dnb Posted August 19, 2020 Share Posted August 19, 2020 I am curious as to what size battening people have used for their GSE in roof PV installations. I think mine needs to be 100x25 according to the GSE manual. But there is no further guidance on strength etc. Link to comment Share on other sites More sharing options...

willbish Posted August 19, 2020 Share Posted August 19, 2020 25x50 but doubled up where necessary. I found the GSE instructions unnecessarily complicated with regard to batten spacing. If I remember correctly, the only figure you really need is the 'additional line' which differs depending on which size panels you have. Lay down extra battens if the mount fixings are unlucky enough to miss a batten. 1 Link to comment Share on other sites More sharing options...
ToughButterCup Posted August 19, 2020 Share Posted August 19, 2020 25 by 50, doubled in one or two places.... The blue ones, not the knotty sort. 1 Link to comment Share on other sites More sharing options...

I assume that is in inches (unless it's a model house ? ) So 100x25mm - same as the GSE spec demands. Did you use any particular graded timber? 5 hours ago, NSS said: but doubled up Was hoping someone would say that! Thanks all. Looks like I can carry on with using my blue slate battens. Most of the time they are in more or less the right places. Link to comment Share on other sites More sharing options...

Did you use any particular graded timber? Nope, just the rough-sawn tanalised stuff from the local yard. While I *did* follow GSE's spec, it worth pointing out that a. the thickness needs to match your tiling battens and b. the wider the plank the easier it is to aim for...
