U glass (also called U-shepe qlass. U channel glass, U profile glass, C glass) is a specialty architectural glass for interior and exterior wall applications, distinguishable by its signature linear aesthetic.

The U-shape glass channels are self-supporting, standing as tall as eight meters in a relatively lightweight 7mm or 8mm thickness. They require minimal perimeter framing, creating virtually seamless glass walls that can be hundreds of feet long and can span across elevations.

Advantages:

1. Daylighting: Diffuses light & minimizes glare, provides natural light without the loss of privacy.

2. Great Spans: Glass walls of limitless distances horizontally & heights up to eight meters

3. Elegance: Glass-to-glass corners & serpentine curves provide soft, even light distribution

4. Versatility: From facades to interior partitions to lighting

5. Thermal Performance: U-Value range = 0.49 to 0.19(minimal heat transfer)

6. Acoustic Performance: reaches a sound reduction rating of STC 43(better than 4.5″ batt-insulated stud wall)

7. Seamless: No vertical metal supports reauired

8. Lightweight: 7mm or 8mm thick channel glass is easy to design with and handle

9. Bird-Friendly: Tested, ABC threat factor 25.
