Weather Defense drywall 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.
Weather Defense is specially formulated, noncombustible, moisture- and mold-resistant gypsum core is covered with a coated fiberglass mat on the board's front, back, and long edges. Weather Defense can be used in exterior insulation and finish systems (EIFS) when specified by the EIFS manufacturer, and as a substrate for air- and water-resistant barriers, including wraps, self-adhesive membranes, and liquid-applied coatings.
Weather Defense offers superior resistance to normal weather conditions and will, in most applications, provide protection from exposure to the elements for up to 12 months (subject to the terms, conditions, and exclusions of Continental's limited warranty). Use of a flexible sealant to fill all exposed cutouts and joints will afford additional protection when construction is delayed for an extended period.
Weather Defense is lightweight; scores, cuts, and fastens easily; and has specially coated facers to provide irritation-resistant handling. It is designed for use in applications that require direct mechanical attachment to wood or metal framing, or attachment to steel-stud curtain walls. Exterior cladding should be attached mechanically through the sheathing and directly to the framing.
