About this product
Gold Bond® eXP® Sheathing is a moisture and mold resistant gypsum panel designed for attachment to the outside of sidewall and soffit framing as a water resistant underlayment for various exterior materials. eXP Sheathing is manufactured with an enhanced moisture and mold resistant core and facer. The facer is composed of a coated fiberglass mat with Purple® color which provides superior weather resistance capabilities. eXP Sheathing is lightweight, scores and cuts easily, and is specially coated on the front, back and sides for easy handling. Uses: eXP Sheathing can be used in both wood and metal stud construction to provide fire resistance, weather protection and to add to structural strength. eXP Sheathing can be used as a substrate for various air and water resistive barriers including building wraps, self-adhesive membranes and liquid applied coatings. It can be used as a component in curtainwall or Exterior Insulated Finish Systems (EIFS), and under various exterior finishes such as metal, vinyl, wood or fiber-cement siding; brick/stone veneer, or conventional stucco.
