What is a resilient bar and how do I use it?
Knauf Resilient Bar Knauf Resilient Bar works by reducing the level of direct sound transmission through a structure. The bar has one flange that is screwed to the supporting framework and a separate, corrugated, flange that receives the plasterboard drylining – thus partially isolating the drylining from the supporting structure. Installation – The resilient bars should be mounted perpendicular to the line of the supporting framework, in parallel rows, at the correct centres given for each application. Where more than one bar is used for a continuous run, the bars should be butted together, directly over a support, and both base flanges screwed to the support. The resilient bars should be fixed at a maximum 600mm centres using Knauf Drywall Screws of the following lengths: Into timber: 36mm Into metal: 25mm The cut ends of boards must be supported on resilient bars. The fixing centres for the boarding are as they would be if resilient bars had not been used for the application.
