I want to put underfloor heating. but it wil be on plywood. the question are can i fix it straight to the floor of do i need a board/insulation to fix onto. i have the joists already insulated with 225mm warmcell and the other question does anyone know about the speical concrete mixes for this typpe of work and will i need a plastic underlay for the floor on the plywood??.
