One of the most effective low -cost methods for reducing sound transmission through walls and ceilings. Resilient Channel dampens sound waves effectively, dissipating the energy and reducing sound transmission by suspending the drywall = inch from the wall stud or floor joist. Important: Remember that resilient channels should not carry heavy loads such as bookshelves, cabinetry or heavy light fixtures. Avoid situations where the resilient channel is placed between layers of drywall or other panel material.
