    I'm using the SEAI trying to work out heat loss for a 2 storey cavity block house built c 1998 and need some help to determine the correct U values for :

    • Walls - made up of (outside to in) - approx 12mm waterproof render, concrete cavity block, 50-70mm pink fibreglass roll insulation between timber battens, clear plastic sheet barrier, 12mm plasterboard, paint
    • Ground Floor - concrete with carpet/vinyl/laminate flooring (8mm) and AFAIK there is no insulation underneath

    Any help would be most welcome. TIA.
