The ForceField® Weather Barrier System advanced weather resistive barrier (WRB) and sheathing system is perfect for wood-framed residential, multifamily, and light commercial structures. With our ForceField® Sheathing Panels, you can secure your entire structure efficiently, from walls to sloped roofs. Partnered with ForceField® Accessories from Georgia-Pacific, our system accelerates the drying-in process, improving your structure’s energy efficiency.
ForceField® Sheathing Panels are easy to install, just like standard OSB or plywood sheathing, making them ideal for varied applications. Notably, these panels have demonstrated more than 90% drainage efficiency when installed behind rigid insulation or multiple types of claddings in wall applications (as tested per ASTM 2273).
