Gold Bond® BRAND 1" Fire-Shield® Shaftliner XP® gypsum panels consist of a specially formulated fire-resistant and mold-resistant Type X gypsum core encased in a heavy moisture/mold/mildew resistant, 100% recycled 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 have a double-beveled edge for ease of installation.
- 1" Shaftliner XP panels are designed to be used to construct lightweight fire barriers for cavity shaft walls and area separation walls in multifamily housing. The panels are key components in the I-Stud Cavity Shaftwall System and the I-Stud and H-Stud Area Separation Wall Systems.
- Resists growth of mold and mildew per ASTM D 3273.
- Lightweight, cost-efficient material.
- Shaftliner is easily cut for quick installation.
- The gypsum core will not support combustion or transmit temperatures greatly in excess of 212°F (100°C) until completely calcined, a slow process.
- Expansion and contraction under normal atmospheric changes is negligible.
- UL Classified for fire resistance, surface burning characteristics and non-combustibility.
- Shaftliner XP may be substituted for National Gypsum's Gold Bond® BRAND Fire-Shield® Shaftliner in Cavity Shaftwall, Area Separation Wall Systems and solid laminated partitions.
Gold Bond® BRAND 1" Fire-Shield® Shaftliner XP® was designed to provide extra protection against mold and mildew compared to standard wallboard products. When tested by an independent laboratory per ASTM D3273 ("Standard Test Method for Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental Chamber"), Shaftliner XP achieved a score of 10, the best possible score for this test.
*The use of Shaftliner XP in actual installations may not produce the same results as were achieved in controlled, laboratory conditions. No material can be considered "mold proof", nor is it certain that any material will resist mold indefinitely. When used in conjunction with good design, handling and construction practices, Shaftliner XP can provide increased mold resistance versus standard shaftliner products. As with any building material, avoiding water exposure during handling, storage, and installation, and after installation is complete, is the best way to avoid the formation of mold or mildew.
