Carlson Restaurants Worldwide Inc., a global
restaurant company specializing in casual and
sophisticated dining segments, operates franchises
in 746 restaurants in over 50 countries. Company
restaurants include familiar names such as: T.G.I.
Friday’s, Friday’s Front Row Sports
Grill, Friday’s American Bar, Timpano Italian
Chophouse, Samba Room and Pick Up Stix.
Carlson’s new 130,000-square-foot corporate
office building, located just steps away from
active railroad tracks, sees train traffic throughout
the day. To reduce the intrusive blare of the
trains passing by, the building’s owners
wanted to install high sound control glass in
several offices including that of the CEO, the
boardroom and other offices located near the train
tracks. “The din of the trains is extremely
disruptive and could have had a negative impact
on workplace productivity,” notes Jack Wickstrom,
Dallas sales manager for Arch Aluminum & Glass
Co.
To achieve an STC rating of 45 in the CEO’s
office and boardroom and an STC rating of 42 for
the other offices closest to the train tracks,
the architects chose laminated glass with a PVB
interlayer. “The sound isolation resulting
from the acoustical glazing was remarkable,”
says Wickstrom. “The occupants of the building
can now go about their workday without being disturbed
by the racket of the trains clamoring by.”
The following glass configurations were used
to achieve the optimal noise reduction for the
Carlson Restaurants building:
| Glazing
One: |
1 3/16"
overall insulated thickness to achieve an
STC of 45: |
| Outboard Lite: |
1/4" Optigrey Tempered

The 130,000-square-foot
Carlson Restaurants Worldwide office building
is located just steps away from active train
tracks The noise of the trains is virtually
unheard by Carlson employees due to laminated
glass windows with a PVB interlayer. |
