Transforming the Building Envelope

The DensElement™ System is a new, all-in-one, water-resistive and air barrier (WRB-AB) system solution that completely eliminates an additional WRB over the face of the sheathing in commercial construction.

The enhanced, fiberglass mat sheathing panel integrates a WRB-AB directly within its core, which offers high vapor permeability. In combination with a GP-approved liquid flashing, this allows the exterior wall cavity to dry if moisture is introduced and helps prevent potential mildew, mold and deterioration.

Faster. Safer. Smarter.

Contractors can save time, labor and materials compared to traditional WRB-AB methods, like building wrap, fluid-applied membranes or self-adhered membranes. Safety risks are also reduced with less time spent on the job and in elevated positions, like scaffolding, or on the job as a whole.

The DensElement™ Barrier System is the latest evolution in the Georgia-Pacific Gypsum portfolio of Dens® GOLD fiberglass mat gypsum panels. Enhanced with AquaKOR™ Technology, DensElement Sheathing incorporates the same high quality and performance that architects and contractors have trusted for the last 30 years.

System Solution

The DensElement™ Barrier System excels as a high-performance water-resistive and air barrier in rigorous field and laboratory testing. The system incorporates:
  • DensElement™ Sheathing with AquaKOR™ Technology
  • GP-approved PROSOCO R-Guard® FastFlash® liquid flashing (to fill and seal joints, fasteners, openings, penetrations and transitions)


DensElement Sheathing installs in the same manner as DensGlass® Sheathing or other traditional fiberglass mat gypsum sheathing panels. After the sheathing is installed, the system is finished using a GP-approved liquid flashing to seal joints, fasteners, openings, penetrations and transitions.
  • Refer to the installation instructions and installation video on this page.
  • The DensElement™ Barrier System holds an International Code Council Evaluation Service (ICC-ES®) ESR for IRC, IBC Chapter 1, Section 104 Alternative Materials Compliance.
