Can You Add Resilient Channels to Any GA-600 Listed Floor-Ceiling or Wall System?

Question: Can resilient channels be added to any listed floor-ceiling or wall system in GA-600, if not listed in the system description?

Answer: A resilient channel is a thin metal strip used in wall and floor-ceiling construction that can enhance sound isolation performance, provided it is installed correctly according to the manufacturer's instructions. Mounted perpendicular to the framing and spaced as specified in the assembly details or by the manufacturer, the drywall is attached to the channel rather than directly to the framing. This creates a separation that helps block sound vibrations, thereby reducing the amount of noise that travels through the wall or ceiling.
