Weather Defense Shaftliner Type X drywall is designed for use in lining elevator shafts, ventilation shafts and stairwells, for area separation walls in residential housing, and for other interior building applications requiring fire resistance.
Weather Defense Shaftliner Type X has a specially formulated, noncombustible, mold-resistant gypsum core enhanced with glass fibers for strength and additional fire resistance. Its fiberglass matting eliminates the need for paper, a potential food source for mold. This characteristic can help reduce remediation and scheduling delays, making Weather Defense Shaftliner Type X a great alternative to traditional paper-faced shaftliners.
Weather Defense Shaftliner Type X panels are only one component of a reliable shaft or area separation wall assembly. To obtain proper fire-rated resistance, the panels must be used as specified in the listed design. (See the Continental Shaftwall design literature or the UL listings for more information.)
Weather Defense offers enhanced protection against the growth of mold and mildew on its surface when compared with ordinary drywall products. Under controlled testing conditions, Weather Defense achieved an average panel score of 10 out of a possible 10, the highest level of performance for mold resistance using ASTM D 3273. As with any building material, avoiding exposure to water during handling, storage, and installation is the best way to avoid the formation of mold and mildew.
Note: Weather Defense Shaftliner Type X should not be used where temperatures exceed 125 degrees Fahrenheit for extended periods of time, or in areas of extreme humidity. The board should be protected from exposure to adverse conditions during storage and construction. Weather Defense Shaftliner Type X is not designed for exterior use or for the exposed element of an unlined air-supply duct.
Weather Defense Shaftliner Type X has been tested for a wide range of ceiling, wall, and enclosure applications:
- Elevator enclosures
- Stairwell enclosures
- Mechanical enclosures for electrical, plumbing, HVAC, and venting services
- Unlined shafts for return-air handling
- Area separation fire walls
Low installation cost: Weather Defense Shaftliner Type X installs easily and quickly compared to block construction. It is lightweight and scores, cuts, and fastens with ease.
Mold resistance: Weather Defense Shaftliner Type X offers enhanced protection against the growth of mold and mildew on its surface and in its core.
Weather resistance: Weather Defense Shaftliner Type X will provide protection from exposure to the elements for up to 12 months in most applications (subject to the terms, conditions, and exclusions of Continental's limited warranty).
Core: Noncombustible, dimensionally-stable, inert gypsum enhanced with glass fibers for strength and fire resistance and chemically treated to resist mold and mildew.
Facer: Coated fiberglass, water-repellent and chemically treated to resist mold and mildew on the surface. Front, back, and edges are platinum colored.
Long edges: Double beveled to ease installation.
Recycled content: More than 90 percent by weight.
Weather Defense Shaftliner Type X can contribute to the U.S. Green Building Council's LEED Credit Qualification in several credit categories to assist in obtaining LEED certification. Visit www.Continentalnorthamerica.com for more details on specific credit contributions and documentation.
Wear safety glasses and NIOSH-approved respirators during cutting, breaking, rasping, or other dust-producing activities.
