Driwalltm Rainscreen 10 mm is a 0.40-inch-thick, randomly oriented geometricpatterned drainage and ventilation mat.It is designed to eliminate moisture and moisture vapor in masonry and otherexterior veneer applications. Driwalltm Rainscreen is produced from anextruded polymer matrix of tangled monofilaments. The three-dimensional matis heat laminated to a non-woven lightweight, breathable fabric to provide aseparation from cementitious sidings. The monofilaments are heat-welded atthe junctions to form a structure that spaces exterior veneer away from theinner sheathing.The product is useful in cavity wall designs and rainscreen systems in whichan airspace is needed for drainage and ventilation. When DRIWALLTMRAINSCREEN is used, no mortar or other debris can enter the cavity, whichensures proper drainage and ventilation.
