Made of 0.5mm steel the Knauf resilient channel is a very effective, low-cost methods of improving sound transmission loss through Knauf drywall partitions. It is used as a cross-furring member fixed to the Knauf CW studs ready for the resilient attachment of gypsum boards; the knurled face makes the gypsum board application easier. Knauf resilient channel should be installed perpendicular to the steel framing with the attachment flange of the resilient channel installed along the bottom edge. Field of Application: Knauf Resilient channels are to be installed perpendicular to the steel framing CW studs. The resilient channel is to be positioned with the mounting flange directly over the steel framing CW stud, and attached using the Knauf LN screws directly through the mounting flange. Resilient channels should be installed with the mounting flange of the resilient channel down, except at the floor or starter row where the mounting flange may be installed with the flange up to accommodate fixing to the steel framing CW studs.
