The main challenge for the renovated façade at The Children’s Hospital of San Antonio was to create tall, relatively lightweight façade units that could be quickly pre-assembled and installed onto slim concrete eyebrows. This was critical, as the available work area was insufficient to assemble the units on site.  The design team turned to Bendheim’s channel (U-shaped) glass for its remarkable structural qualities, allowing it to span great heights under high wind loads. On this project, the glass channels reach spans from 10 to 19 feet in relatively lightweight ¼” thickness. At only 4.5 lbs/sq, they meet the weight limits of the building’s concrete eyebrows, a feat unachievable by conventional flat glass.
