WeatherPRO® Technology was designed with the harsh North American climates in mind, allowing high airflow while providing excellent defense against weather infiltration. With no moving parts, the unique baffle system effectively deflects rain and snow, allowing water to drain harmlessly out of the drainage openings. The Duraflo® WeatherPRO Series PRO50 is subjected to extensive testing such as the Miami Dade county hurricane test, as well as extreme cold weather impact testing.
