Used for a more rigid vinyl siding base and also adds insulation value. Used by professional installers under vinyl and other kinds of siding. WeatherAll Pro breathes, we put over 1,000 vapor holes* in every square foot of WeatherAll Pro®. These tiny holes enhance water vapor permeability. This important feature helps ensure that water vapor can escape the wall cavity. Trapped water vapor can cause mold formation and, if unnoticed, can lead to structural damage.
