Excellent. Thanks for the info! I see now :) Sorry!! I didn't realise that the Gyplyner channels were actually different to the c-studs. Think I got confused, as I've seen quite a few places refer to the channels as GL1 studs and then just assumed that they were actually c-studs. lol

So, c-studs would just sit between the top and bottom tracks, without any need for brackets and still be strong enough to resist any forces acting on them? It's pretty important that the wall doesn't flex at all, as it will have a corner shower against it.

It's also a small room, so the gyplyner system may be better if it saves a little space. Also don't want to make the reveal on the window too deep, or it'll look silly for such a small room. Though I think there would only be about 10mm in it, between the two systems? Though still need room for 25mm of insulation.

Even B&Q sell the Gpyroc C-Studs these days in 2.4m & 2.7m lengths if you only want a few.

My preference is to use the brackets as it is a 'stronger' wall.

Having given you a couple of ways to deal with the lining channels which abut the two existing walls. The easiest way to do this and how I do it, would be to use track to go up the wall. So in effect you are making a frame with the track on ceiling, floor and up the walls and then infilling every 600mm centers with the lining channels.

Should have told you this earlier but was answering your specific question about the problem and only just twigged onto the fact that I hadn't advised you of this.

Thanks for your help! Think I should be alright to give this a go now.

Darrenba, do they? Took a look on their site and couldn't see any. It was the gyplyner channels I wanted really (made a mistake calling them c-studs). Ta anyway.
