WeatherSmart® Rainscreen

Improve wall drying capacity

WeatherSmart® Rainscreen

WeatherSmart® Rainscreen reduces the risk of mold and rot by channeling water down and out of the wall assembly. Made of a 3D matrix polypropylene structure, it creates a 6 mm gap between the cladding and the weather-resistive barrier to ventilate and accelerate dry time. WeatherSmart Rainscreen is suitable behind most exterior claddings.

When used as part of the Henry® 1-2-3 Moisture Control System™, WeatherSmart Rainscreen is backed by an industry-leading 15-year warranty. Repairs are covered for both materials and labor with a single point of contact.
