GLIDE21 - The exclusive next-generation frameless aluminium sliding door system that is designed to disappear.

GLIDE21 is a minimalist sliding door system designed to disappear into the architecture. With fully concealable frames that can be integrated into the surrounding structure, the system leaves only clean 21mm sightlines visible, creating a seamless connection between inside and out.

Design, Aesthetics & Configuration

GLIDE21 is engineered for absolute clarity and openness, featuring a slim 21 mm interlock . The fully concealed outer frame and hidden sash create the impression of a continuous frameless glass wall — perfect for modern architecture and premium refurbishments.

With multiple reinforced interlock options and flexible panel configurations, GLIDE21 provides both design freedom and architectural precision.
