Aluprof SR-50N HI

The MB-SR50N HI system features basic characteristics and possibilities inherent in the base construction MB-SR50N. The thermal insulation zone deserves a particular mention, though. Here, special two-component insulators have been applied. They are based on a HPVC insulator (or a set of insulators of appropriate width), which makes it possible to drive screws with high accuracy during the installation process at the building site. On both lateral surfaces of the insulator additional elements made of flexible material are attached (glued on), which enhance thermal insulation performance and limit the air flow in the space separating the infills of the façade. The insulator built in this way enables maintaining convenience and accuracy of mounting of a traditional façade, ensuring at the same time that very good thermal insulation parameters are attained – the heat transfer coefficient, depending on the applied profiles and accessories spans between 0,94 to ,.94 W/m2K. Likewise in the base version of the façade, the structure allows for installation of different types of infills, including glazing of large dimensions and two-chamber insulating glazing units. With regard to active elements, the MB-70HI doors and windows featuring enhanced thermal insulation performance are particularly recommended for façades of the HI series.

SR-50N HI - key benefits:

  • Aestetic curtain wall varieties and a number of lining profiles of various shapes providing multiple curtain wall appearances
  • Angle joints enabling the free shaping of aluminium structures
  • A large choice of curtain wall opening elements: windows and doors of various types, including skylight windows and windows integrated with the curtain wall, as well as tilt and parallel opening MB-SR50N OW windows



The MB-SR50N HI system was subjected to thorough testing performed by the Building Research and Testing Institute IFT Rosenheim and attained very high technical parameters.


  • Air infiltration: class AE 1200, EN 12152
  • Rainwater tightness: class RE1500, EN 12154
  • Resistance to wind load: 2.4 kN/m2, EN 13116:2002
  • Impact resistance: class I5/E5, PN-EN 14019

As regards the declaration of conformity for vertical façades based on the MB-SR50N HI system, a harmonized European Standard PN-EN 13830 “Curtain Walling. Product Standard” has been applied as a reference document.


The structure presented here is a version of MB-SR50N featuring enhanced thermal insulation performance.


The system is designed for the construction and execution of flat, light-weight curtain walls of the suspended or filling type, roofs, skylights and other structures. The shapes of profiles enable selection of mullion and transom profiles which flush with each other on the inside surface of the façade.
