    What size battens should I use for 12mm hardiebacker? Also what sized concrete screws should I use?

    I plan on insulating in-between battens.

    How much insulation do you want? Some might put in 20mm of insulation, while others put in 200mm of insulation. The battens would be the same thickness as that of the insulation.

    Hey, just the right batten to support the hardiebacker and tiles, in some of the technical documents it Says 32mm or 35mm screws to secure the 12mm hardiebacker
