54 in. width option for layouts that benefit from wider modules
Key features
Same ASTM C1396 / UL / ICC-ES ESR-3365 positioning as UltraLight 1/2 in. per USG
Standard tapered long-edge detail for joint treatment per USG
Technical specifications
| R-Value | 0.45 |
|---|---|
| Thickness | 0.5 in |
| Width | 54.0 in |
| Length | 120.0 in |
| Coverage | 45.0 sq ft/pack |
| Material | Gypsum core with recycled face and back papers (Sheetrock UltraLight composite per USG) |
| Fire rating | Noncombustible gypsum core per typical gypsum-board listings; UL classification for surface-burning characteristics and noncombustibility per USG. Not a Type X (firecode) panel unless a separate Type X SKU is specified—verify UL design listings for rated assemblies. |
| Sound rating | Acoustic performance is assembly-dependent; gypsum finish layers contribute to STC in tested partition assemblies (ASTM E90). |
| Density | Nominal 1.25 lb/sq ft panel weight per USG product specifications |
| Construction type | ASTM C1396 1/2 in. gypsum wallboard and gypsum ceiling board per USG UltraLight listings |
| Application area | Interior walls and ceilings; engineered sag resistance may reduce need for separate sag-resistant ceiling board on typical ceiling spans per manufacturer—confirm with USG literature and code |
Product details
Fifty-four-inch-wide gypsum exists so nine-foot-high layouts can sometimes be covered with one vertical joint line instead of butt joints every four feet—when the architect’s module and supplier availability align, the detail can reduce tape footage and speed production.
This UltraLight panel yields forty-five square feet per sheet at 1.25 lb per square foot nominal per USG, roughly fifty-six pounds nominal per sheet for lift planning—confirm live distributor pricing and commodity codes because wide stock varies regionally.
Technical positioning stays within the UltraLight half-inch family: ASTM C1396, UL classification statements, ICC-ES ESR-3365 where ceiling documentation applies, and GREENGUARD Gold for low-emitting interiors.
Before bidding, validate that wide panels fit elevators, swing paths, and temporary openings; a paper savings on seams disappears if the module requires manual carry up exterior scaffolding.
As with all non-Type-X half-inch boards, keep rated assembly decisions in engineering and UL submittals—do not swap widths into a listed wall without written approval.

Frequently asked questions
Can I use UltraLight on ceilings?
Can I use UltraLight on ceilings?
USG markets UltraLight 1/2 in. panels with superior sag resistance and references ICC-ES ESR-3365 for ceiling installations in its product literature. Always follow the current USG installation guide and local code for span, framing, and fastener schedules.
Is UltraLight the same as Type X fire-rated drywall?
Is UltraLight the same as Type X fire-rated drywall?
No. Standard UltraLight 1/2 in. panels are not automatically interchangeable with Type X or proprietary fire-resistance boards. For rated assemblies, match the exact board type, thickness, and UL listing referenced in the assembly.
What is the approximate thermal contribution of one layer?
What is the approximate thermal contribution of one layer?
A single 1/2 in. gypsum finish layer is typically modeled near R-0.45 in residential R-value stacking; use your energy model and applicable standards for your climate and assembly.
Where should I confirm packaging and edge detail?
Where should I confirm packaging and edge detail?
Use the USG data/submittal sheet for the commodity code on your delivery ticket. Long edges are tapered for standard joint treatment; verify width and length on the master pack before cutting.
