Has anyone any experience of using Rigidur boards on their project? I was planning to use Fermacell for racking strength and sound dampening but was concerned with the price, so am looking round for alternatives. -

I have a job planned that will use Fermacell and your post got me looking at Rigidur as an alternative. Not many stockists but the prices I saw are at least as expensive as Fermacell. No mention of any specialist board jointing so looks like its put up like normal plasterboard and taped/filled/plastered as normal.
One possibility I looked at was attaching ply/osb sheeting then putting thin plasterboard on top. Gives extra strength, allows screwing directly into finished walls and at a comparable price for materials. Decided against in the end as I wanted to completely DIY and have zero plastering skills. -

I have done exactly this and it works brilliantly. Be aware that the OSB is a slightly different sheet size to the plasterboard. The OSB was a metric equivalent of an imperial size 2440x1220 (8'x4') while the plasterboard was 1200x2400. This was not a big deal but worth bearing in mind when fixing uprights. -

Thanks guys. interestingly I had a meeting yesterday with a long established drylining company and they also suggested the OSB method as a cost effective solution where racking strength was required. -

just to chip in, although it seems you've found a good solution in the OSB/ply method, I've been using fermacell on my build for the ceiling and internal partitions and have been impressed by it.
It is more expensive but the boards are loads tougher, you can drill, sand, rasp, saw them very easily for intricate shapes and the finishing of a quick fill then a skim with their own brand skim is really easy and quick. Although I haven't done the final budget I don't think it's cost me any more overall as I have not had to get a plasterer to skim the boards.
I would recommend them for anyone who is using their own DIY labour as it turns a skilled subcontractor job into one that can be done by by yourself.
The only thing to bear in mind is that the boards are heavy (not really a one man lift) and it's really helpfull if you have a local stockist (we used Bradfords).
The glue jointing system is also really good for avoiding cracks although it can get a bit messy! -

I have also used Fermacell and can recommend it for all the reasons by b..b above. On the weight issue we used 12.5mm and 10mm boards. It is obvious from the measurements that the former is 25% heavier than the latter which is why it was used in areas where we wanted more sound attenuation but by heavens that 25% extra makes a heavy board very very heavy!
