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 U
f 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.

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.
