The MB-SR50N EI and MB-SR50N EI EFEKT systems are advanced curtain wall solutions designed to create fire-resistant facades with classifications of EI30 to EI60. These systems form fire-safe zones within buildings, aiding evacuation while maintaining the look of non-fire-rated walls. Compatible with MB-78EI fire doors, they support flat, faceted, and inclined walls and roofs, making them a versatile choice for complex architectural designs.
Key Performance Specifications:
• Airtightness: Class AE 1050 Pa (PN-EN 12152)
• Watertightness: Class RE1200 (PN-EN 12154)
• Thermal Insulation: Uf ≥ 1.8 W/(m²K)
• Fire Resistance: EI30 and EI60 (EN 13501-2)
Features and Benefits:
• Seamless Design Consistency: Maintains uniform appearance for fire-rated and non-fire-rated sections of the curtain wall.
• Flexible Configuration: Supports angled joints up to ±7.5° per side, inclined façades up to ±10°, and roof glazing between 0° to 80°, enabling diverse architectural applications.
• Compatibility with Fire Doors: Designed to integrate with MB-78EI fire-rated doors within the curtain wall system.
• Roof Glazing Options: Fire-rated roof solutions (REI 30 / RE 45) can be incorporated for slope angles up to 80°.
The MB-SR50N EI and EFEKT versions allow architects to create safe, fire-resistant structures without compromising aesthetics or design flexibility, ideal for modern commercial buildings requiring advanced fire safety integration.
