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® Air and Water Barrier System is the ideal solution. This system, including the engineered wood sheathing panels and accessories, acts as an air and water barrier—so you can finally say goodbye to building wrap.
