RainDrop®
RainDrop’s innovative drainage channels keep water out of the wall system. The channels won’t crimp, collapse, or flatten, ensuring water will drain no matter how tightly cladding is nailed to the wall. Because it’s not perforated, RainDrop resists air and water infiltration. Plus it breathes to allow moisture vapor to escape. With its high tear resistance and translucent design, installation is quick and easy with no job site waste. And it stays UV-stable up to 4 months. RainDrop is an ideal secondary weather barrier for fiber cement, vinyl, foam-backed vinyl, and wood sidings.

3 Drainage testing was conducted in accordance with ASTM E 2273-03 using a cementitious base coat as required for EIFS and adhered veneers. The GreenGuard
® RainDrop
® was installed directly over the sheathing and the exterior side of the RainDrop
® was covered with a layer of Grade D water-resistive barrier/building paper as required in the International Residential Code for stucco wall assemblies.
