Keene Driwall Rainscreen Drainage and Ventilation Mat, 1/4-inch Thick x 4' Wide x 65' Roll

Keene Driwall Rainscreen is a 1/4-inch thick, randomly oriented geometric-patterned drainage and ventilation mat.

It is designed to eliminate moisture and moisture vapor in masonry and other exterior veneer applications. Driwall Rainscreen is produced from an extruded polymer matrix of tangled monofilaments. The three-dimensional mat is heat laminated to a non-woven lightweight, breathable fabric to provide a separation from cementitious sidings. The monofilaments are heat-welded at the junctions to form a structure that spaces exterior veneer away from the inner sheathing.

The product is useful in cavity wall designs and rainscreen systems in which an airspace is needed for drainage and ventilation. When Driwall Rainscreen is used, no mortar or other debris can enter the cavity, which
ensures proper drainage and ventilation.
