PrimeWall Resilient Channel is a highly effective, efficient, low cost product designed to greatly assist in the marked reduction of sound through partitions and ceiling assemblies. To achieve this damping of sound waves, gypsum wallboard is suspended ½" from the stud or joist member. Additional sound mitigation can also be achieved through the use of sound attenuation blankets within the wall or ceiling cavity. Sound absorption can be maximized by utilizing sound attenuation blankets within the wall or floor cavity. PrimeWall Resilient Channel is manufactured from 25- and 20-gauge corrosion-resistant galvanized steel and is available with single or double legs. Each PrimeWall® Resilient Channel has a 1.25" screw flange and is commonly used in wall applications. Double Leg PrimeWall Resilient Channel has two legs for rapid installation, and is typically used for ceiling applications with multiple layers of gypsum board. While Double Leg PrimeWall Resilient Channel is easier to install, it results in a lower STC rating.
