Hello all,
Just thinking about the apps. of the RC.It is used mostly on the walls and therefore one would get the impression that it was mostly designed to work properly installed on a vertical frame and then the drywall(or whatever you wanna call it ) is Hung on it. So the weight is sort of pulling down.If used on flat ceilings the situation woul be similar but with weight pulling the RC in a slightly different "direction". But what I'm wandering is:
How will it behave in a vaulted ceiling application?Would there be a Possibility of "pulling" the channel in an undesired direction so to shorten it out at some point?I mean if you have a few layers hanging on it, and all this is on a 25 degree angle how would it handle it?(of course you would compensate for extra weight with closer channel spacing, but still...) Or does the "RC spring" work in all ways? Anyone used it this way at all? Any resources of how the RC works in this regard?
Thanks all very much

edit:ooops can't spell

On a wall, you put the wide section up on all but the bottom course, which is usually fastened with the wide part down; this is mainly to make it easier to fasten. Having the channel open "up" means that gravity will tend to WIDEN the gap between studs and wallboard, keeping the RC from "shorting out" - on flat ceilngs, you can put all RC facing the same way; although I tend to put at least the last one facing the opposite way, just because it seems like it would counteract the tendency of the ceiling cladding to sag to one side.

For a vaulted ceiling, you just consider it as a wall that's not quite vertical; put the open end of the RC to the upper side when fastening the RC to the joists. That way, you still get the tendency for the RC to "spread" instead of collapsing... Steve

Thanks Steve, you're the man
It's just that I've never seen RC except for in pictures so I was a bit puzzled as in how flexible the steel actually is etc. etc....Your comments make sense, I'll keep them in mind.
Thanks much

cheers
