WeatherSmart® Rainscreen

Improve wall drying capacity

WeatherSmart® Rainscreen

Compatible with all cladding types, WeatherSmart® Rainscreen provides a 6mm gap between cladding and weather-resistive barrier, creating space for ventilation. The 3D matrix polypropylene strands channel water down and out of the wall assembly and the built-in fabric protects the gap from debris. The result is faster-drying wall assemblies and reduced risk of unhealthy mold, rot and mildew.

WeatherSmart® Rainscreen is an accessory to the Fortifiber® 1-2-3 Moisture Control System™ of flashings, weather-resistive barriers and sealants. All system components can be used together with confidence. WeatherSmart® Rainscreen may carry a 15-year warranty.
