MB-Skyline Type S – Premium Slim Sliding Door System
The Bertrand MB-Skyline Type S system represents a new standard in minimalist architectural glazing. With ultra-slim aluminum profiles fully integrated into surrounding walls and ceilings, it delivers a clean, frameless aesthetic and a seamless connection between indoor and outdoor spaces. The exceptionally narrow 25 mm mullion at the meeting point of door leaves enhances the sense of lightness and transparency, making the system a perfect choice for luxury residences, modern villas, and high-end commercial projects.
Minimalist design and seamless integration
The MB-Skyline Type S takes architectural glazing to the next level. The system features a fully concealed gap threshold, allowing completely smooth transitions between interior and exterior spaces.
Its bottom profile and sliding mechanism are hidden within the floor structure, leaving only a slim, elegant line visible. Building on the success of the MB-Skyline family, this version delivers refined engineering, exceptional craftsmanship, and effortless operation even for large, heavy door panels.
