an array of profiles of the depth of 85-145 mm. The thickness of the infills in the MB-SE75 façade ranges between 26 and 42 mm. The system features very good thermal insulation performance. The overall heat transfer coefficient Uf for mullions and transom, depending on their function comes within the range from 1.56 to 2,83 [W/m2K].
The construction features high resistance to water and air infiltration, supported by the parameters achieved during the test performed by the Building Research Institute.
- air permeability: class AE1200 PN-EN 12152:2004
- water tightness: class RE1200 PN-EN 12154:2004
- resistance to wind load.
- design wind load 2400[Pa] PN-EN13116:2004
- safety wind load 3600[Pa] PN-EN13116:2004
- impact resistance: class I5/E5 PN-EN14019:2004
Initial Product Type Test ITT [Building Research Institute] was carried out according to the product standard PN-EN 13830:2005.
A wide variety of opening elements can be installed in the façades of the MB-SE75 system: door and windows based on the MB-70 or MB-70HI systems, windows with a hidden sash MB-70US, MB-70US HI or as MB-70SG, as well as “frame-free” constructions opening outward, based on the structural system MB-SG50.
Flexible compatibility of particular elements of the system allows to optimally adjust the construction to specific requirements of a particular facility.
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.
