Designed for use with EIFS, exterior sheathing has built-in water drainage channels embossed on the back of each panel, enabling incidental water that may intrude the wall system to exit quickly. Unlike exposed glass-mat products, Aqua-Tough's gypsum/cellulose fiber formulation won't tear or puncture when fastened.
