The KS42.1 SL ES [Majestic] supports up to 6 panels with a maximum individual panel size of 1.5 m (w) × 3.0 m (h), enabling expansive, light-filled openings for contemporary living spaces, hotel lobbies, and commercial facades of the highest specification.

Two-track and three-track frame configurations with a stainless steel guiderail and inside lip provision give project teams full flexibility to adapt the system to varying opening widths, design briefs, and site-specific requirements – with an optional integrated flyscreen for added comfort and functionality.

The 33 mm sleek interlock width maintains clean, uninterrupted sightlines across all panel counts, while the system’s compatibility with SG, DGU, and laminated DGU glazing from 5 to 32 mm ensures it meets the full range of thermal, acoustic, and safety glazing specifications demanded by today’s premium projects.

CRAFTED FOR PERFORMANCE 

System Features

The KS42.1 SL ES [Majestic] is a robustly engineered sliding system with a wind load resistance of up to 2.75 kPa, making it well-suited to exposed façades, elevated floors, and climatically demanding project environments across the region.

High-performance rollers capable of bearing up to 300 kg per panel guarantee smooth, consistent operation across the full range of panel sizes, ensuring the system performs as effortlessly in daily use as it does at first installation.

The stainless steel guiderail, inside lip detail, and optional flyscreen provision are fully integrated into the system architecture, while a comprehensive multiple locking mechanism delivers the elevated security standard expected in high-value residential and commercial installations.
