I want to fit undertile electric heating in my bathroom. I have bare floorboards on joists and will be using tile adhesive and floortiles above the heating mat. Question is, what do I need to do to the floorboards (not t+g, just old fashioned butted boards). I thought I would put a screw a sheet of plywood to the boards before laying the mat, but notice there are various thicknesses, plus you can also get insulated board.
Can someone advise me on the type and thickness of material to use?
