Currently have insulation covered with backing board which has to be removed to do electric work,was told I could just put plastic down on ground instead of replacing between joists with insulationWhats the right and best way?
I own a mobile home myself and would strongly suggest the insulation between the joists, and then a plastic sheeting placed over that to make it as airtight as possibleThe skirting on these things cannot keep wind out, and any insulation placed on the ground inside the skirting is going to sit in the water potentially moldingAdditionally every one who has to open the skirting is going to kick that insulation out of the way and your going to have to keep fixing itOn the other hand, the money you would save on insulation, you could give to the gas company this year, and again next year, and the next and.
