By integrating water-resistive and air barrier (WRB-AB) directly into gypsum sheathing panel core, DensElement™ Barrier System with AquaKOR™ Technology reduces time needed to install exterior walls in commercial construction. This all-in-one sheathing system, which exhibits vapor permeability that helps mitigate moisture issues in wall cavity, can be sealed with PROSOCO R-Guard® FastFlash® liquid flashing, which fills and seals all joints, fasteners, and other penetrations.
