Lightweight weather resistant fire barrier
- For lightweight fire barriers for cavity shaftwalls, stairwells and area separation walls.
- Type X core is fire resistant and an approved component in UL fire-rated designs.
- Provides superior mold and moisture resistance.
- Offers a 12-month extended exposure warranty for typical weather conditions
Gold Bond® eXP® Shaftliner consists of an enhanced moisture- and mold-resistant Type X gypsum core encased in a coated, specially designed PURPLE® fiberglass mat on the face, back and sides. The glass mat is folded around the long edges to reinforce and protect the core.
Use it to construct lightweight fire barriers for cavity shaftwalls (1-4 hr.) and area separation fire walls (2 hr.).
For ease of installation, the long edges of eXP Shaftliner are double beveled.
If looking for a shaftliner product featuring a paper face, try Gold Bond® Shaftliner XP®.

APPLICATIONS:
- eXP® Cavity Shaftwall Systems: These systems enclose elevators, horizontal shafts and chase walls in buildings where it is advantageous to erect these walls from one side only. eXP® Shaftliner is the right choice when designing for fire resistance and changing air pressure. Shaftwalls are non-load bearing partitions made up of gypsum board and metal framing. These systems are lightweight and economical compared with conventional shaftwalls.
- eXP® Area Separation Wall Systems: These systems are a popular method of constructing today’s multifamily housing units. These assemblies will be exposed to outdoor elements during the building process, and eXP Shaftliner features a coated glass mat facer and gypsum core that can provide increased protection.
ADVANTAGES:
PROVIDES ADDITIONAL FIRE RESISTANCE
- Features a Type X core making it more fire resistant than ordinary wallboard.
- Approved component in UL fire-rated designs.
- Fire-resistant material with a non-combustible gypsum core helps protect framing elements, even when cladding is combustible.
RESISTS MOISTURE AND MOLD BETTER
- Provides superior water resistance without impeding vapor transmission.
- Resists the growth of mold per ASTM D3273 with a score of 10, the best possible score.
INSTALLS FAST AND EASY
- Scores and snaps easily without sawing.
- Coated glass mat facers for easy handing.
OFFERS SUPERIOR DURABILITY
- Offers a 12-month extended exposure warranty for typical weather conditions.
- Dimensionally stable under changes in temperature and relative humidity.
LOW-EMITTING MATERIALS
- Achieves UL GREENGUARD Gold Certification for low chemical emissions into indoor air during product usage. For more information, visit: ul.com/gg.
