(Valley Forge, Pa.) – Acoustic control is always a vital factor in designing facilities that host live performances of music, theater and dance. Unwanted noise, such as the sound of mechanical equipment operation, is simply unacceptable.
When designing an HVAC system for the new Kauffman Center for the Performing Arts in Kansas City, Mo., mechanical and electrical engineers W. L. Cassell & Associates knew lining the system’s ductwork with sound-absorbing fiberglass insulation would be an important strategy in preventing equipment noise and crosstalk from disturbing performances. For optimum acoustic control, the Kansas City engineers specified CertainTeed(R) ToughGard(R) 2 Textile Duct Liner.
“We specify textile duct liner all the time for acoustically sensitive projects, and we’ve been very happy with the ToughGard 2 Textile Duct Liner,” says Bill Whitman, Senior Vice President of W.L. Cassell & Associates. “It has better acoustic control than other duct liners we’ve come across.”
Used primarily as an acoustical liner in HVAC sheet metal ducts to absorb unwanted crosstalk, equipment and air rush noise, ToughGard 2 Textile Duct Liner is a durable, abuse-resistant and easy-to-clean product. Featuring a higher R-value, ToughGard 2 exceeds the thermal performance of all competing duct liners, and with a unique, enhanced surface, it is also more moisture-resistant than standard duct liners. Moisture that enters a duct system insulated with ToughGard 2 beads up and stays beaded, allowing airflow to evaporate the moisture before it can be absorbed into the liner, avoiding potential mold and microbial growth. ToughGard 2 can be used in most types of comfort heating and cooling duct systems operating at velocities up to 6,000 feet per minute and temperatures to 250ºF. The product has achieved GREENGUARD(R) certification for superior indoor air quality, helps meet ENERGY STAR(R) requirements and can contribute to Energy and Environmental Design (LEED) credits through the U.S. Green Building Council (USGBC) and the National Association of Home Builders’ Green Building (NAHB) Guidelines.
Ducts are being fabricated and installed by Lenexa, Kan., contractor Cates Sheet Metal. The project will feature 256,989 square feet of 1-inch ToughGard 2 and 270,000 square feet of 2-inch ToughGard 2, which Cates Sheet Metal purchased from CertainTeed insulation distributor Bay Insulation of Kansas City Inc. Duct installation began in June and is expected to continue through to next year. In addition to using the duct liner to insulate ductwork, 300 to 400 feet of the duct liner will be used to insulate large concrete plenums in the performing arts center.
“We’re using a low-velocity displacement HVAC system under the seats, and we’re feeding the air into the massive concrete plenums instead of ducts,” Whitman says. “So, we’re also insulating the plenums with the ToughGard 2 Duct Liner for acoustic control.”
“ToughGard 2 is designed to meet the tough standards of the most discerning mechanical engineers, and like original ToughGard Duct Liner, has become a favorite in the industry,” says Renee Chesler, Vice President and General Manager of CertainTeed’s Mechanical Insulation Business. “It provides unparalleled acoustic, thermal and moisture control, making it ideal for performing arts venues, where the comfort and positive experience of an audience means everything. We are pleased to be part of this exciting project at Kauffman Center for the Performing Arts.”
Located in downtown Kansas City, construction of the Kauffman Center for the Performing Arts began in October 2006. The impressive 284,780 square-foot structure is the product of an internationally renowned designed team, consisting of Moshe Safdie & Associates (Somerville, Mass.), Theatre Projects Consultants (London), Nagata Acoustics (Tokyo) and BNIM Architects (Kansas City). It will feature two state-of-the-art performance venues: a 1,800-seat proscenium theater and a 1,600-seat concert hall and will be the new performance home of the Kansas City Symphony, the Lyric Opera of Kansas City and the Kansas City Ballet. Kauffman Center for the Performing Arts is expected to be complete in time for the 2010 to 2011 performance season.
