channels that produce clean glass spans. The rails are paired with
CRL-Blumcraft panic handles, which feature a slim, elegant tubular
design that enhances safety, security, and aesthetics. Taller glass spans,
made possible by using 13/16-in. custom laminated glass, improve
STC ratings for reduced sound transmission. The sprawling glass walls
feature a custom dot-pattern frit that adds a distinct design element
while providing privacy.
The grand atrium is flanked by walkways lined with the company's
GRS Taper-Loc glass guardrail system. The guardrail offers the only
ICC-ES approved base shoe system available for glass railings. It also
complies with 2015 IBC updates to ensure codes are met. The guardrail maximizes transparency and natural-light diffusion.
With 777 Aviation, SOM went beyond the traditional scope of a

"Given the performance criteria for the new fenestration and our
goal of having a minimalist aesthetic, there was no other option than
the Entice entrance system we specified," said Susan Bartley, AIA,
LEED AP, and project manager at SOM Architecture.
The curtainwall and entrance system helped execute SOM's objective of giving the facade an updated, minimalist aesthetic that did not
