Hi All,
I've got a situation I'm not sure how to resolve and wanted some advice / experience if possible please. The bathroom I'm looking at has 2 outside walls, both of which are stone with no cavity insulation. The customer is requesting some insulation is added to the wall interior prior to the walls being tiled. In addition, they would like to have stone tiles (to be confirmed exactly what) on the walls, floor to ceiling. The bare wall is very uneven as is normal with stone walls, which makes things pretty awkward to fit to it. My current thoughts are to batten the wall with 2x2 timber every 300mm with cross noggins and then fit 2inch kingspan/celotex in between. (Issues with trying to get good fixings into stone are that the mortar usually falls to bit and sometimes drilling stone is difficult to get an acuarte position.) I would then screw hardibacker to the timbers and tile directly onto that. My concerns are that the 2x2 battening is going to be a nightmare to get vertical and flat across the length of the wall. Dot and dab a composite plasterboard with insulation attached would be my prefered option but I am aware that does not comply with regs for the weight of the stone tiles. I could build a free standing stud wall in front of the stone wall (say 3x2 timbers) which would remove any issues with drilling the stone and getting a good fixing ???? Hardibacker on the front of this and away we go ?
Anyone had any similar situations as this previously or can offer any suggestions / best practise ?
Thanks is advance
