MB-SR50N ZS: Mullion-Transom Curtain Wall with Integrated Façade Blind System

The MB-SR50N ZS is a modern mullion-transom curtain wall system designed for lightweight, suspended, or infill façades, as well as roofs and skylights. This system focuses on both high performance and sleek aesthetics, offering advanced thermal insulation and versatile design possibilities.

Key Features:

- Design Flexibility: Supports a wide selection of mullion profiles (65–325 mm) and transom profiles (5–189.5 mm), allowing significant load capacity (up to 450 kg per infill) and the use of large, two-chamber insulating glass units. The profiles are designed for a seamless interior flush look, forming a truss-like visual when glazed.

- Distinctive Aesthetics: Features a "sharp edge" profile design for a clean, modern appearance. Variants include horizontal/vertical line emphasis (PL version) and the semi-structural EFEKT façade. The MB-SR50N HI version enhances thermal performance with advanced two-component insulators.

- Thermal & Structural Performance: The system achieves a Uf value as low as 0.7 W/(m²K) through continuous HPVC thermal barriers and profiled EPDM glazing gaskets. It also ensures minimal vapor condensation on aluminum components.

- High Resistance: Demonstrates strong air infiltration resistance (AE 1200, EN 12152), watertightness (RE 1200, EN 12154), and wind load resistance (2.4 kN/m², EN 13116).

- Integration Capabilities: Accommodates various window and door types, including awning and roof windows, with seamless façade integration using MB-SR50 IW solutions. Fireproof classifications EI30 and EI60 can be achieved for lintel and sill belts using a sandwich structure with non-flammable materials.

- Architectural Adaptability: Special overlapping profiles and clamping strips facilitate the construction of broken walls, eliminating the need for corner mullions and supporting flexible building designs.

This system is an ideal choice for architects seeking high thermal efficiency, durability, and creative freedom in curtain wall designs, meeting the standards of EN 13830 for product conformity.
