eXP Sheathing is manufactured with an enhanced moisture and mold resistant core and facer. The facer is composed of a coated fiberglass mat with National Gypsum’s original PURPLE color which provides superior weather resistance capabilities. It is produced in 1/2″ and 5/8″ thicknesses, 4′ wide in 8′, 9′ and 10′ lengths. eXP Sheathing is lightweight, scores and cuts easily, and is specially coated on the front, back and sides for easy handling.
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.
