Built-in weather and fire protection
Provides superior water resistance
- Dimensionally stable base to build high performance exterior wall assembly.
- Provides superior mold and moisture resistance.
- Type X core is fire resistant and an approved component in UL fire-rated designs.
- Offers a 12-month extended exposure warranty for typical weather conditions.
Gold Bond® eXP® Fire-Shield® Sheathing consists of a moisture- and mold-resistant gypsum core encased in a coated, specially designed PURPLE® fiberglass mat on the face, back and sides. It is available in a Type X core. The glass mat is folded around the long edges to reinforce and protect the core, and it provides superior weather resistance.
Use eXP Sheathing for attachment to the outside of wall and soffit framing as a substrate for exterior cladding.
GridMarX® are printed on the glass mat surface to help installers instantly identify stud locations and make accurate cuts without having to pencil in or snap chalk lines.
For 1/2” sheathing with a regular core, not used in UL fire-rated designs, see Gold Bond® eXP® Sheathing.
Check the Fire and Safety Information for a more complete explanation of how fire resistance ratings work.
