A dry construction method that delivers strength and wind uplift performance normally sought in poured concrete decks.
A single layer roof deck solution with simple screw fastener panel assembly for both low- and steep-slope designs.
Roof assembly installation can occur immediately following the installation of our roof deck panels.
A lighter weight solution than poured concrete that can reduce the use of steel in the overall structure.
The only noncombustible Structural panel sheathing in accordance with the FM standard 4472 for use in low- and steep-slope roof systems.
