A U-shaped glass partition divides a space from floor to ceiling using only horizontal top and bottom frames, without additional vertical or horizontal supports. A single glass panel can reach 10 meters. This tall glass partition system provides a clean appearance without vertical or horizontal reinforcement. In addition to dividing spaces, it offers advantages over traditional glass partitions in daylighting, sound insulation, fire protection, environmental performance, ease of installation and reuse. By glass type, the options include single-layer, double-layer, laminated and prefabricated hollow U-glass partitions. By function and properties, they include tempered, fire-resistant, ultra-clear, laminated explosion-resistant and artistic U-glass partitions.
