• Underwriters Laboratories Inc. (UL) Classification as to fire resistance, surface-burning
characteristics and noncombustibility
• Comply with ASTM C1396, Standard Specification for Gypsum Board, for 5/8 in. (15.9 mm)
Type X gypsum wallboard
• Oer comparable sound, strength, sag and impact resistance to standard 5/8 in. (15.9 mm) Type X

(meets CA 01350)
USG Sheetrock® Brand UltraLight Panels Firecode® X are formulated to achieve all of the strength
and performance characteristics as standard 5/8 in. (15.9 mm) USG Sheetrock® Brand Firecode® X
Panels at a reduced weight. These lightweight 5/8 in. (15.9 mm) Type X panels feature a
noncombustible gypsum core that is encased in 100% recycled face and back papers. The natural
finish face paper is folded around the long edges to reinforce and protect the core, and the ends
are cut square and even. The long edges of the panels are tapered, allowing joints to be reinforced
and concealed with USG Sheetrock® Brand joint treatment systems. The panels are UL Classified
for fire resistance and can be used in any UL design in which Type ULX panels are listed. On the
face along the long edge of each panel, the UL Type Designation is printed for easy identification
by building inspectors.
• Commercial or residential applications where 5/8 in. (15.9 mm) Type X panels are required
• New or repair and remodel construction
• Load-bearing and non-load-bearing wood- or steel-framed fire-rated walls
1. Avoid exposure to sustained temperatures exceeding 125 °F (52 °C).
2. Avoid exposure to excessive, repetitive or continuous moisture before, during and after
installation. Eliminate sources of moisture immediately.
3. Must be stored o the ground and under cover in accordance with Gypsum Association's GA-801,
Handling and Storage of Gypsum Panel Products.
For maximum framing spacing in non-fire-resistance-rated applications of gypsum panel products,
refer to Gypsum Association's GA-216, Specifications for the Application and Finishing of Gypsum
Panel Products or ASTM C840, Standard Specification for Application and Finishing of Gypsum
Board. For fire-resistance-rated applications, refer to the published UL Design or GA File Number.
