Inquiry (采购产品): Sound Transmission I am working on a Multi family Housing project in Houston the IBC states that I need a minimum sound transmission class of 50 on the tenant separation wall. What do you recommend? Have you done a study and or calculations using a double 4" wall w/ 1/2" gyp board each side and sound batt? If so what rating would the sound batt have? Can you send specifications? I need to specify an assembly meeting a min STC of 50. What do you recommend? **** Hidden Message ***** James Fox 2555 Temple Trail Winter Park, FL 32789 USA Company: Fugleberg Koch Architects Title: Architect Phone: 407-629-0595 Fax: 407-628-1057 E-mail: jimf@fuglebergkoch.com **** Hidden Message ***** jimf@fuglebergkoch.com
