Gold Bond® BRAND Fire-Shield® Shaftliner XP® Gypsum Panels with Sporgard™* consist of a fire-resistant Type X gypsum core encased in a heavy moisture/mold/mildew-resistant, 100% recycled, National Gypsum's original PURPLE® paper on the face and back sides.
Shaftliner XP was designed to provide extra protection against mold and mildew. The face paper is folded around the long edges to reinforce and protect the core, and the ends are square-cut and finished smooth. Long edges of panels are beveled for ease of installation.
Shaftliner XP panels are designed to be used to construct lightweight fire barriers for cavity shaft walls (1-4 hr), stairwells and area separation firewalls in multifamily housing. The panels are key components in the I-Stud, C-T Stud and C-H Stud Cavity Shaftwall Systems and the H-Stud Area Separation Fire Wall Systems.
