Fire Rated Curtain Wall

The MB-SR50 EI and 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 PN-EN 1364-3 and PN-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.

Fire Rated Aluminium Facade

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°.

Fire Rated Glazed Roofs

Based on the MB-SR50 EI and MB-SR50N EI facade systems, it is possible to perform roof glazing with fire resistance class RE20, RE30, REI20, REI30 according to PN-EN 13501-2 + A1: 2010.
Regular curtain wall mullions & transoms are used as roof glazing rafters & purlins, suitably joined to each other to form an aluminium grid structure, which is in turn mounted to the building structure by means of appropriate supports. Similar to the vertical curtain wall offer, these rafter & purlin profiles are fitted with fire resistant inserts, consisting of an aluminium insert profile acting as reinforcement, and surface clad with fire-proof board. The standard solution does not require any additional support such as steel.
Fire tests performed on two versions: at and inclined, have assured classification of roofs with an inclination of 0° to 80° from the horizontal level. Rafters with a depth of 85 + 225 mm and purlins with a depth of 65 + 189.5 mm may be used in this structure. Window inserts are installed into the glazing rebate of the rafter & purlin formed grid, & fixed securely by the pressure plate clamping strip, screw fixed back to the carrier profiles. Within this system, it is possible to apply glazing thicknesses ranging from 36 to 52 mm. The maximum dimensions of the glass are 2100 mm x 1100 mm, however, changing these dimensions is acceptable, providing there is no exceeding of the maximum surface area of the glass. Fire resistant glass can be used in a composite set with any glass placed in the system on the outside. Glazed fire resistant roofs can be combined with the MB-SR50 EI and EI MB-SR50N vertical facades.
