GLR-U27Minimal Sliding System
Slim aluminum profiles, expansive glass surfaces and smooth operation come together in a refined sliding system designed around light, landscape and architectural continuity.
- Two-track and three-track frame alternatives
- Integrated project-specific drainage depths
- Minimal sightlines and uninterrupted panoramic views


Architecture stays in the background.
A minimal system language that brings daylight, views and spatial continuity forward.
Minimal Sliding Design
Slim aluminum profiles reduce visual interruption and allow the glazed surface to define the opening.
Smooth, Quiet Movement

Explore the minimal system detailsDesigned around the view.
GLR-U27 reduces visible profile mass so glass, daylight and the surrounding architecture remain at the center of the composition. Concealed frame details and a low sill create a more continuous transition between spaces.


Reduced Visual Mass
The upper frame geometry keeps technical components in the background and supports uninterrupted glazing lines.

Controlled Drainage
Project-specific drainage depths manage water discharge while maintaining a clean and considered threshold detail.
