GLR-64Insulated Bi-Fold System
Designed to open wide architectural spans through controlled folding movement, GLR-64 combines a bottom-running carrier mechanism, high sash capacity and insulated profiles to create a robust and reliable transition.
- 29 × 86 mm frame profile geometry
- 76 × 76 mm 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
The bearing connected to the lower frame supports the sash weight evenly and contributes to stable system operation.
Flexible Stacking Options
The sash can collect at 45° and the frame at 90°, supporting different architectural use scenarios.
Heat and Sound Insulation
The insulated profile structure helps preserve indoor comfort across expansive glazed surfaces.

Explore the folding mechanismBottom-Running Bi-Fold Mechanism
The system carries the sash weight through a bearing connected to the lower frame, transferring the load evenly to the floor. Integrated horizontal guide bearings limit unwanted rotation and preserve precise sash alignment and secure folding movement.
Lower Carrier Bearings
Carrying the sash weight through the bearing connected to the lower frame ensures balanced and reliable movement across wide sashes.
Horizontal Guide Bearings
The guides limit unwanted rotation of the upper bearings and maintain precise alignment throughout operation.
