Exterior gypsum sheathing is built for use on the exterior of buildings as an underlayment for wood, metal, or vinyl siding, and other exterior siding materials. It has a Type X fire-rated core with water-resistant treatment and features water-repellent paper on both sides. This gives gypsum sheathing enhanced protection against weather, moisture, and fire.
Wrap up the outside roof or side panels of any commercial or residential building project with our selection of exterior gypsum board.
