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 shape of mullions and transoms allows for erecting aesthetic façades with visible narrow division lines, ensuring at the same time durability and strength of the structure. Rounded profiles of the radius of 2.5 mm, characteristic of the MB-SR50 system, have been replaced in the MB-SR50N system by “sharp edge”. This change essentially influences the aesthetic aspect of the structure. The applied shape of profiles enables selection of mullion and transom profiles which flush with each other on the inside surface of the façade. When the structure is glazed, visually it forms a truss. It facilitates at the same time aesthetic and very accurate connection with other elements of the development - with internal walls and suspended ceilings.

Among characteristics of the MB-SR50N system is a wide choice of mullion profiles (between 65 mm and 325 mm) and transom profiles (between 5 mm and 189.5 mm) and modern solutions designed for accessories and connecting members. Such features allow for a wider range of loads which are being carried – an infill in a fixed module of the façade may weigh up to 1100 kg. The MB-SR50N system gives considerable freedom while laying out façade fixing points. A wide glazing range allows for application of glazing of large dimensions and two-chamber insulating glazing units.

Application of a continuous thermal barrier made of insulating material called ”HPVC” and profiled (grooved) EPDM glazing gaskets makes it possible to obtain proper thermal insulation class and reduce to a minimum vapour condensation on aluminium elements.

Among aesthetic varieties of the MB-SR50N system, likewise in older mullion / transom curtain walls are the following versions: PL (so-called “horizontal and vertical line” where an emphasis is placed on either horizontal or vertical division) and a semi-structural façade of the EFEKT type. A particular attention should be drawn to the version featuring enhanced thermal insulation performance, i.e. MB-SR50N HI, in which special two-component insulators have been applied.

The MB-SR50N system enables installation in the façade of various types of windows and doors, including windows designed for the façades incorporating an awning window and a roof window. A particularly good visual effect is achieved when façade-integrated windows based on the MB-SR50 IW solution are installed in this system.

Lintel and sill belts of the façade, due to a sandwich-type structure in which non–flammable materials have been used, such as mineral wool and plasterboards, may obtain, like in the case of other Aluprof systems, fireproof classification EI30 and EI60, depending on the structure.

In order to construct broken walls, both in their vertical and horizontal sections, there have been used special overlapping profiles and properly shaped clamping and concealing strips with the effect that there are no limitations whatsoever as to shaping the building body and the need to use special corner mullions is eliminated.

Heavy-duty façade consoles, adapted to the maximum weights of the infills that can be used with this system.

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