Whether you’re building a 5-story multifamily residential project or 6 floors-plus with conventional or podium construction, Georgia-Pacific has your integrated sheathing solution. For fire-rated multifamily structures, choose DensElement® Barrier System. By filling microscopic voids in the glass mat and gypsum core via AquaKor™ Technology, a hydrophobic, monolithic surface is created that blocks bulk water while retaining vapor permeability. No additional air or water barrier is needed, saving time. For a maximum 5-story residential multifamily project or for 5 stories of multifamily residential atop a mixed-use project, ForceField® Weather Barrier System is the ideal solution. This system, including the engineered wood sheathing panels with DryGuard® Technology and accessories, acts as an air and water barrier—so you can finally say goodbye to building wrap.
