I'm planning to insulate my cellar with Gutex wood fibre (the cellar is clo se to the Gutex factory, and yup, that means "not in England"). Gutex reco mmend their Thermosafe-wd with a humidity variable barrier like Proclima In tello, and then battens fastened through the insulation to the wall (with b oards over the top).
What sort of fastenings would people use? I could just use frame fixings, but I'm a bit concerned about all that metal creating a thermal bridge.
Something like

6/dp/B001L5SLKE would be effective, but would cost more than the insulation .
Perhaps

-of-24/99789?kpid=99789 plus a frame fixing at the top.
Also, how thick would you make the battens? 25x50, 50x50, something else? Finally, what spacing for the battens and fixings in the battens?
