Cavity Battens

[benben5555]

Hi, what timber have people used for their cavity battens. Roof battens (25x50) would seem to do the job, but I don't know if a untreated timber would be better. I can't seem to find much untreated wood of a suitable size. Thanks

When you say cavity batten , do you mean for the service void internally,  or for external cladding

Sorry yes, I meant service void

I have used a mixture in the past on different builds ranging from tiling batten  35mm sq untreated etc .

Personality I prefer a slightly larger void to stop anything puncturing the vcl .

On my own builds or for friends I use 3x2 cls , dry, nice and wide for fixing your plasterboard and deep enough to protect the vcl and get electrical back boxes in etc

47x42mm is what I've used. You can nailgun them then, if that's any use to you. 

 

Also 50mm mineral wool insulation is readily available, 

 

I wouldn't object to wider mind you.
