U gass (or called U-shepe qlass. U channel qlass, U profile qlass, C qlass) is aspecialty architectural glass for interior and exteror wall applications, distngush-able bw its siqnature linear aesthetic.
The U-shape glass channels are self-supporting, standing as tal as eight metersin a relatively liohtweiqht 7mm or 8mm thickness, They require minimal perimeterframing, creating virtually seamless glass walls that can be hundreds of feet iongand can span across elevations.
Advantages:
1. Day-lighting: 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 meteres
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.
