UL Type FC30 edge marking for inspector verification per USG
Key features
Lighter 1.7 lb/sq ft nominal panel than standard 2.2 lb/sq ft Firecode X per USG data
Twelve-foot module for tall interiors when FC30-listed designs apply
Technical specifications
| R-Value | 0.56 |
|---|---|
| Thickness | 0.625 in |
| Width | 48.0 in |

| Material | Innovative noncombustible gypsum core with recycled papers—EcoSmart Firecode 30 composite per USG |
| Fire rating | 5/8 in. panel (UL Type FC30) per USG EcoSmart Firecode 30; USG states ASTM C1396 scope includes non-Type X gypsum wallboard for this product while UL classifies fire resistance for listed assemblies—match the published UL design to FC30, not generic Type X assumptions. |
| Sound rating | Acoustic performance is assembly-dependent; gypsum finish layers contribute to STC in tested partition assemblies (ASTM E90). |
| Density | Nominal 1.7 lb/sq ft per USG EcoSmart Firecode 30 specifications |
| Construction type | ASTM C1396 5/8 in. gypsum wallboard scope per USG EcoSmart Firecode 30 (USG states non-Type X classification in product overview) |
| Application area | Interior wall and ceiling assemblies where UL designs list FC30 panels; not automatically interchangeable with SCX or ULIX Type X per USG |
Product details
EcoSmart Firecode 30 addresses assemblies that call for UL Type FC30—not generic Type X language: USG’s overview ties ASTM C1396 to five-eighths gypsum wallboard while clarifying non-Type X classification in the product story, even though UL still classifies FC30 for specific fire-resistance-rated designs.
Twelve-foot sheets cover forty-eight square feet; at 1.7 lb per square foot nominal per USG, plan near eighty-two pounds per sheet—lighter than standard SCX planning weights but not automatically interchangeable layer-for-layer.
GREENGUARD Gold, biobased/recycled positioning, and printed FC30 edge marks belong in sustainability and inspection checklists alike; photograph stamps before cover-up on contentious jobs.
Do not use FC30 in a shower wet wall without a system detail—USG lists Moisture Resistance: No on this product page; wet areas need membrane and backer strategies from TCNA-aligned documentation.
Estimators comparing truck weights should document FC30 versus SCX versus ULIX densities separately; accidental bundle mixing voids both safety plans and UL compliance.

Frequently asked questions
Is Firecode 30 the same as Type X?
Is Firecode 30 the same as Type X?
USG’s EcoSmart Firecode 30 overview references ASTM C1396 language for non-Type X gypsum wallboard while UL still classifies FC30 for listed assemblies—read the UL design, not assumptions.
When would I pick FC30 instead of Firecode X?
When would I pick FC30 instead of Firecode X?
When the architect’s UL file or assembly schedule explicitly names FC30 panels and the tested layers match what you hang.
Can I use FC30 in a shower wet wall?
Can I use FC30 in a shower wet wall?
USG lists Moisture Resistance: No on this product page—wet-area detailing still needs the right board and membrane system.
How do estimators compare weight to SCX?
How do estimators compare weight to SCX?
Use 1.7 lb/sq ft nominal for EcoSmart Firecode 30 versus 2.2 lb/sq ft for standard Firecode X when planning crane picks.
