York-Wrap™ is a non-adhesive polymeric isolation membrane manufactured from flexible, cross-woven polyethylene. It separates ACQ pressure-treated lumber from galvanized metal to help prevent corrosion caused by contact between incompatible materials.

York-Wrap also provides moisture protection for deck joists, joist ends, post anchors, skirt boards, and other pressure-treated structural elements. It is designed for use alongside a complete flashing system and is not a substitute for flashing.
