Weather Defense Sheathing is a moisture- and mold-resistant exterior wall sheathing designed to be covered by an exterior-finish cladding such as siding, brick, masonry veneer or wire-lath stucco. Its specially formulated non-combustible, moisture- and mold-resistant gypsum core is covered with a coated fiberglass mat on front, back and long edges. Weather Defense Sheathing can be used in Exterior Insulation and Finish Systems and as a substrate for air and water-resistant barriers including wraps, self-adhesive membranes and liquid-applied coatings. Weather Defense Sheathing offers superior resistance to normal weather conditions and will provide protection in most applications.
