The MB-SR50 EI curtain wall fire rated systems have been developed to provide a light-weight curtain & fire resistant wall, of classes EI 15, EI 30, EI45, EI 60 classes according to EN 1364-3 and EN 1364-1 and of fire-resistant glass-covered roofs. The system is classified as non-fire spreading (NRO).
These solutions use profiles of the basic, MB-SR50 and MB-SR50N facade systems: mullions of a depth of between 85 and 225 mm and transoms of a depth of 65 and 189.5 mm. Both systems are linked technologically and functionally, the main difference between them lies in the shape and depth of the profiles: rounded profiles with a radius of 2.5 mm characteristic of the MB-SR50 are replaced by the“sharp edge”in the MB-SR50N system. This affects substantially the aesthetics of the structure – the MB-SR50N system design is such that, like size transoms & mullions will provide a flush internal finish of the “box aspect” of the profiles, creating a desirable, unified grid appearance. This allows the glazing building to be a unified-looking grid. The design of the fire rated curtain wall system allows the use of angled connections to ± 7.5° per side, angled connections 90° or 135° (internal or external) and building façades tilted from the vertical at an angle of ± 15°. It is also possible to install the MB-78EI fire doors while maintaining the fire resistance of the whole structure in classes EI 30 or EI 60. |

MB-SR50 EI EFEKT system is designed for fabrication of fire-rated, EI15 - EI60 infill curtain walls. What distinguishes this product, is the external appearance of the facade, which is free from any visible aluminium elements. In its profiles, the mullion and transom support structure has a special core protected by fire-retardant inserts. It may be inclined from the vertical by an angle of ±15°.
