The Delta-Dry advanced ventilated rainscreen is designed for use behind absorptive cladding such as manufactured stone, stucco, and natural stone. The impermeable membrane is made from high-density polyethylene that provides dual-sided drainage, a complete capillary break, and drying capacity. Its double-sided dimple design ventilates the cavity and allows moisture to escape. Install between exterior sheathing and cladding to protect structures from water intrusion.
