The KS51.1 SL ES [Opulenz] supports configurations of up to 6 panels, each up to 2.0 m (w) × 4.0 m (h) -enabling vast, uninterrupted glazed facades that blur the boundary between interior and exterior in the most ambitious architectural projects.

A 90° corner opening provision eliminates the need for structural corner posts, delivering a truly frameless corner experience and granting architects and designers complete freedom to create panoramic, light-filled spaces without visual interruption.

The slim 22–25 mm interlock width sustains refined sightlines even at maximum panel scale, while the system’s compatibility with SG, DGU, and laminated DGU glazing from 8 to 36 mm ensures it meets every thermal, acoustic, and safety performance requirement a premium project demands.

CRAFTED FOR PERFORMANCE 

System Features

The KS51.1 SL ES [Opulenz] is a robustly engineered, highly stable sliding system rated for a wind load of up to 3 kPa – making it one of the highest-performing slim interlock systems available for exposed, high-rise, and climatically demanding environments.

Specially designed heavy-duty rollers bear panel loads of up to 400 kg per panel, ensuring that even the most expansive glazed panels glide with consistent, effortless precision throughout the lifetime of the installation.

A comprehensive multiple locking system secures every panel configuration to the highest security standard, while the 90° corner opening provision and broad glazing compatibility from 8 to 36 mm cement the KS51.1 SL ES [Opulenz] as the definitive sliding system for luxury residential and prestige commercial projects.
