The MB-SR50N El curtain wall fire rated systems have been developed to provide a light-weight curtain & fire resistant wall, of classes E130, E160 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-SR50N facade system: mullions of a depth of between 85 and 225 mm and transoms of a depth of 65 and 189,5 mm. The MB-SR50N system allows for selecting mullion & transom profiles which provide a flush internal finish of the facade, creating a desirable, unified grid appearance. It is also possible to install the MB-78EI fire doors while maintaining the fire resistance of the whole structure in class El 60.
