UL G575 exclusive 2-hour fire-rated assembly per ASTM E119. Same code compliance as gypcrete, zero cure window.
4 lbs/SF vs. 10–15 lbs/SF for gypcrete. Less dead load on your structure, lighter lifts for your crew.
No temperature minimums, no rain delays. Install year-round on any floor, any condition.
Three reasons your current subfloor line isn't building the margin your business needs.
Commodity drywall gets price-shopped on every order. No spec protection, no lock-in, and no reason for the contractor to stay loyal to your branch.
Without architect specification, you're selling on price. DragonBoard flips that architects specify it by UL design number and GCs pull it through your branch.
Commodity subfloor margins track lumber cycles. DragonBoard's spec-driven demand is structurally insulated from commodity price pressure.
DragonBoard is backed by Super Stud Building Products, trusted by contractors, architects, and dealers since 1973. When you specify DragonBoard, you're working with the team that supplies the steel framing underneath it.
