European MB-77HS lift-and-slide aluminum system

What is Aluprof MB-77HS system?

The MB-77HS is a high-performance lift & slide system designed to combine effortless movement with excellent thermal insulation. It allows large glass surfaces and seamless indoor-outdoor transitions, making it ideal for contemporary residential and commercial architecture.
Lift & slide mechanism lifts the sash from the frame when opening, allowing the door to slide smoothly along the track with minimal effort. When closed, the sash lowers into a tight seal for improved insulation and secure locking.
MB-77HS uses thermal breaks, high-performance seals, and multi-point locking to reduce heat transfer and air infiltration. This supports better indoor comfort and contributes to lower energy consumption — especially important in climates with temperature extremes.
The system supports a wide variety of configurations, including large panels, multiple tracks, and fixed elements, allowing designers to create expansive glazed facades while maintaining aesthetics and performance.
MB-77HS encourages minimal sightlines and maximized transparent surfaces, aligning with contemporary design trends that emphasize light, openness, and seamless indoor-outdoor integration.
