Product details
Twelve-foot Firecode X is the tall-wall option when logistics and UL listings align: fewer horizontal joints can accelerate rated shaft production, but door heights, hoist beams, and temporary protection must prove out before committing trucks.
Forty-eight square feet at USG’s 2.2 lb per square foot nominal lands near 106 pounds per sheet—recalculate staging loads when bundles stack three high on a deck.
Inspector traceability depends on SCX edge printing; photograph bundles during receiving if disputes arise about swapped loads from the yard.
GREENGUARD Gold and ASTM C1396 Type X language support school and healthcare submittals where low-emitting documentation rides alongside fire ratings.
Never substitute EcoSmart ULIX or FC30 panels purely to save weight unless the UL book explicitly permits it—post-install discovery is catastrophically expensive.

Frequently asked questions
Why might 12 ft. sheets be rejected on site?
Why might 12 ft. sheets be rejected on site?
Hoist paths, door heights, and temporary protection limits can rule out long panels even when the UL design allows them.
Can I substitute EcoSmart for standard Firecode X?
Can I substitute EcoSmart for standard Firecode X?
Only when the UL design explicitly lists ULIX or allows the substitution; otherwise keep SCX with SCX.
What does GREENGUARD Gold add?
What does GREENGUARD Gold add?
It supports low-emitting material documentation common in schools and LEED-adjacent submittals per USG marketing.
How do I confirm panel type in the field?
How do I confirm panel type in the field?
Read the UL type printed along the long edge and compare to submittals before the board is covered.
