Size of wooden battens and costing?

SAGZ

Hi all,

I’m placing celotex insulation over solid walls, battening over this and then placing plasterboard on top. I was wondering what size battens I should use? and the approximate costing per metre.

Google seems to provide contradictory information. I'm using 50mm insulation and 12mm plasterboard. The Walls are approximately 4.6m in length.

I appreciate any help/advice.

Thanks

mmm should the celotex not go in between the battons?

Or are you using GA4000 or PL4000?

or fix the PB direct onto the celotex with dot & dab adhesive.
no battens required.

Hi JustJohn, I've looked online and the general opinion is that you insulate and then batten.

Apologies, I also forgot to mention that these are external walls if this has any influence with regard to maintaining an air gap.

Yes John, you are right. I'm going to be using GA4000. I've read so much on the insulation procedure but there is little info on the battening, which is the simple part i assume...

Thank you very much John.

From PDF: " Battens should be minimum 50mm x 25mm treated softwood"

2x1 inch, less than a pound per m. at wickes.

for 2.4 high walls, I would use 2x1 battens fixed at 400 centres, you will need to use a minimum of 5x 4" screws per batten and make sure you knock the wall plug well into the brickwork and not just the plaster.
