The ThermoPLY® system does what OSB and building wrap do, but far better and in a significantly lighter, more economical, and single-component solution. Featuring high-strength cellulosic fiber boards with a protective polymer exterior layer and a water-resistive coating on both sides, the ThermoPLY system creates a lasting best-in-class air and moisture barrier. ThermoPLY boards are compatible with OX Arctic-Flash®, TITAN® Butyl Flashing, and OX SeamTape®. ThermoPLY comes with a 30-year limited warranty.
