1" is ok but can you try to get more on the outside ? even dig down prior to foundation you can install the insluation on the outside of the wall as well.. Good Luck

    Pole barn radiant system

    Any opinions on properly insulating underslab of a pole barn
    type constructed building, specificaly perimiter insulation?
    Building is new construction, R-19 walls, R-38 cielings,
    48'x60'x12' with he-pex radiant system. If I used 2" foam
    underslab & 1" perimeter foam only the thickness of the slab
    ( 6" ) instead of possibly going 2' deep with the perimeter
    insul, do you think I would have a much greater outward loss? In other words, do you think I would have a beauty of
    a flower garden around the structure in mid january in the
    northeast????????????? Thanks AL
