This lightweight Type X drywall panel delivers identical fire ratings to standard alternatives while weighing just 1.8 pounds per square foot — roughly 86.4 pounds per 4x12 sheet. That’s 22% lighter than standard 5/8 inch Type X panels. For commercial contractors handling dozens of sheets daily, that weight reduction translates directly to reduced installer fatigue and lower transportation costs per load.
The panel combines a non-combustible gypsum core with 100% recycled paper facings, meeting fire code requirements without the typical weight penalty. Testing confirms it provides the same 1-hour fire resistance as standard Type X in single-layer designs.
Weight Reduction Without Performance Compromise
The numbers tell the story contractors care about:
| Specification | EcoSmart | Standard Type X |
|---|---|---|
| Weight per sq ft | 1.8 lbs | ~2.2 lbs |
| Weight per 4x12 sheet | 86.4 lbs | ~105.6 lbs |
| Weight reduction | 22% | — |
| Fire rating | 1-hour | 1-hour |
Reduced weight allows for easier overhead installation and reduced transport costs. On multi-story commercial projects common in Billings and Missoula, that 22% weight reduction affects structural load calculations. It also means crews can handle more sheets per day before fatigue sets in — particularly relevant on ceiling installations where every pound matters.
Installation requires no special tools and handles like standard drywall but with less fatigue due to weight. Standard 1-1/4” or 1-1/2” drywall screws work fine, with spacing following local codes — typically 12” on walls and 16” on ceilings.
Environmental Certifications That Matter
USG didn’t just make this panel lighter — they engineered it for green building certifications:
| Environmental Metric | Performance |
|---|---|
| Recycled content | 94.6% |
| Global warming potential reduction | Up to 21% |
| Water use reduction | Up to 25% during manufacturing |
| USDA Biobased content | 100% |
| VOC certification | GREENGUARD Gold Certified |
The panels are Living Building Challenge Red List Free and compliant with California Section 01350. For Montana university and hospital projects pursuing LEED certification, these panels contribute to LEED v4 credits.
The recycled content isn’t just marketing. The 100% recycled paper facings and 94.6% total recycled content represent genuine material diversion from landfills. Combined with the manufacturing improvements — up to 25% reduction in water use and up to 21% lower global warming potential — this panel delivers measurable environmental benefits without sacrificing performance.
Fire Performance and Code Compliance
These panels are UL-listed for use in over 400 fire-resistance-rated UL designs, suitable for walls, columns, and floor/ceiling applications. The ULIX (Ultra-Light Innovation Type X) classification confirms full Type X fire performance in a lighter package.
ASTM compliance includes C1396, C473, E136, and E84 — all the standards commercial contractors need for specification compliance. The panels are compatible with all Sheetrock brand joint tapes and compounds, both ready-mix and setting-type.
Standard finishing applies — Level 4 or 5 as per standard gypsum board finishing standards. No special compounds or techniques required. The tapered long edges and square ends work exactly like standard drywall for seamless joint treatment.
The Bottom Line
With 286 Home Depot reviews noting it as highly rated for ease of handling and environmental benefits, this has become a standard product in the industry with strong contractor adoption. The weight reduction matters most where it counts — overhead installation, multi-story transport, and end-of-day installer fatigue.
For remote Montana jobsites where every delivery mile costs money, hauling 22% less weight per truckload adds up. For commercial contractors bidding hospital additions and university buildings where LEED points influence selection, the documented environmental benefits provide competitive advantage. And for any crew installing ceilings all day, those 19 pounds saved per sheet make a real difference by quitting time.
The trade-off? Potentially higher costs compared to standard drywall options. But when factoring in reduced transportation costs, faster installation from less fatigue, and the ability to meet green building requirements, EcoSmart panels earn their place on commercial projects where both performance and sustainability matter.
Frequently Asked Questions
Q: How much does a sheet of USG Sheetrock Firecode X EcoSmart actually weigh?
A 4x12 sheet of USG Sheetrock Firecode X EcoSmart weighs approximately 86.4 pounds, which is about 22% lighter than standard 5/8” Type X drywall. The weight reduction comes from USG’s lightweight formulation while maintaining the same fire-resistant properties.
Q: Does the lighter weight of EcoSmart panels affect their fire rating?
No, USG Sheetrock Firecode X EcoSmart panels provide the same 1-hour fire resistance rating as standard Type X drywall in single-layer designs. The panels are UL-listed for use in over 400 fire-resistance-rated assemblies and carry the ULIX (Ultra-Light Innovation Type X) classification.
Q: What size screws and spacing should I use for installing these panels?
USG Sheetrock Firecode X EcoSmart panels use standard 1-1/4” or 1-1/2” drywall screws with typical spacing of 12 inches on walls and 16 inches on ceilings, following local codes. No special fasteners or installation techniques are required compared to standard drywall.
Q: What makes these panels “EcoSmart” compared to regular Type X drywall?
USG Sheetrock Firecode X EcoSmart panels contain 94.6% recycled content, feature 100% recycled paper facings, and are manufactured with up to 25% less water use and up to 21% lower global warming potential than conventional Type X. The panels are GREENGUARD Gold Certified for low VOC emissions and Living Building Challenge Red List Free.
Q: Can I use standard joint compound and finishing techniques with these panels?
Yes, USG Sheetrock Firecode X EcoSmart panels are compatible with all Sheetrock brand joint tapes and compounds, both ready-mix and setting-type. The panels feature tapered long edges for standard finishing to Level 4 or 5 as per typical gypsum board standards.
Q: What certifications do these panels have for green building projects?
USG Sheetrock Firecode X EcoSmart panels are GREENGUARD Gold Certified, USDA Certified Biobased Product (100%), Living Building Challenge Red List Free, California Section 01350 Compliant, and eligible for LEED v4 credits. The panels meet ASTM standards C1396, C473, E136, and E84.
