GLR-63Insulated Bi-Fold System
Designed to open wide architectural spans through controlled folding movement, GLR-63 combines a top-hung mechanism, robust profiles and reliable insulation to create a flexible transition between interior and exterior spaces.
- 1 1/8″ × 2 3/8″ frame profile geometry
- 2 7/8″ × 2 3/8″ sash profile geometry
- Flexible multi-sash folding configurations
Flexible Living Across Wide Openings
Folding freedom, balanced movement and insulation performance in one system.
Wide Openings
The orderly stacking of multiple sashes allows a large portion of the architectural opening to remain accessible.
Durable Mechanical Structure
Transferring the sash load to the upper frame reduces stress on the threshold and limits wear over time.
Flexible Stacking Options
Multiple stacking arrangements support different opening widths, circulation needs and architectural layouts.
Heat and Sound Insulation
The insulated profile structure helps preserve indoor comfort across expansive glazed surfaces.

Explore the folding mechanismTop-Hung Bi-Fold Mechanism
By transferring the sash weight to bearings connected to the upper frame, the system reduces stress on the threshold. Precise alignment allows wide sashes to move smoothly, steadily and reliably, even under frequent use.
Load Transfer to the Frame
Transferring the sash load to the upper carrier system reduces pressure on the threshold and floor finish.
Balanced and Stable Movement
Controlled sash geometry reduces friction and vibration, improving comfort in everyday operation.
