Extra protection against mold and mildew
- Fire barriers for cavity shaftwalls, stairwells, and area separation walls.
- Mold and moisture resistant, provides extra protection against mold and mildew.
- Type X core is fire resistant and is an approved component in UL fire-rated designs.
Gold Bond® Shaftliner XP® gypsum panels consist of a mold-, mildew- and moisture-resistant Type X gypsum core encased in a mold-, mildew- and moisture-resistant, 100% recycled PURPLE® paper on the face and back sides.
Shaftliner XP is 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 beveled 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 elevator shafts (1-4 hr.) stairwells and area separation fire walls 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.
