eXP Sheathing is a moisture and mold resistant gypsum board designed for curtainwall 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 which provides superior weather resistant capabilities. It is produced in 1/2” and 5/8” thicknesses, 4’ wide in 8’, 9’ and 10’ lengths. eXP Sheathing is light-weight, scores and cuts easily, and is specially coated on the front, back and sides for easy handling.

Basic 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. The 5/8” eXP Fire-Shield® Type X gypsum panel can be utilized for exterior fire-rated wall and soffit assemblies.
