Aluminium facades ALUPROF


The new, modern MB-TT50curtain wall system goes a step ahead in functionality and effectiveness compared to classic crossbar facades. It offers exceptional insulation and weather performance achieved by special 3 zone cascade drainage and ventilation of the glazing rebates. Its innovative construction enables to reasonably reduce the time required to manufacture and construct the complete curtain wall. It is designed to serve as the base system for security anti burglary and fire rated varieties.

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 system is a modification of a very popular MB-SR50 façade  system, meeting the demands of current trends in architecture.

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 450 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.



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.
