True or False: Housewrap is designed to stop water vapor from passing through.

Housewrap is a building material that plays a significant role in moisture management, especially in the construction of homes. Its primary function is to allow water vapor to escape from the structure while preventing liquid water from entering. This permeability to vapor is crucial because it helps to reduce the risk of mold and rot within walls by allowing moisture to evaporate, thereby maintaining a more stable indoor environment.

Given this function, housewrap is not designed to stop water vapor from passing through; instead, it facilitates the escape of vapor while acting as a barrier against liquid water. This unique property makes housewrap an essential component in modern building practices, as it aids in regulating moisture without trapping it inside wall cavities. Recognizing this characteristic clarifies why the statement is false.
