The MB-SR50N EI and MB-SR50N EI EFEKT mullion-transom curtain wall systems are engineered to construct lightweight, suspended, and in-filled fireproof curtain walls. These systems are classified with fire resistance ratings ranging from EI 30 to EI 60 and are suitable for both flat and angled walls. With the capability to form connections between modules at angles of up to ±7.5° and to create inclined curtain walls tilted by ±10°, these systems offer exceptional flexibility in design. Additionally, they support MB-78EI-based fire doors, seamlessly integrating door functionality into curtain wall assemblies. Both systems also serve as a foundation for fireproof glazed roofs with inclination angles ranging from 0° to 80° and fire resistance classifications of REI 30 / RE 45.

Key advantages

Fireresist.co fire protection systems provide consistent aesthetics, maintaining the same visual appearance for both fireproof and non-fire-rated elements within a curtain wall facade. They also offer diverse design options for capping, allowing for tailored aesthetics. The flexibility of the system accommodates facetted joints with angles up to ±7.5° per side, inclined facades with up to ±10° tilt, and roof glazing between 0° and 80°. Full compatibility with the MB-78EI system allows the integration of fireproof doors into curtain wall designs, enhancing both functionality and fire safety.
