Material & UV Protection
Material - Cold Impact Tested
WeatherPRO® Upward Venting
The solid sidewalls and upward venting design behind the WeatherPRO® vents have been engineered to increase
weather protection while improving ventilation in high wind areas. The solid sidewalls work in part with the interior
baes, providing the rst line of defense against driving rain and snow. The solid sidewalls also act to push wind up
and over the cap of the vent, as opposed to under, like a traditional roof vent. This airow over the cap of the vent
creates negative pressure to draw air from the attic.
The WeatherPRO® line of vents are manufactured from all virgin polypropylene allowing them to withstand the most
extreme climates. The material used in manufacturing the WeatherPRO® Series is cold impact tested at -40 degrees.
The material remains functional, exible and resilient to damage even when installed with a nail gun.
