When installing RC in runs longer than 3M, should you make the RC joint at a vertical stud or is it okay to have them not touch but just a few mm gap in the middle of a stud wall "space?"

Actually - you should notch them so they interlock in the middle of a stud bay and fasten that joint (before installing the drywall) with a Tek screw.. http://www.bestmaterials.com/detail.aspx?ID=17160 It would be unwise to break the joints at a stud face seeing as you can't screw them at that point - and you do not want this stuff floating at which point you can develop a rather annoying vibration after your wall is a finished.

Thanks Rod but when you say "notch them" do you mean overlap them and screw them together with the screw you linked to?
yes- but you can't just overlap them - you have to actually notch a piece of the base leg so that they will lay flat - you'll see when you get to putting them together. RodThanks Rod but when you say "notch them" do you mean overlap them and screw them together with the screw you linked to?
Sorry for being a bit thick but I'm still not getting it. Surely some part has to overlap so you can screw the ends together? And more confusingly, the suppliers (Sound Service, Oxford) recommend jointing at a vertical stud and screwing both ends to the vertical stud independently!
Sorry - but I don't see it - when I visit their website - more specifically this page (http://www.soundservice.co.uk/installation_resilient_bar.html) directly to the left of the paragraph titled Bar Installation: you casn clearly see the joint in between 2 studs - it's in the upper right hand of the picture........ I have said a number of times that it has to overlap - however - the bottom leg is thick due to the fact that it is rolled - and thus it has to be notched back in order for the top to lay flat...... like I said - when your product shows up it will be quite clear to you what I am talking about........
