The ventilated Delta-Dry rainscreen from Cosella-Dörken acts as a water-resistant barrier within a wall cavity and allows for drainage. It is suited for applications behind absorptive claddings, such as stucco, manufactured stone, cement board, brick veneer, and natural stone, and over substrates such as oriented strand board, plywood, and exterior-grade sheathing. New 11mm-deep, 3D dimples keep water from crossing into the wall cavity, while a dual air space allows wet walls to dry out. The polyethylene rainscreen will not rot, warp, mold, or trap water. It requires no special tools to install and can be used on new or retrofit construction. cosella-dorken.com
