    Sounded like you were giving directions tbh.

    Any floor insulation will need to be worked to a u value not a thickness of insulation. The thickness of insulation will be affected by the complete make-up of the floor.

    But do you think a rank amateur who has to ask has a clue about this? Is he going to do calculations? (no)

    50mm of polystyrene over the correct grade visqueen will be worlds apart from the damp floor/subfloor he likely has now. Expanded pu probably 50% more effective per thickness

    Building regs will give the requirements, but I sense this might not involve them, :A:A
    I like the thanks button, but ,please, an I agree button.

    Will the grammar and spelling police respect I do make grammatical errors, and have carp spelling, no need to remind me.;)

    Always expect the unexpected:eek:and then you won't be dissapointed

    Hence why I'd tell them to stick 100mm (at least) in there. It's not easy to upgrade it later so do it right, do it once.
