Over 90 standard configurations for straight-forward folding systems.
Standard configurations show the most common way folding glass wall panels align across a straight opening. Panels operate in a continuous line without special conditions such as corner openings, wall pockets, or intersections, making this layout a clear starting point for planning straightforward openings.

Window-door combination configurations integrate folding windows and folding glass doors within the same opening or wall plane, enabling independent control of daylight, ventilation, and entry. Commonly used for indoor/outdoor kitchens, this layout supports flexible layout design and a clean, consistent visual flow across the space.

Segmented configurations arrange operable glass wall panels across multiple angled or curved segments, allowing the system to follow architectural geometry beyond a straight line. This layout supports faceted walls, gentle curves, and radius designs while maintaining operability and visual continuity across residential and commercial applications.
View More Segmented Configurations View Product Applications
Cornerless (Open Corner) configurations remove the vertical corner post where two operable glass walls meet at 90°, allowing panels to open in multiple directions and create a fully unobstructed corner opening. This layout enhances visual openness, spatial flow, and flexible indoor-outdoor transitions.
All standard configurations are available in cornerless options.
