    OX-IS structural insulation vs OSB

    OX-IS is the all-in-one product that allows you to meet building code requirements for structural sheathing, continuous insulation, weather and air resistive barrier performance.

    A Few Facts About Uninsulated Sheathing Like OSB:

    • OSB does nothing to reduce home energy use. (RESNET HERS® reports)
    • OSB actually promotes and accelerates home energy loss due to thermal bridging. (DOE)
    • OSB homes cost more to own than homes with OX-IS/continuous insulation.(DOE)
    • OSB homes are worth less than homes built with OX-IS/continuous insulation. (HUD Green Appraisal Requirements)
    • OSB/uninsulated sheathing is a primary culprit for wall cavity moisture production. (DOE)
    • OSB homes require larger, more expensive heating and cooling (HVAC) systems. (DOE)
