Metal ceiling renovates office building

Carson Guest Interior Design specified a metal ceiling system to meet project goals to renovate Alston and Bird LLP's law office in Atlanta. The modern, sustainable, 365,419-square-foot office is located at the top 16 floors of One Atlantic Center, a 50-story office tower. The top three floors were converted to include a reception area, dining area, mock courtroom and conference rooms.

Pods of curved metal ceiling clouds were suspended above the dining area and videoconference room to control acoustics. Nine aluminum ceiling clouds constructed with Armstrong Ceiling and Wall Systems' custom-curved MetalWorks Torsion Spring panels with a Wild Cherry Reflections laminate finish were installed in the 4,000-squarefoot dining area. Seven clouds are 12 feet by 22 feet and two are 9 feet by 22 feet. The panels were manufactured in 36-inch by 7-foot, 6-inch modules with a 1/2-inch reveal around each module and 6-inch Axiom perimeter trim. They are perforated and backed with acoustical fleece and acoustical infill panel designed to provide a 0.9 noise reduction coefficient, which absorbs 90 percent of sound.

Rita Guest, of Carson Guest Interior Design, says the owner requested a contemporary design for the various spaces. "These are the public areas of the firm where most of the meetings take place," she says. "We didn't want flat white acoustical ceilings. The ceilings needed to be interesting and create the illusion of height."

Five aluminum ceiling clouds constructed with MetalWorks Torsion Spring custom curved panels in a Whitelume finish were installed in the 1,400-square-foot videoconference room to provide high light reflectance, volume and height to space. The clouds are approximately 8 feet by 23 feet, 6 inches. Narrow linear lighting was installed on the same plane as the panels and the clouds are framed by 6-inch perimeter trim.

Guest says it's a very bright, white ceiling. "It's a videoconference room, so light reflectance was important and it gives the space a contemporary feel," she says. "They have acoustical value, they are accessible, and they work with the contemporary aesthetic of the design for the new space."

Gregg Hunter is regional sales manager at Armstrong Ceiling and Wall Systems. "The advantage with metal is that you can get much better acoustical performance with smaller perforations, which makes for a more attractive visual," Hunter says. "To get the same level of acoustical control with wood, the perforations would have to be much larger, which would be very unattractive at that ceiling height."

The 2015 Construction Excellence Award competition of the Ceilings and Interior Systems Construction Association awarded the project Silver in the ceilings category, South region.
