Technical description:
MB-SR50N – Post and beam wall
The system is designed for the construction and execution of light curtain walls - flat, suspended and filled as well as roofs, skylights and other structures. This solution is a modification of a very popular facade system MB-SR50, which faces the current trends in architecture.
The shape of posts and beams enables construction of aesthetic facades with visible narrow dividing lines, while ensuring the durability and strength of the structure at the same time. One of the characteristic features of the MB-SR50 system which is the 2.5 mm radius rounding of the sections has been replaced with a so called sharp edge in the MB-SR50N system. This treatment fundamentally influences the aesthetics of the structure - the applied profile shapes make it possible to choose profiles of posts and beams, which gives the effect of facing the surface of the posts and beams from the inside of the façade. Thanks to this, the glazing can form a uniform lattice. At the same time it facilitates aesthetic and accurate connections with other elements of the building: internal walls and suspended ceilings.
The most characteristic features of the MB-SR50N system also include a wide range of post profiles (from 65 mm to 325 mm) and beams (from 5 mm to 189.5 mm) and modern accessories and connectors. They allow for increased load carrying capacity - the filling of the fixed facade module can weigh up to 450 kg. The MB-SR50N system offers considerable freedom in the design of façade fastening points, a wide range of glazing also allows the use of large-sized glass and multiple-glazed double-chamber units.
The use of continuous thermal insulation made of insulating HPVC material and profiled EPDM glazing gaskets makes it possible to achieve the appropriate class of thermal insulation and minimizes the condensation of steam on aluminum components.
PL versions (horizontal and vertical lines, where horizontal or vertical divisions are underlined) and a semi-structured facade of the EFEKT type constitute one of the MB-SR50N's aesthetic variants, similarly to the previously known post-beam facades. Especially noteworthy is the MB-SR50N HI version with increased thermal insulation index which uses special two-component insulators.
The MB-SR50N system enables integration of different types of windows and doors including windows dedicated to facades: hinged windows and roof windows into the façade. Particularly impressive is the use of windows integrated in the façade, based on the MB-SR50 IW solution.
The spandrel of the façade thanks to its layered construction made with the application of non-flammable materials such as mineral wool and gypsum plasterboard can, similarly to other Aluprof facade systems, obtain fire classification according to EI30 and EI60 construction.
For preparation of horizontal and vertical section broken-line walls special overlay profiles and appropriately shaped pressure and masking strips are predicted, there is no limit to the shape of the building and the need for special angular posts is eliminated.
The reference document for declaration of conformity for vertical façades based on the MB-SR50N system is the Harmonized European Standard ‘PN-EN 13830 Curtain walls - product standard’
On the basis of this system you can also make burglar-proof structures.
