1 in x 2 ft x 12 ft Continental Weather Defense Shaftliner Type X Gypsum Board

Weather Defense Shaftliner Type X is designed for use in lining elevator shafts, ventilation shafts, 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, moisture-, mildew- and mold-resistant gypsum core enhanced with glass fibers for strength and additional fire resistance. Its fiberglass matting eliminates paper, a potential food source for mold, and may help reduce remediation and scheduling delays making Weather Defense Platinum Shaftliner Type X a great alternative to traditional paper-faced shaftliners.
